Description

FIELD OF THE INVENTION

The present invention relates to agent based systems and more particularly to a mobile computing environment that accesses the Internet to obtain product information for a user through an interface support framework.

BACKGROUND OF THE INVENTION

Computer assistance in all environments is increasingly necessary as computer technology becomes increasingly embedded in society. Mobile computing technology addresses this issue by allowing the individual to access computer related information at all times and in all environments.

One of the first major advances in mobile computer technology was the Personal Digital Assistant (PDA). A PDA allowed a user to access computer related information, yet fitted in the palm of the hand. Utilizing a PDA the user could organize personal affairs, write notes, calculate equations, and record contact numbers an address book. In addition, PDAs were usually capable of interfacing with a desktop computer, typically through a wire connection. The connection allowed the PDA to download information and upload information, with the desktop computer. Later developments gave the PDA wireless capabilities. The wireless capabilities allowed the PDA to interact with other computers that were not physically connected to the PDA.

Wireless PDAs could communicate with computers that were connected to the World Wide Web, and soon led to PDAs capable of Web browsing. One of the first companies to develop Web browsing capabilities for PDAs was Intercom.

Intercom's Falcon Mobile Server allowed PDAs with Web functions to directly connect to a host computer. Just by installing the software onto the host server, PDA terminals were able to access information through the World Wide Web.

Currently, more integration in mobile computing is desired. Nokia, an Irving Tex. company, has partially addressed the integration issue by developing the Nokia 9000 wireless voice phone. The Nokia 9000 includes a small keyboard, a specialized Web browser from microbrowser vendor Unwired Planet, Inc., and a small VGA monitor. Nokia worked with Ericsson Inc, Motorola Inc. and Unwired Planet to establish the Wireless Application Protocal (WAP), a standardized browser technology and server format. WAP gave manufacturers a standard way to put data capability into wireless phones, and allowed carriers to do more over-the-air management. For example, if a carrier wanted a field trial of a new data service, the carrier could implement the service on a server, deliver it to a phone through the microbrowser and adjust the service if they found the service unsatisfactory.

Prior Art FIG. 1A is a diagram of prior art mobile computing solutions based on web portal networks. In the Prior Art, the user 10 must deal separately with each participant of the network. In the Prior Art mobile computing solution, the user 10 utilizes an Internet service provider (ISP) 12 to gain access to a web portal 14. The web portal 14 accesses third party services 16 which provide information directly to the user 10. However, in addition to dealing with the Internet Service Provider 12, the user 10 must purchase the wireless device from the device manufactures or retailers 18. In most cases the user 10 would also have to purchase the browser from the browser provider 20. Generally, the user would have to pay the wireless communication cost, leading to the user needing to deal with the phone company 22. And finally, any web purchases would lead to the user 10 needing to deal with the credit card company 24. It is obvious that a coordinated and packaged service would be an ideal mobile computing solution. Furthermore, a coordinated and packaged service which made use of agents would be highly desired.

Agent based technology has become increasingly important for use with applications designed to interact with a user for performing various computer based tasks in foreground and background modes. Agent software comprises computer programs that are set on behalf of users to perform routine, tedious and time-consuming tasks. To be useful to an individual user, an agent must be personalized to the individual user's goals, habits and preferences. Thus, there exists a substantial requirement for the agent to efficiently and effectively acquire user-specific knowledge from the user and utilize it to perform tasks on behalf of the user.

The concept of agency, or the user of agents, is well established. An agent is a person authorized by another person, typically referred to as a principal, to act on behalf of the principal. In this manner the principal empowers the agent to perform any of the tasks that the principal is unwilling or unable to perform. For example, an insurance agent may handle all of the insurance requirements for a principal, or a talent agent may act on behalf of a performer to arrange concert dates.

With the advent of the computer, a new domain for employing agents has arrived. Significant advances in the realm of expert systems enable computer programs to act on behalf of computer users to perform routine, tedious and other time-consuming tasks. These computer programs are referred to as "software agents."

Moreover, there has been a recent proliferation of computer and communication networks. These networks permit a user to access vast amounts of information and services without, essentially, any geographical boundaries. Thus, a software agent has a rich environment to perform a large number of tasks on behalf of a user. For example, it is now possible for an agent to make an airline reservation, purchase the ticket, and have the ticket delivered directly to a user. Similarly, an agent could scan the Internet and obtain information ranging from the latest sports or news to a particular graduate thesis in applied physics. Current solutions fail to apply agent technology to provide targeted acquisition of information for a user's upcoming events.

SUMMARY OF THE INVENTION

A system is disclosed that facilitates web-based information retrieval and display system. A wireless phone or similar hand-held wireless device with Internet Protocol capability is combined with other peripherals to provide a portable portal into the Internet. The wireless device prompts a user to input information of interest to the user. This information is transmitted a query to a service routine (running on a Web server). The service routine then queries the Web to find price, shipping and availability information from various Web suppliers. This information is formatted and displayed on the hand-held device's screen through an interface support framework. The user may then use the hand-held device to place an order interactively.

DETAILED DESCRIPTION

A preferred embodiment of a system in accordance with the present invention is preferably practiced in the context of a personal computer such as an IBM compatible personal computer, Apple Macintosh computer or UNIX based workstation. A representative hardware environment is depicted in FIG. 1, which illustrates a typical hardware configuration of a workstation in accordance with a preferred embodiment having a central processing unit 110, such as a microprocessor, and a number of other units interconnected via a system bus 112. The workstation shown in FIG. 1 includes a Random Access Memory (RAM) 114, Read Only Memory (ROM) 116, an I/O adapter 118 for connecting peripheral devices such as disk storage units 120 to the bus 112, a user interface adapter 122 for connecting a keyboard 124, a mouse 126, a speaker 128, a microphone 132, and/or other user interface devices such as a touch screen (not shown) to the bus 112, communication adapter 134 for connecting the workstation to a communication network (e.g., a data processing network) and a display adapter 136 for connecting the bus 112 to a display device 138. The workstation typically has resident thereon an operating system such as the Microsoft Windows NT or Windows/95 Operating System (OS), the IBM OS/2 operating system, the MAC OS, or UNIX operating system. Those skilled in the art will appreciate that the present invention may also be implemented on platforms and operating systems other than those mentioned.

A preferred embodiment is written using JAVA, C, and the C++ language and utilizes object oriented programming methodology. Object oriented programming (OOP) has become increasingly used to develop complex applications. As OOP moves toward the mainstream of software design and development, various software solutions require adaptation to make use of the benefits of OOP. A need exists for these principles of OOP to be applied to a messaging interface of an electronic messaging system such that a set of OOP classes and objects for the messaging interface can be provided. OOP is a process of developing computer software using objects, including the steps of analyzing the problem, designing the system, and constructing the program. An object is a software package that contains both data and a collection of related structures and procedures. Since it contains both data and a collection of structures and procedures, it can be visualized as a self-sufficient component that does not require other additional structures, procedures or data to perform its specific task. OOP, therefore, views a computer program as a collection of largely autonomous components, called objects, each of which is responsible for a specific task. This concept of packaging data, structures, and procedures together in one component or module is called encapsulation.

In general, OOP components are reusable software modules which present an interface that conforms to an object model and which are accessed at run-time through a component integration architecture. A component integration architecture is a set of architecture mechanisms which allow software modules in different process spaces to utilize each others capabilities or functions. This is generally done by assuming a common component object model on which to build the architecture.

It is worthwhile to differentiate between an object and a class of objects at this point. An object is a single instance of the class of objects, which is often just called a class. A class of objects can be viewed as a blueprint, from which many objects can be formed.

OOP allows the programmer to create an object that is a part of another object. For example, the object representing a piston engine is said to have a composition-relationship with the object representing a piston. In reality, a piston engine comprises a piston, valves and many other components; the fact that a piston is an element of a piston engine can be logically and semantically represented in OOP by two objects.

OOP also allows creation of an object that "depends from" another object. If there are two objects, one representing a piston engine and the other representing a piston engine wherein the piston is made of ceramic, then the relationship between the two objects is not that of composition. A ceramic piston engine does not make up a piston engine. Rather it is merely one kind of piston engine that has one more limitation than the piston engine; its piston is made of ceramic. In this case, the object representing the ceramic piston engine is called a derived object, and it inherits all of the aspects of the object representing the piston engine and adds further limitation or detail to it. The object representing the ceramic piston engine "depends from" the object representing the piston engine. The relationship between these objects is called inheritance.

When the object or class representing the ceramic piston engine inherits all of the aspects of the objects representing the piston engine, it inherits the thermal characteristics of a standard piston defined in the piston engine class. However, the ceramic piston engine object overrides these ceramic specific thermal characteristics, which are typically different from those associated with a metal piston. It skips over the original and uses new functions related to ceramic pistons. Different kinds of piston engines have different characteristics, but may have the same underlying functions associated with it (e.g., how many pistons in the engine, ignition sequences, lubrication, etc.). To access each of these functions in any piston engine object, a programmer would call the same functions with the same names, but each type of piston engine may have different/overriding implementations of functions behind the same name. This ability to hide different implementations of a function behind the same name is called polymorphism and it greatly simplifies communication among objects.

With the concepts of composition-relationship, encapsulation, inheritance and polymorphism, an object can represent just about anything in the real world. In fact, our logical perception of the reality is the only limit on determining the kinds of things that can become objects in object-oriented software. Some typical categories are as follows:

Objects can represent physical objects, such as automobiles in a traffic-flow simulation, electrical components in a circuit-design program, countries in an economics model, or aircraft in an air-traffic-control system.

Objects can represent elements of the computer-user environment such as windows, menus or graphics objects.

An object can represent an inventory, such as a personnel file or a table of the latitudes and longitudes of cities.

An object can represent user-defined data types such as time, angles, and complex numbers, or points on the plane.

With this enormous capability of an object to represent just about any logically separable matters, OOP allows the software developer to design and implement a computer program that is a model of some aspects of reality, whether that reality is a physical entity, a process, a system, or a composition of matter. Since the object can represent anything, the software developer can create an object which can be used as a component in a larger software project in the future.

If 90% of a new OOP software program consists of proven, existing components made from preexisting reusable objects, then only the remaining 10% of the new software project has to be written and tested from scratch. Since 90% already came from an inventory of extensively tested reusable objects, the potential domain from which an error could originate is 10% of the program. As a result, OOP enables software developers to build objects out of other, previously built, objects.

This process closely resembles complex machinery being built out of assemblies and sub-assemblies. OOP technology, therefore, makes software engineering more like hardware engineering in that software is built from existing components, which are available to the developer as objects. All this adds up to an improved quality of the software as well as an increased speed of its development.

Programming languages are beginning to fully support the OOP principles, such as encapsulation, inheritance, polymorphism, and composition-relationship. With the advent of the C++ language, many commercial software developers have embraced OOP. C++ is an OOP language that offers a fast, machine-executable code. Furthermore, C++ is suitable for both commercial-application and systems-programming projects. For now, C++ appears to be the most popular choice among many OOP programmers, but there is a host of other OOP languages, such as Smalltalk, common lisp object system (CLOS), and Eiffel. Additionally, OOP capabilities are being added to more traditional popular computer programming languages such as Pascal.

The benefits of object classes can be summarized, as follows:

Objects and their corresponding classes break down complex programming problems into many smaller, simpler problems.

Encapsulation enforces data abstraction through the organization of data into small, independent objects that can communicate with each other. Encapsulation protects the data in an object from accidental damage, but allows other objects to interact with that data by calling the object's member functions and structures.

Subclassing and inheritance make it possible to extend and modify objects through deriving new kinds of objects from the standard classes available in the system. Thus, new capabilities are created without having to start from scratch.

Polymorphism and multiple inheritance make it possible for different programmers to mix and match characteristics of many different classes and create specialized objects that can still work with related objects in predictable ways.

Class hierarchies and containment hierarchies provide a flexible mechanism for modeling real-world objects and the relationships among them.

Libraries of reusable classes are useful in many situations, but they also have some limitations. For example:

Complexity. In a complex system, the class hierarchies for related classes can become extremely confusing, with many dozens or even hundreds of classes.

Flow of control. A program written with the aid of class libraries is still responsible for the flow of control (i.e., it must control the interactions among all the objects created from a particular library). The programmer has to decide which functions to call at what times for which kinds of objects.

Duplication of effort. Although class libraries allow programmers to use and reuse many small pieces of code, each programmer puts those pieces together in a different way. Two different programmers can use the same set of class libraries to write two programs that do exactly the same thing but whose internal structure (i.e., design) may be quite different, depending on hundreds of small decisions each programmer makes along the way. Inevitably, similar pieces of code end up doing similar things in slightly different ways and do not work as well together as they should.

Class libraries are very flexible. As programs grow more complex, more programmers are forced to reinvent basic solutions to basic problems over and over again. A relatively new extension of the class library concept is to have a framework of class libraries. This framework is more complex and consists of significant collections of collaborating classes that capture both the small scale patterns and major mechanisms that implement the common requirements and design in a specific application domain. They were first developed to free application programmers from the chores involved in displaying menus, windows, dialog boxes, and other standard user interface elements for personal computers.

Frameworks also represent a change in the way programmers think about the interaction between the code they write and code written by others. In the early days of procedural programming, the programmer called libraries provided by the operating system to perform certain tasks, but basically the program executed down the page from start to finish, and the programmer was solely responsible for the flow of control. This was appropriate for printing out paychecks, calculating a mathematical table, or solving other problems with a program that executed in just one way.

The development of graphical user interfaces began to turn this procedural programming arrangement inside out. These interfaces allow the user, rather than program logic, to drive the program and decide when certain actions should be performed. Today, most personal computer software accomplishes this by means of an event loop which monitors the mouse, keyboard, and other sources of external events and calls the appropriate parts of the programmer's code according to actions that the user performs. The programmer no longer determines the order in which events occur. Instead, a program is divided into separate pieces that are called at unpredictable times and in an unpredictable order. By relinquishing control in this way to users, the developer creates a program that is much easier to use. Nevertheless, individual pieces of the program written by the developer still call libraries provided by the operating system to accomplish certain tasks, and the programmer must still determine the flow of control within each piece after being called by the event loop. Application code still "sits on top of" the system.

Even event loop programs require programmers to write a lot of code that should not need to be written separately for every application. The concept of an application framework carries the event loop concept further. Instead of dealing with all the nuts and bolts of constructing basic menus, windows, and dialog boxes and then making these things all work together, programmers using application frameworks start with working application code and basic user interface elements in place. Subsequently, they build from there by replacing some of the generic capabilities of the framework with the specific capabilities of the intended application.

Application frameworks reduce the total amount of code that a programmer has to write from scratch. However, because the framework is really a generic application that displays windows, supports copy and paste, and so on, the programmer can also relinquish control to a greater degree than event loop programs permit. The framework code takes care of almost all event handling and flow of control, and the programmer's code is called only when the framework needs it (e.g., to create or manipulate a proprietary data structure).

A programmer writing a framework program not only relinquishes control to the user (as is also true for event loop programs), but also relinquishes the detailed flow of control within the program to the framework. This approach allows the creation of more complex systems that work together in interesting ways, as opposed to isolated programs, having custom code, being created over and over again for similar problems.

Thus, as is explained above, a framework basically is a collection of cooperating classes that make up a reusable design solution for a given problem domain. It typically includes objects that provide default behavior (e.g., for menus and windows), and programmers use it by inheriting some of that default behavior and overriding other behavior so that the framework calls application code at the appropriate times.

There are three main differences between frameworks and class libraries:

Behavior versus protocol. Class libraries are essentially collections of behaviors that you can call when you want those individual behaviors in your program. A framework, on the other hand, provides not only behavior but also the protocol or set of rules that govern the ways in which behaviors can be combined, including rules for what a programmer is supposed to provide versus what the framework provides.

Call versus override. With a class library, the code the programmer instantiates objects and calls their member functions. It's possible to instantiate and call objects in the same way with a framework (i.e., to treat the framework as a class library), but to take full advantage of a framework's reusable design, a programmer typically writes code that overrides and is called by the framework. The framework manages the flow of control among its objects. Writing a program involves dividing responsibilities among the various pieces of software that are called by the framework rather than specifying how the different pieces should work together.

Implementation versus design. With class libraries, programmers reuse only implementations, whereas with frameworks, they reuse design. A framework embodies the way a family of related programs or pieces of software work. It represents a generic design solution that can be adapted to a variety of specific problems in a given domain. For example, a single framework can embody the way a user interface works, even though two different user interfaces created with the same framework might solve quite different interface problems.

Thus, through the development of frameworks for solutions to various problems and programming tasks, significant reductions in the design and development effort for software can be achieved. A preferred embodiment of the invention utilizes HyperText Markup Language (HTML) to implement documents on the Internet together with a general-purpose secure communication protocol for a transport medium between the client and the Newco. HTTP or other protocols could be readily substituted for HTML without undue experimentation. Information on these products is available in T. Berners-Lee, D. Connoly, "RFC 1866: Hypertext Markup Language--2.0" (November 1995); and R. Fielding, H, Frystyk, T. Berners-Lee, J. Gettys and J. C. Mogul, "Hypertext Transfer Protocol--HTTP/1.1: HTTP Working Group Internet Draft" (May 2, 1996). HTML is a simple data format used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of domains. HTML has been in use by the World-Wide Web global information initiative since 1990. HTML is an application of ISO Standard 8879:1986 Information Processing Text and Office Systems; Standard Generalized Markup Language (SGML).

To date, Web development tools have been limited in their ability to create dynamic Web applications which span from client to server and interoperate with existing computing resources. Until recently, HTML has been the dominant technology used in development of Web-based solutions. However, HTML has proven to be inadequate in the following areas:

Poor performance;

Restricted user interface capabilities;

Can only produce static Web pages;

Lack of interoperability with existing applications and data; and

Inability to scale.

Sun Microsystem's Java language solves many of the client-side problems by:

Improving performance on the client side;

Enabling the creation of dynamic, real-time Web applications; and

Providing the ability to create a wide variety of user interface components.

With Java, developers can create robust User Interface (UI) components. Custom "widgets" (e.g., real-time stock tickers, animated icons, etc.) can be created, and client-side performance is improved. Unlike HTML, Java supports the notion of client-side validation, offloading appropriate processing onto the client for improved performance. Dynamic, real-time Web pages can be created. Using the above-mentioned custom UI components, dynamic Web pages can also be created.

Sun's Java language has emerged as an industry-recognized language for "programming the Internet." Sun defines Java as: "a simple, object-oriented, distributed, interpreted, robust, secure, architecture-neutral, portable, high-performance, multithreaded, dynamic, buzzword-compliant, general-purpose programming language. Java supports programming for the Internet in the form of platform-independent Java applets." Java applets are small, specialized applications that comply with Sun's Java Application Programming Interface (API) allowing developers to add "interactive content" to Web documents (e.g., simple animations, page adornments, basic games, etc.). Applets execute within a Java-compatible browser (e.g., Netscape Navigator) by copying code from the server to client. From a language standpoint, Java's core feature set is based on C++. Sun's Java literature states that Java is basically "C++, with extensions from Objective C for more dynamic method resolution".

Another technology that provides similar function to JAVA is provided by Microsoft and ActiveX Technologies, to give developers and Web designers wherewithal to build dynamic content for the Internet and personal computers. ActiveX includes tools for developing animation, 3-D virtual reality, video and other multimedia content. The tools use Internet standards, work on multiple platforms, and are being supported by over 100 companies. The group's building blocks are called ActiveX Controls, small, fast components that enable developers to embed parts of software in hypertext markup language (HTML) pages. ActiveX Controls work with a variety of programming languages including Microsoft Visual C++, Borland Delphi, Microsoft Visual Basic programming system and, in the future, Microsoft's development tool for Java, code named "Jakarta." ActiveX Technologies also includes ActiveX Server Framework, allowing developers to create server applications. One of ordinary skill in the art readily recognizes that ActiveX could be substituted for JAVA without undue experimentation to practice the invention.

In accordance with a preferred embodiment, BackgroundFinder (BF) is implemented as an agent responsible for preparing an individual for an upcoming meeting by helping him/her retrieve relevant information about the meeting from various sources. BF receives input text in character form indicative of the target meeting. The input text is generated in accordance with a preferred embodiment by a calendar program that includes the time of the meeting. As the time of the meeting approaches, the calendar program is queried to obtain the text of the target event and that information is utilized as input to the agent. Then, the agent parses the input meeting text to extract its various components such as title, body, participants, location, time etc. The system also performs pattern matching to identify particular meeting fields in a meeting text. This information is utilized to query various sources of information on the web and obtain relevant stories about the current meeting to send back to the calendaring system. For example, if an individual has a meeting with Netscape and Microsoft to talk about their disputes, and would obtain this initial information from the calendaring system. It will then parse out the text to realize that the companies in the meeting are "Netscape" and "Microsoft" and the topic is "disputes." Then, the system queries the web for relevant information concerning the topic. Thus, in accordance with an objective of the invention, the system updates the calendaring system and eventually the user with the best information it can gather to prepare the user for the target meeting. In accordance with a preferred embodiment, the information is stored in a file that is obtained via selection from a link imbedded in the calendar system.

Program Organization

A computer program in accordance with a preferred embodiment is organized in five distinct modules: BF.Main, BF.Parse, Background Finder.Error, BF.PatternMatching and BF.Search. There is also a frmMain which provides a user interface used only for debugging purposes. The executable programs in accordance with a preferred embodiment never execute with the user interface and should only return to the calendaring system through Microsoft's Winsock control. A preferred embodiment of the system executes in two different modes which can be specified under the command line sent to it by the calendaring system. When the system runs in simple mode, it executes a keyword query to submit to external search engines. When executed in complex mode, the system performs pattern matching before it forms a query to be sent to a search engine.

Data Structures

The system in accordance with a preferred embodiment utilizes three user defined structures:

1. TMeetingRecord;

2. TPatternElement; and

3. TPatternRecord.

The user-defined structure, tMeetingRecord, is used to store all the pertinent information concerning a single meeting. This info includes userID, an original description of the meeting, the extracted list of keywords from the title and body of meeting etc. It is important to note that only one meeting record is created per instance of the system in accordance with a preferred embodiment. This is because each time the system is spawned to service an upcoming meeting, it is assigned a task to retrieve information for only one meeting. Therefore, the meeting record created corresponds to the current meeting examined. ParseMeetingText populates this meeting record and it is then passed around to provide information about the meeting to other functions. If GoPatternMatch can bind any values to a particular meeting field, the corresponding entries in the meeting record is also updated. The structure of tMeetingRecord with each field described in parentheses is provided below in accordance with a preferred embodiment.

    A.1.1.1.1.1          Public Type tMeetingRecord
    sUserID As String    (user id given by Munin)
    sTitleOrig As String (original non stop listed title we need to keep
                         around to send back to Munin)
    sTitleKW As String   (stoplisted title with only keywords)
    sBodyKW As String    (stoplisted body with only keywords)
    sCompany() As String (companies identified in title or body through
                         pattern matching)
    sTopic() As String   (topics identified in title or body through
                         pattern matching)
    sPeople() As String  (people identified in title or body through
                         pattern matching)
    sWhen() As String    (time identified in title or body through pattern
                         matching)
    sWhere() As String   (location identified in title or body through
                         pattern matching)
    sLocation As String  (location as passed in by Munin)
    sTime As String      (time as passed in by Munin)
    sParticipants() As String (all participants engaged as passed in by
                         Munin)
    sMeetingText As String (the original meeting text w/o userid)
    EndType


There are two other structures which are created to hold each individual pattern utilized in pattern matching. The record tAPatternRecord is an array containing all the components/elements of a pattern. The type tAPatternElement is an array of strings which represent an element in a pattern. Because there may be many "substitutes" for each element, we need an array of strings to keep track of what all the substitutes are. The structures of tAPatternElement and tAPatternRecord are presented below in accordance with a preferred embodiment.
                  Public Type tAPatternElement
                   elementArray() As String
                  End Type
                  Public Type tAPatternRecord
                   patternArray() As tAPatternElement
                  End Type


Common User Defined Constants

Many constants are defined in each declaration section of the program which may need to be updated periodically as part of the process of maintaining the system in accordance with a preferred embodiment. The constants are accessible to allow dynamic configuration of the system to occur as updates for maintaining the code.

Included in the following tables are lists of constants from each module which I thought are most likely to be modified from time to time. However, there are also other constants used in the code not included in the following list. It does not mean that these non-included constants will never be changed. It means that they will change much less frequently.

For Pattern Matching Module (BFPatternMatch): There are no constants in this module which require frequent updates.

General Process Flow

The best way to depict the process flow and the coordination of functions between each other is with the five flowcharts illustrated in FIGS. 2 to 6. FIG. 2 depicts the overall process flow in accordance with a preferred embodiment. Processing commences at the top of the chart at function block 200 which launches when the program starts. Once the application is started, the command line is parsed to remove the appropriate meeting text to initiate the target of the background find operation in accordance with a preferred embodiment as shown in function block 210. A global stop list is generated after the target is determined as shown in function block 220. Then, all the patterns that are utilized for matching operations are generated as illustrated in function block 230. Then, by tracing through the chart, function block 200 invokes GoBF 240 which is responsible for logical processing associated with wrapping the correct search query information for the particular target search engine. For example, function block 240 flows to function block 250 and it then calls GoPatternMatch as shown in function block 260. To see the process flow of GoPattemMatch, we swap to the diagram titled "Process Flow for BF's Pattern Matching Unit."

One key thing to notice is that functions depicted at the same level of the chart are called by in sequential order from left to right (or top to bottom) by their common parent function. For example, Main 200 calls ProcessCommandLinc 210, then CreateStopListist 220, then CreatePatterns 230, then GoBackgroundFinder 240. FIGS. 3 to 6 detail the logic for the entire program, the parsing unit, the pattern matching unit and the search unit respectively. FIG. 6 details the logic determinative of data flow of key information through BackgroundFinder, and shows the functions that are responsible for creating or processing such information.

Detailed Search Architecture Under the Simple

Query Mode

Search Alta Vista

(Function Block 270 of FIG. 2)

The Alta Vista search engine utilizes the identifies and returns general information about topics related to the current meeting as shown in function block 270 of FIG. 2. The system in accordance with a preferred embodiment takes all the keywords from the title portion of the original meeting text and constructs an advanced query to send to Alta Vista. The keywords are logically combined together in the query. The results are also ranked based on the same set of keywords. One of ordinary skill in the art will readily comprehend that a date restriction or publisher criteria could be facilitated on the articles we want to retrieve. A set of top ranking stories are returned to the calendaring system in accordance with a preferred embodiment.

News Page

(Function Block 275 of FIG. 2)

The NewsPage search system is responsible for giving us the latest news topics related to a target meeting. The system takes all of the keywords from the title portion of the original meeting text and constructs a query to send to the NewsPage search engine. The keywords are logically combined together in the query. Only articles published recently are retrieved. The Newspage search system provides a date restriction criteria that is settable by a user according to the user's preference. The top ranking stories are returned to the calendaring system.

FIG. 3 is a user profile data model in accordance with a preferred embodiment. Processing commences at function block 300 which is responsible for invoking the program from the main module. Then, at function block 310, a wrapper function is invoked to prepare for the keyword extraction processing in function block 320. After the keywords are extracted, then processing flows to function block 330 to determine if the delimiters are properly positioned. Then, at function block 340, the number of words in a particular string is calculated and the delimiters for the particular field are and a particular field from the meeting text is retrieved at function block 350. Then, at function block 380, the delimiters of the string are again checked to assure they are placed appropriately. Finally, at function block 360, the extraction of each word from the title and body of the message is performed a word at a time utilizing the logic in function block 362 which finds the next closest word delimiter in the input phrase, function block 364 which strips unnecessary materials from a word and function block 366 which determines if a word is on the stop list and returns an error if the word is on the stop list.

Pattern Matching in Accordance with a Preferred Embodiment

The limitations associated with a simple searching method include the following:

1. Because it relies on a stoplist of unwanted words in order to extract from the meeting text a set of keywords, it is limited by how comprehensive the stoplist is. Instead of trying to figure out what parts of the meeting text we should throw away, we should focus on what parts of the meeting text we want.

2. A simple search method in accordance with a preferred embodiment only uses the keywords from a meeting title to form queries to send to Alta Vista and NewsPage. This ignores an alternative source of information for the query, the body of the meeting notice. We cannot include the keywords from the meeting body to form our queries because this often results in queries which are too long and so complex that we often obtain no meaningful results.

3. There is no way for us to tell what each keyword represents. For example, we may extract "Andy" and "Grove" as two keywords. However, a simplistic search has no way knowing that "Andy Grove" is in fact a person's name. Imagine the possibilities if we could somehow intelligently guess that "Andy Grove" is a person's name. Information such as where he is employed and currently resides.

4. In summary, by relying solely on a stoplist to parse out unnecessary words, we suffer from "information overload".

Pattern Matching Overcomes these Limitations in Accordance with a Preferred Embodiment

Here is how the pattern matching system can address each of the corresponding issues above in accordance with a preferred embodiment.

1. By doing pattern matching, we match up only parts of the meeting text that we want and extract those parts.

2. By performing pattern matching on the meeting body and extracting only the parts from the meeting body that we want. Our meeting body will not go to complete waste then.

3. Pattern matching is based on a set of templates that we specify, allowing us to identify people names, company names and other items from a meeting text.

4. In summary, with pattern matching, we no longer suffer from information overload. Of course, the big problem is how well our pattern matching works. If we rely exclusively on artificial intelligence processing, we do not have a 100% hit rate. We are able to identify about 20% of all company names presented to us.

Patterns

A pattern in the context of a preferred embodiment is a template specifying the structure of a phrase we are looking for in a meeting text. The patterns supported by a preferred embodiment are selected because they are templates of phrases which have a high probability of appearing in someone's meeting text. For example, when entering a meeting in a calendar, many would write something such as "Meet with Bob Dutton from Stanford University next Tuesday." A common pattern would then be something like the word "with" followed by a person's name (in this example it is Bob Dutton) followed by the word "from" and ending with an organization's name (in this case, it is Stanford University).

Pattern Matching Terminology

The common terminology associated with pattern matching is provided below.

Pattern: a pattern is a template specifying the structure of a phrase we want to bind the meeting text to. It contains sub units.

Element: a pattern can contain many sub-units. These subunits are called elements. For example, in the pattern "with $PEOPLE$ from $COMPANY$", "with" "$PEOPLE$" "from" "$COMPANY$" are all elements.

Placeholder: a placeholder is a special kind of element in which we want to bind a value to.Using the above example, "$PEOPLE$" is a placeholder.

Indicator: an indicator is another kind of element which we want to find in a meeting text but no value needs to bind to it. There may be often more than one indicator we are looking for in a certain pattern. That is why an indicator is not an "atomic" type.

Substitute: substitutes are a set of indicators which are all synonyms of each other. Finding any one of them in the input is good.

There are five fields which are identified for each meeting:
        .diamond-solid. Company     ($COMPANY$)
        .diamond-solid. People      ($PEOPLE$)
        .diamond-solid. Location    ($LOCATION$)
        .diamond-solid. Time        ($TIME$)
        .diamond-solid. Topic       ($TOPIC_UPPER$) or ($TOPIC_ALL$)


In parentheses are the placeholders I used in my code as representation of the corresponding meeting fields.

Each placeholder has the following meaning:

$COMPANY$: binds a string of capitalized words (e.g., Meet with Joe Carter of <Andersen Consulting >)

$PEOPLE$: binds series of string of two capitalized words potentially connected by "," "and" or "&" (e.g., Meet with <Joe Carter> of Andersen Consulting, Meet with <Joe Carter and Luke Hughes> of Andersen Consulting)

$LOCATION$: binds a string of capitalized words (e.g., Meet Susan at <Palo Alto Square>)

$TIME$: binds a string containing the format #:## (e.g., Dinner at <6:30 pm>)

$TOPIC_UPPER$: binds a string of capitalized words for our topic (e.g., <Stanford Engineering Recruiting> Meeting to talk about new hires).

$TOPIC_ALL$: binds a string of words without really caring if it's capitalized or not. (e.g., Meet to talk about <ubiquitous computing>)

Here is a table representing all the patterns supported by BF. Each pattern belongs to a pattern group. All patterns within a pattern group share a similar format and they only differ from each other in terms of what indicators are used as substitutes. Note that the patterns which are grayed out are also commented in the code. BF has the capability to support these patterns but we decided that matching these patterns is not essential at this point.

FIG. 4 is a detailed flowchart of pattern matching in accordance with a preferred embodiment. Processing commences at function block 400 where the main program invokes the pattern matching application and passes control to function block 410 to commence the pattern match processing. Then, at function block 420, the wrapper function loops through to process each pattern which includes determining if a part of the text string can be bound to a pattern as shown in function block 430. Then, at function block 440, various placeholders are bound to values if they exist, and in function block 441, a list of names separated by punctuation are bound, and at function block 442 a full name is processed by finding two capitalized words as a full name and grabbing the next letter after a space after a word to determine if it is capitalized. Then, at function block 443, time is parsed out of the string in an appropriate manner and the next word after a blank space in function block 444. Then, at function block 445, the continuous phrases of capitalized words such as company, topic or location are bound and in function block 446, the next word after the blank is obtained for further processing in accordance with a preferred embodiment. Following the match meeting field processing, function block 450 is utilized to locate an indicator which is the head of a pattern, the next word after the blank is obtained as shown in function block 452 and the word is checked to determine if the word is an indicator as shown in function block 454. Then, at function block 460, the string is parsed to locate an indicator which is not at the end of the pattern and the next word after unnecessary white space such as that following a line feed or a carriage return is processed as shown in function block 462 and the word is analyzed to determine if it is an indicator as shown in function block 464. Then, in function block 470, the temporary record is reset to the null set to prepare it for processing the next string and at function block 480, the meeting record is updated and at function block 482 a check is performed to determine if an entry is already made to the meeting record before parsing the meeting record again.

Using the Identified Meeting Fields

Now that we have identified fields within the meeting text which we consider important, there are quite a few things we can do with it. One of the most important applications of pattern matching is of course to improve the query we construct which eventually gets submitted to Alta Vista and News Page. There are also a lot of other options and enhancements which exploit the results of pattern matching that we can add to BF. These other options will be described in the next section. The goal of this section is to give the reader a good sense of how the results obtained from pattern matching can be used to help us obtain better search results.

FIG. 5 is a flowchart of the detailed processing for preparing a query and obtaining information from the Internet in accordance with a preferred embodiment. Processing commences at function block 500 and immediately flows to function block 510 to process the wrapper functionality to prepare for an Internet search utilizing a web search engine. If the search is to utilize the Alta Vista search engine, then at function block 530, the system takes information from the meeting record and forms a query in function blocks 540 to 560 for submittal to the search engine. If the search is to utilize the NewsPage search engine, then at function block 520, the system takes information from the meeting record and forms a query in function blocks 521 to 528.

Alta Vista Search Engine

The strength of the Alta Vista search engine is that it provides enhanced flexibility. Using its advance query method, one can construct all sorts of Boolean queries and rank the search however you want. However, one of the biggest drawbacks with Alta Vista is that it is not very good at handling a large query and is likely to give back irrelevant results. If we can identify the topic and the company within a meeting text, we can form a pretty short but comprehensive query which will hopefully yield better results. We also want to focus on the topics found. It may not be of much merit to the user to find out info about a company especially if the user already knows the company well and has had numerous meetings with them. It's the topics they want to research on.

News Page Search Engine

The strength of the News Page search engine is that it does a great job searching for the most recent news if you are able to give it a valid company name. Therefore when we submit a query to the news page web site, we send whatever company name we can identify and only if we cannot find one do we use the topics found to form a query. If neither one is found, then no search is performed. The algorithmn utilized to form the query to submit to Alta Vista is illustrated in FIG. 7. The algorithmn that we will use to form the query to submit to News Page is illustrated in FIG. 8.

The following table describes in detail each function in accordance with a preferred embodiment. The order in which functions appear mimics the process flow as closely as possible. When there are situations in which a function is called several times, this function will be listed after the first function which calls it and its description is not duplicated after every subsequent function which calls it.
    Procedure
    Name               Type      Called By            Description
    Main               Public    None                 This is the main function
     where the program first launches. It initializes BF with the
    (BF.Main)          Sub                            appropriate parameters
     (e.g., Internet time-out, stoplist. . .) and calls GoBF to launch the
                                                      main part of the program.
    ProcessCommandLine Private   Main                 This function parses the
     command line. It assumes that the delimiter indicating
    (BF.Main)          Sub                            the beginning of imput
     from Munin is stored in the constant CMD_SEPARATOR.
    CreateStopList     Private   Main                 This function sets up a
     stop list for future use to parse out unwanted words from the
    (BF.Main)          Function                       meeting text. There are
     commas on each side of each word to enable straight checking.
    CreatePatterns     Public    Main                 This procedure is called
     once when BF is first initialized to create all the potential
    (BF.Pattern        Sub                            patterns that portions of
     the meeting text can bind to. A pattern can contain however
    Match)                                            many elements as needed.
     There are two types of elements. The first type of elements are
                                                      indicators. These are
     real words which delimit the potential of a meeting field (eg
                                                      company) to follow. Most
     of these indicators are stop words as expected because stop
                                                      words are words usually
     common to all meeting text so it makes sense they form
                                                      patterns. The second type
     of elements are special strings which represent
                                                      placeholders. A
     placeholder is always in the form of $*$ where * can be either
                                                      PEOPLE, COMPANY,
     TOPIC_UPPER, TIME, LOCATION or TOPIC_ALL. A
                                                      pattern can begin with
     either one of the two types of elements and can be however long,
                                                      involving however any
     number/type of elements. This procedure dynamically creates a
                                                      new pattern record for
     each pattern in the table and it also dynamically creates new
                                                      tAPatternElements for
     each element within a pattern. In addition, there is the
                                                      concept of being able to
     substitute indicators within a pattern. For example, the pattern
                                                      $PEOPLE$ of $COMPANY$ is
     similar to the pattern $PEOPLE$ from $COMPANY$.
                                                      "from" is a substitute
     for "of".
                                                      Our structure should be
     able to express such a need for substitution.
    GoBF               Public    Main                 This is a wrapper
     procedure that calls both the parsing and the searching
    (BF.Main)          Sub                            subroutines of the BF. It
     is also responsible for sending data back to Munin.
    ParseMeeting       Public    GoBackGroundFinder   This function takes the
     initial meeting text and identifies the userID
    Text               Function                       of the record as well as
     other parts of the meeting text including the title, body,
    (BF.Parse)                                        participant list,
     location and time. In addition, we call a helper function
                                                      ProcessStopList to
     eliminate all the unwanted words from the originalmeeting title and
                                                      meeting body so that only
     keywords are left. The information parsed out is stored in the
                                                      MeetingRecord structure.
     Note that this function does no error checking and for the most
                                                      time assumes that the
     meeting text string is correctly formatted by Munin.
                                                      The important variable is
     thisMeeting Record is the temp holder for all info regarding
                                                      current meeting.  It's
     eventually returned to caller.
    FormatDelimitation Private   ParseMeetingText,    There are 4 ways in which
     the delimiters can be placed. We take care of all these
    (BF.Parse)                   DetermineNum         cases by reducing them
     down to Case 4 in which there are no delimiters around but
                                 Words,               only between fields in a
     string(e.g., A::B::C)
                                 GetAWordFrom
                                 String
    DetermineNumWords  Public    ParseMeeting         This functions determines
     how many words there are in a string (stInEvalString) The
    (BF.Parse)         Function  Text,                function assumes that
     each word is separated by a designated separator as specified
                                 ProcessStop          in stSeparator. The
     return type is an integer that indicates how many words have been
                                 List                 found assuming each word
     in the string is separated by stSeparator. This function is
                                                      used along with
     GetAWordFromString and should be called before calling
                                                      GetAWordFrom String.
    GetAWordFromString Public    ParseMeeting         This function extracts
     the ith word of the string(stInEvalString)assuming that each
    (BF.Parse)         Function  Text,                word in the string is
     separated by a designated separator contained in the variable
                                 ProcessStop          stSeparator. In most
     cases, use this function with DetermineNumWords. The function
                                 List                 returns the wanted word.
     This function checks to make sure that iInWordNum is within
                                                      bounds  so that i is not
     greater than the total number of words in string or less than/equal
                                                      to zero.  If it is out of
     bounds, we return empty string to indicate we can't get anything.
                                                      We try to make sure this
     doesn't happen by calling DetermineNumWords first.
    ParseAndCleanPhrase Private   ParseMeetingText     This function first
     grabs the word and send it to CleanWord in order strip the stuff that
    (BF.Parse)         Function                       nobody wants. There are
     things in parseWord that will kill the word, so we will need a
                                                      method of looping through
     the body and rejecting words without killing the whole
                                                      function i guess keep
     CleanWord and check a return value ok, now I have a word so
                                                      I need to send it down
     the parse chain. This chain goes ParseCleanPhrase ->
                                                      CleanWord ->
     EvaluateWord. If the word gets through the entire chain without
                                                      being killed, it will be
     added at the end to our keyword string. first would be the function
                                                      that checks for "/" as a
     delimiter and extracts the parts of that. This I will call
                                                      "StitchFace" (Denise is
     more normal and calls it GetAWordFromString) if this finds
                                                      words, then each of these
     will be sent, in turn, down the chain.
                                                      If these get through the
     entire chain without being added or killed then they will be
                                                      added rather than tossed.
    FindMin            Private   ParseAndCleanPhrase  This function takes in 6
     input values and evaluates to see what the minimum non zero
    (BF.Parse)         Function                       value is. It first
     creates an array as a holder so that can sort the five input values
                                                      in ascending order. Thus
     the minimum value will be the first non zero value element
                                                      of the array. If we go
     through entire array without finding a non zero value, we know
                                                      that there is an error
     and we exit the function.
    CleanWord          Private   ParseAndCleanPhrase  This function tries to
     clean up a word in a meeting text. It first of all determines if
    (BF.Parse)         Function                       the string is of a valid
     length. It then passes it through a series of tests to see it is and
                                                      when needed, it will edit
     the word and strip unnecessary characters off of it. Such tests
                                                      includes getting rid of
     file extensions, non chars, numbers etc.
    EvaluateWord       Private   ParseAndCleanPhrase  This function tests to
     see if this word is in the stop list so it can determine
    (BF.Parse)         Function                       whether to eliminate the
     word from the original meeting text. If a word is not in the
                                                      stoplist, it should stay
     around as a keyword and this function exits beautifully with
                                                      no errors. However, if
     the words is a stopword, an error must be returned. We must
                                                      properly  delimit the
     input test string so we don't accidentally retrieve substrings.
    GoPatternMatch     Public    GoBF                 This procedure is called
     when our QueryMethod is set to complex query meaning
    (BF.Pattern        Sub                            we do want to do all the
     pattern matching stuff. It's a simple wrapper function which
    Match)                                            initializes some arrays
     and then invokes pattern matching on the title and the body.
    MatchPatterns      Public    GoPattern Match      This procedure loops
     through every pattern in the pattern table and
    (BF.Pattern        Sub                            tries to identify
     different fields within a meeting text specified by sInEvalString. For
    Match)                                            debugging purposes it
     also tries to tabulate how many times a certain pattern was
                                                      triggered and stores it
     in gTabulateMatches to see which pattern fired the most.
                                                      gTabulateMatches is
     stored as a global because we want to be able to run a batch file
                                                      of 40 or 50 test strings
     and still be able to know how often a pattern was triggered.
    MatchAPattern      Private   MatchPatterns        This function goes
     through each element in the current pattern. It first evaluates to
    (BF.Pattern        Function                       determine whether element
     is a placeholder or an indicator. If it is a placeholder, then it
    Match)                                            will try to bind the
     placeholder with some value. If it is an indicator, then we try to
                                                      locate it. There is a
     trick however. Depending on whether we are at current element is
                                                      the head of the pattern
     or not we want to take different actions. If we are at the head,
                                                      we want to look for the
     indicator or the placeholder. If we can't find it, then we
                                                      know that the current
     pattern doesn't exist and we quit. However, if it is not
                                                      the head, then we
     continue looking,  because there may still be a head somewhere.
                                                      We retry in this case.
    etingField         Private   MatchAPattern        This function uses a big
     switch statement to first determine what kind of placeholder we
    (BF.Pattern        Function                       are talking about and
     depending on what type of placeholder, we have specific
    Match)                                            requirements and
     different binding criteria as specified in the subsequent functions
                                                      called such as BindNames,
     BindTime etc. If binding is successful we add it to our


guessing record. BindNames Private MatchMeetingField In this function, we try to match names to the corresponding placeholder $PEOPLE$. (BF.Pattern Function Names are defined as any consecutive two words which are capitalized. We also what Match) to retrieve a series of names which are connected by and, or & so we look until we don't see any of these 3 separators anymore. Note that we don't want to bind single word names because it is probably too general anyway so we don't want to produce broad but irrelevant results. This function calls BindAFullName which binds one name so in a since BindNames collects all the results from BindAFullName BindAFullName Private BindNames This function tries to bind a full name. If the $PEOPLE$ placeholder is not the head (BF.Pattern Function of the pattern, we know that it has to come right at the beginning of the test string Match) because we've been deleting stuff off the head of the string all along. If it is the head, we search until we find something that looks like a full name. If we can't find it, then there's no such pattern in the text entirely and we quit entirely from this pattern. This should eventually return us to the next pattern in MatchPatterns. GetNextWordAfter- Private BindAFull This function grabs the next word in a test string. It looks for the next word after white WhiteSpace Function Name, spaces, @ or/. The word is defined to end when we encounter another one of these (BF.Pattern BindTime, white spaces or separators. Match) BindCompanyTo picLoc BindTime Private MatchMeetingField Get the immediate next word and see if it looks like a time pattern. If so we've found a (BF.Pattern Function time and so we want to add it to the record. We probably should add more time patterns Match) But people don't seem to like to enter the time in their titles these days especially since we now have tools like OutLook BindCompany- Private MatchMeetingField This function finds a continuous capitalized string and binds it to stMatch which is TopicLoc Function passed by reference from MatchMeetingField. A continuous capitalized string is a (BF.Pattern sequence of capitalized words which are not interrupted by things like, . etc. Match) There's probably more stuff we can add to the list of interruptions. LocatePatternHead Private MatchAPattern This function tries to locate an element which is an indicator. Note that this indicator (BF.Pattern Function SHOULD BE AT THE HEAD of the pattern otherwise it would have gone to the Match) function LocateIndicator instead. Therefore, we keep on grabbing the next word until either there's no word for us to grab (quit) or if we find one of the indicators we are looking for. ContainInArray Private LocatePattern `This function is really simple. It loops through all the elements in the array `to find (BF.Pattern Function Head. a matching string. Match) LocateIndicator LocateIndicator Private MatchAPattern This function tries to locate an element which is an indicator. Note that this indicator is (BF.Pattern Function NOT at the head of the pattern otherwise it would have gone to LocatePatternHead Match) instead. Because of this, if our pattern is to be satisfied, the next word we grab HAS to be the indicator or else we would have failed. Thus we only grab one word, test to see if it is a valid indicator and then return result. InitializeGuess- Private MatchAPattern This function reinitializes our temporary test structure because we have already Record Sub transferred the info to the permanent structure, we can reinitialize it so they each (BF.Pattern have one element Match) AddToMeeting- Private MatchAPattern This function is only called when we know that the information stored in Record Sub tInCurrGuesses is valid meaning that it represents legitimate guesses of meeting fields (BF.Pattern ready to be stored in the permanent Match) record, tInMeetingRecord. We check to make sure that we do not store duplicates and we also what to clean up what we want to store so that there's no clutter such as punctuation, etc. The reason why we don't clean up until now is to save time. We don't waste resources calling ParseAndCleanPhrase until we know for sure that we are going to add it permanently. NoDuplicate Private AddToMeetingRecord This function loops through each element in the array to make sure that the test string Entry Function aString is not the same as any of the strings already stored in the array. Slightly different (BF.Pattern from ContainInArray. Match) SearchAltaVista Public GoBackGroundFinder This function prepares a query to be submitted to AltaVista Search engine. It submits it (BF.Search) Function and then parses the returning result in the appropriate format containing the title, URL and body/summary of each story retrieved. The number of stories retrieved is specified by the constant NUM_AV.sub.-- STORIES. Important variables include stURLAltaVista used to store query to submit stResultHTML used to store html from page specified by stURLAltaVista. ConstructAlta- Private SearchAltaVista This function constructs the URL string for the alta vista search engine using the VistaURL Function advanced query search mode. It includes the keywords to be used, the language and (BF.Search) how we want to rank the search. Depending on whether we want to use the results of our pattern matching unit, we construct our query differently. ConstructSimple Private ConstructAltaVistaURL This function marches down the list of keywords stored in the stTitleKW or stBodyKW KeyWord Function ConstructNewsPageURL fields of the input meeting record and links them up into one string with each keyword (BF.Search) separated by a connector as determined by the input variable stInConnector. Returns this newly constructed string. ConstructComplex- Private ConstructAltaVistaURL This function constructs the keywords to be send to the AltaVista site. Unlike AVKeyWord Function ConstructSimpleKeyWord which simply takes all the keywords from the title to form (BF.Search) the query, this function will look at the results of BF`s pattern matching process and see if we are able to identify any specific company names or topics for constructing the queries. Query will include company and topic identified and default to simple query if we cannot identify either company or topic. JoinWithConnectors Private ConstructComplex- This function simply replaces the spaces between the words within the string with a (BF.Search) Function AVKeyWord, connector which is specified by the input. ConstructComplex- NPKeyWord, RefineWithRank RefineWithDate Private ConstructAltaVistaURL This function constructs the date portion of the alta vista query and returns this portion of (NOT CALLED Function the URL as a string. It makes sure that alta vista searches for articles within the past AT THE PAST_NDAYS. MOMENT) (BF.Search) RefineWithRank Private ConstructAltaVistaURL This function constructs the string needed to passed to Altavista in order to rank an (BF.Search) Function advanced query search. If we are constructing the simple query we will take in all the keywords from the title. For the complex query, we will take in words from company and topic, much the same way we formed the query in ConstructComplexAVKeyWord IdentifyBlock Public SearchAltaVista, This function extracts the block within a string marked by the beginning and the ending (BF.Parse) Function SearchNewsPage tag given as inputs starting at a certain location (iStart). The block retrieved does not include the tags themselves. If the block cannot be identified with the specified delimiters, we return unsuccessful through the parameter iReturnSuccess passed to use by reference. The return type is the the block retrieved. IsOpenURLError Public SearchAltaVista, This function determines whether the error encountered is that of a timeout error. It (BF.Error) Function SearchNewsPage restores the mouse to default arrow and then returns true if it is a time out or false otherwise. SearchNews Public GoBackGroundFinder This function prepares a query to be submitted to NewsPage Search engine. It submits it Page Function and then parses the returning result in the appropriate format containing the title, (BF.Search) URL and body/summary of each story retrieved. The number of stories retrieved is specified by the constant UM_NP_STORIES ConstructNews- Private SearchNewsPage This function constructs the URL to send to the NewsPage site. It uses the information PageURL Function contained in the input meeting record to determine what keywords to use. Also (BF.Search) depending whether we want simple or complex query, we call different functions to form strings. ConstructComplex- Private ConstructNewsPageURL This function constructs the keywords to be send to the NewsPage site. Unlike NPKeyWord Function ConstructKeyWordString which simply takes all the keywords from the title to form (BF.Search) the query, this function will look at the results of BF's pattern matching process and see if we are able to identify any specific company names or topics for constructing the queries. Since newspage works best when we have a company name, we'll use only the company name and only if there is no company will we use topic. ConstructOverall- Private GoBackGroundFinder This function takes in as input an array of strings (stInStories) and a MeetingRecord Result Function which stores the information for the current meeting. Each element in the array stores (BF.Main) the stories retrieved from each information source.

The function simply constructs the appropriate output to send to Munin including a return message type to let Munin know that it is the BF responding and also the original user_id and meeting title so Munin knows which meeting BF is talking about. ConnectAnd Public GoBackGroundFinder This function allows Background Finder to connect to Munin and eventually transport TransferTo Sub information to Munin. We will be using the UDP protocol instead of the TCP protocol so Munin we have to set up the remote host and port correctly. We use a global string to store (BF.Main) gResult Overall because although it is unnecessary with UDP, it is needed with TCP and if we ever switch back don't want to change code. DisconnectFrom- Public MuninAndQuit Sub (BF.Main)


FIG. 6 is a flowchart of the actual code utilized to prepare and submit searches to the Alta Vista and Newspage search engines in accordance with a preferred embodiment. Processing commences at function block 610 where a command line is utilized to update a calendar entry with specific calendar information. The message is next posted in accordance with function block 620 and a meeting record is created to store the current meeting information in accordance with function block 630. Then, in function block 640 the query is submitted to the Alta Vista search engine and in function block 650, the query is submitted to the Newspage search engine. When a message is returned from the search engine, it is stored in a results data structure as shown in function block 660 and the information is processed and stored in summary form in a file for use in preparation for the meeting as detailed in function block 670.

FIG. 7 provides more detail on creating the query in accordance with a preferred embodiment. Processing commences at function block 710 where the meeting record is parsed to obtain potential companies, people, topics, location and a time. Then, in function block 720, at least one topic is identified and in function block 720, at least one company name is identified and finally in function block 740, a decision is made on what material to transmit to the file for ultimate consumption by the user.

FIG. 8 is a variation on the query theme presented in FIG. 7. A meeting record is parsed in function block 800, a company is identified in function block 820, a topic is identified in function block 830 and finally in function block 840 the topic and or the company is utilized in formulating the query.

Alternative embodiments for adding various specific features for specific user requirements are discussed below.

Enhance Target Rate for Pattern Matching

To increase BF's performance, more patterns/pattern groups are added to the procedure "CreatePatterns." The existing code for declaring patterns can be used as a template for future patterns. Because everything is stored as dynamic arrays, it is convenient to reuse code by cutting and pasting. The functions BindName, BindTime, BindCompanyLocTopic which are responsible for associating a value with a placeholder can be enhanced. The enhancement is realized by increasing the set of criteria for binding a certain meeting field in order to increase the number of binding values. For example, BindTime currently accepts and binds all values in the form of ##:## or #:##. To increase the times we can bind, we may want BindTime to also accept the numbers 1 to 12 followed by the more aesthetic time terminology "o'clock," Vocabulary based recognition algorithms and assigning an accuracy rate to each guess BF makes allowing only guesses which meet a certain threshold to be valid.

Depending on what location the system identifies through pattern matching or alternatively depending on what location the user indicates as the meeting place, a system in accordance with a preferred embodiment suggests a plurality of fine restaurants whenever it detects the words lunch/dinner/breakfast. We can also use a site like company finder to confirm what we got is indeed a company name or if there is no company name that pattern matching can identify, we can use a company finder web site as a "dictionary" for us to determine whether certain capitalized words represent a company name. We can even display stock prices and breaking news for a company that we have identified.

Wireless Bargain Identification in Accordance with a Preferred Embodiment

FIG. 9 is a flow diagram that depicts the hardware and logical flow of control for a device and a software system designed to allow Web-based comparison shopping in conventional, physical, non-Web retail environments. A wireless phone or similar hand-held wireless device 920 with Internet Protocol capability is combined with a miniature barcode reader 910 (installed either inside the phone or on a short cable) and used to scan the Universal Product Code (UPC) bar code on a book or other product 900. The wireless device 920 transmits the bar code via an antennae 930 to the Pocket BargainFinder Service Module (running on a Web server) 940, which converts it to (in the case of books) its International Standard Book Number or (in the case of other products) whatever identifier is appropriate. The Service Module then contacts the appropriate third-party Web site(s) to find price, shipping and availability information on the product from various Web suppliers 950. This information is formatted and displayed on the hand-held device's screen. The IP wireless phone or other hand held device 920 utilizes a wireless modem such as a Ricochet SE Wireless Modem from Metricom. Utilizing this device, a user can hang out in a coffee shop with a portable computer perched on a rickety little table, with a latte sloshing dangerously close to the keyboard, and access the Internet at speeds rivaling direct connect via a telephone line.

The 8-ounce Ricochet SE Wireless Modem is about as large as a pack of cigarettes and setup is extremely simple, simply attach the modem to the back of your portable's screen with the included piece of Velcro, plug the cable into the serial port, flip up the stubby antenna, and transmit. Software setup is equally easy: a straightforward installer adds the Ricochet modem drivers and places the connection icon on your desktop. The functional aspects of the modem are identical to that of a traditional telephone modem.

Of course, wireless performance isn't nearly as reliable as a traditional dial-up phone connection. We were able to get strong connections in several San Francisco locations as long as we stayed near the windows. But inside CNET's all-brick headquarters, the Ricochet couldn't connect at all. When you do get online, performance of up to 28.8 kbps is available with graceful degradation to slower speeds. But even the slower speeds didn't disappoint. Compared to the alternative--connecting via a cellular modem--the Ricochet is much faster, more reliable, and less expensive to use. Naturally, the SE Wireless is battery powered. The modem has continuous battery life of up to 12 hours. And in accordance with a preferred embodiment, we ran down our portable computer's dual cells before the Ricochet started to fade.

Thus, utilizing the wireless modem, a user may utilize the web server software 940 to identify the right product 950 and then use an appropriate device's key(s) to select a supplier and place an order in accordance with a preferred embodiment. The BargainFinder Service Module then consummates the order with the appropriate third-party Web supplier 960.

mySite! Personal Web Site & Intentions Value Network Prototype

mySite! is a high-impact, Internet-based application in accordance with a preferred embodiment that is focused on the theme of delivering services and providing a personalized experience for each customer via a personal web site in a buyer-centric world. The services are intuitively organized around satisfying customer intentions--fundamental life needs or objectives that require extensive planning decisions, and coordination across several dimensions, such as financial planning, healthcare, personal and professional development, family life, and other concerns. Each member owns and maintains his own profile, enabling him to create and browse content in the system targeted specifically at him. From the time a demand for products or services is entered, to the completion of payment, intelligent agents are utilized to conduct research, execute transactions and provide advice. By using advanced profiling and filtering, the intelligent agents learn about the user, improving the services they deliver. Customer intentions include Managing Daily Logistics (e.g., email, calendar, contacts, to-do list, bill payment, shopping, and travel planning); and Moving to a New Community (e.g., finding a place to live, moving household possessions, getting travel and shipping insurance coverage, notifying business and personal contacts, learning about the new community). From a consumer standpoint, mySite! provides a central location where a user can access relevant products and services and accomplish daily tasks with ultimate ease and convenience.

From a business standpoint, mySite! represents a value-added and innovative way to effectively attract, service, and retain customers. Intention value networks allow a user to enter through a personalized site and, and with the assistance of a learning, intelligent agent, seamlessly interact with network participants. An intention value network in accordance with a preferred embodiment provides superior value. It provides twenty four hour a day, seven days a week access to customized information, advice and products. The information is personalized so that each member views content that is highly customized to assure relevance to the required target user.

Egocentric Interface

An Egocentric Interface is a user interface crafted to satisfy a particular user's needs, preferences and current context. It utilizes the user's personal information that is stored in a central profile database to customize the interface. The user can set security permissions on and preferences for interface elements and content. The content integrated into the Egocentric Interface is customized with related information about the user. When displaying content, the Egocentric Interface will include the relationship between that content and the user in a way that demonstrates how the content relates to the user. For instance, when displaying information about an upcoming ski trip the user has signed up for, the interface will include information about events from the user's personal calendar and contact list, such as other people who will be in the area during the ski trip. This serves to put the new piece of information into a context familiar to the individual user.

FIG. 10A describes the Intention Value Network Architecture implementation for the World Wide Web. For simplification purposes, this diagram ignores the complexity pertaining to security, scalability and privacy. The customer can access the Intention Value Network with any Internet web browser 1010, such as Netscape Navigator or Microsoft Internet Explorer, running on a personal computer connected to the Internet or a Personal Digital Assistant with wireless capability. See FIG. 17 for a more detailed description of the multiple methods for accessing an Intention value Network. The customer accesses the Intention Value Network through the unique name or IP address associated with the Integrator's Web Server 1020. The Integrator creates the Intention Value Network using a combination of resources, such as the Intention Database 1030, the Content Database 1040, the Supplier Profile Database 1050, and the Customer Profile Database 1060.

The Intention Database 1030 stores all of the information about the structure of the intention and the types of products and services needed to fulfill the intention. Information in this database includes intention steps, areas of interest, layout templates and personalization templates. The Content Database 1040 stores all of the information related to the intention, such as advice, referral information, personalized content, satisfaction ratings, product ratings and progress reports.

The Supplier Profile Database 1050 contains information about the product and service providers integrated into the intention. The information contained in this database provides a link between the intention framework and the suppliers. It includes product lists, features and descriptions, and addresses of the suppliers' product web sites. The Customer Profile Database 1060 contains personal information about the customers, such as name, address, social security number and credit card information, personal preferences, behavioral information, history, and web site layout preferences. The Supplier's Web Server 1070 provides access to all of the supplier's databases necessary to provide information and transactional support to the customer.

The Product Information Database 1080 stores all product-related information, such as features, availability and pricing. The Product Order Database 1090 stores all customer orders. The interface to this database may be through an Enterprise Resource Planning application offered by SAP, Baan, Oracle or others, or it may be accessible directly through the Supplier's Web Server or application server. The Customer Information Database 1091 stores all of the customer information that the supplier needs to complete a transaction or maintain customer records.

FIG. 10B is a flowchart providing the logic utilized to create a web page within the Egocentric Interface. The environment assumes a web server and a web browser connected through a TCP/IP network, such as over the public Internet or a private Intranet. Possible web servers could include Microsoft Internet Information Server, Netscape Enterprise Server or Apache. Possible web browsers include Microsoft Internet Explorer or Netscape Navigator. The client (i.e. web browser) makes a request 1001 to the server (i.e. web server) for a particular web page. This is usually accomplished by a user clicking on a button or a link within a web page. The web server gets the layout and content preferences 1002 for that particular user, with the request to the database keyed off of a unique user id stored in the client (i.e. web browser) and the User profile database 1003. The web server then retrieves the content 1004 for the page that has been requested from the content database 1005. The relevant user-centric content, such as calendar, email, contact list, and task list items are then retrieved 1006. (See FIG. 11 for a more detailed description of this process.) The query to the database utilizes the user content preferences stored as part of the user profile in the User profile database 1003 to filter the content that is returned. The content that is returned is then formatted into a web page 1007 according to the layout preferences defined in the user profile. The web page is then returned to the client and displayed to the user 1008.

FIG. 11 describes the process of retrieving user-centric content to add to a web page. This process describes 1006 in FIG. 10B in a more detailed fashion. It assumes that the server already has obtained the user profile and the existing content that is going to be integrated into this page. The server parses 1110 the filtered content, looking for instances of events, contact names and email addresses. If any of these are found, they are tagged and stored in a temporary holding space. Then, the server tries to find any user-centric content 1120 stored in various databases.

This involves matching the tagged items in the temporary storage space with calendar items 1130 in the Calendar Database 1140; email items 1115 in the Email Database 1114; contact items 1117 in the Contact Database 1168; task list items 1119 in the Task List Database 1118; and news items 1121 in the News Database 1120. After retrieving any relevant user-centric content, it is compiled together and returned 1122.

User Persona

The system allows the user to create a number of different person as that aggregate profile information into sets that are useful in different contexts. A user may create one persona when making purchases for his home. This persona may contain his home address and may indicate that this user is looking to find a good bargain when shopping. The same user may create a second persona that can be used when he is in a work context. This persona may store the user's work address and may indicate that the user prefers certain vendors or works for a certain company that has a discount program in place. When shopping for work-related items, the user may use this persona. A persona may also contain rules and restrictions. For instance, the work persona may restrict the user to making airline reservations with only one travel agent and utilizing booking rules set up by his employer.

FIG. 12 describes the relationship between a user, his multiple person as and his multiple profiles. At the User Level is the User Profile 1200. This profile describes the user and his account information. There is one unique record in the database for each user who has an account. Attached to each user are multiple Personas 1220, 1230 & 1240. These Personas are used to group multiple profiles into useful contexts. For instance, consider a user who lives in San Francisco and works in Palo Alto, but has a mountain cabin in Lake Tahoe. He has three different contexts in which he might be accessing his site. One context is work-related. The other two are home-life related, but in different locations. The user can create a Persona for Work 1220, a Persona for Home 1230, and a Persona for his cabin home 1240. Each Persona references a different General Profile 1250, 1260 and 1270 which contains the address for that location. Hence, there are three General Profiles. Each Persona also references one of two Travel Profiles. The user maintains a Work Travel Profile 1280 that contains all of the business rules related to booking tickets and making reservations. This Profile may specify, for instance, that this person only travels in Business or First Class and his preferred airline is United Airlines. The Work Persona references this Work Travel Profile. The user may also maintain a Home Travel Profile 1290 that specifies that he prefers to travel in coach and wants to find non-refundable fairs, since they are generally cheaper. Both the Persona for Home and the Persona for the cabin home point to the Home Travel Profile.

FIG. 13 describes the data model that supports the Persona concept. The user table 1310 contains a record for each user who has an account in the system. This table contains a username and a password 1320 as well as a unique identifier. Each user can have multiple Personas 1330, which act as containers for more specialized structures called Profiles 1340. Profiles contain the detailed personal information in Profile Field 1350 records. Attached to each Profile are sets of Profile Restriction 1360 records. These each contain a Name 1370 and a Rule 1380, which define the restriction. The Rule is in the form of a pattern like (if x then y), which allows the Rule to be restricted to certain uses. An example Profile Restriction would be the rule that dictates that the user cannot book a flight on a certain airline contained in the list. This Profile Restriction could be contained in the "Travel" Profile of the "Work" Persona set up by the user's employer, for instance. Each Profile Field also contains a set of Permissions 1390 that are contained in that record. These permissions dictate who has what access rights to that particular Profile Field's information.

Intention-Centric Interface

Satisfying Customer Intentions, such as Planning for Retirement or Relocating requires a specialized interface. Customer Intentions require extensive planning and coordination across many areas, ranging from financial security, housing and transportation to healthcare, personal and professional development, and entertainment, among others. Satisfying Intentions requires a network of complementary businesses, working across industries, to help meet consumers' needs.

An Intention-Centric Interface is a user interface designed to help the user manage personal Intentions. At any given point, the interface content is customized to show only content that relates to that particular Intention. The Intention-Centric Interface allows the user to manage the process of satisfying that particular Intention. This involves a series of discrete steps and a set of content areas the user can access. At any point, the user can also switch the interface to manage a different Intention, and this act will change the content of the interface to include only that content which is relevant to the satisfaction of the newly selected Intention.

FIG. 14 provides a detailed description of the data model needed to support an Intention-Centric Interface. Each User Persona 1410 (see FIG. 13 for a more detailed description of the Persona data model.) has any number of active User Intentions 1420. Each active User Intention is given a Nickname 1430, which is the display name the user sees on the screen. Each active User Intention also contains a number of Data Fields 1440, which contain any user data collected throughout the interaction with the user. For instance, if the user had filled out a form on the screen and one of the fields was Social Security Number, the corresponding Data Field would contain Name="SSN" 1450, Value="999-99-9999" 1460. Each User Intention also keeps track of Intention Step 1470 completion status. The Completion 1480 field indicates whether the user has completed the step. Every User Intention is a user-specific version of a Generic Intention 1490, which is the default model for that Intention for all users. The Generic Intention is customized through Custom Rules 1411 and 1412 that are attached to the sub-steps in the Intention. These Custom Rules are patterns describing how the system will customize the Intention for each individual user using the individual user's profile information.

Statistical Agent

An agent keeps track of key statistics for each user. These statistics are used in a manner similar to the Tamagochi virtual reality pet toy to encourage certain behaviors from the user. The statistics that are recorded are frequency of login, frequency of rating of content such as news articles, and activity of agents, measured by the number of tasks which it performs in a certain period. This information is used by the system to emotionally appeal to the user to encourage certain behaviors.

FIG. 15 describes the process for generating the page that displays the agent's current statistics. When the user requests the agent statistics page 1510 with the client browser, the server retrieves the users' statistics 1520 from the users' profile database 1530. The server then performs the mathematical calculations necessary to create a normalized set of statistics 1540. The server then retrieves the formulas 1550 from the content database 1560 that will be used to calculate the user-centric statistics. Graphs are then generated 1570 using the generic formulas and that user's statistics. These graphs are inserted into a template to create the statistics page 1580.

Personalized Product Report Service

The system provide Consumer Report-like service that is customized for each user based on a user profile. The system records and provides ratings from users about product quality and desirability on a number of dimensions. The difference between this system and traditional product quality measurement services is that the ratings that come back to the users are personalized. This service works by finding the people who have the closest match to the user's profile and have previously rated the product being asked for. Using this algorithm will help to ensure that the product reports sent back to the user only contain statistics from people who are similar to that user.

FIG. 16 describes the algorithm for determining the personalized product ratings for a user. When the user requests a product report 1610 for product X, the algorithm retrieves the profiles 1620 from the profile database 1630 (which includes product ratings) of those users who have previously rated that product. Then the system retrieves the default thresholds 1640 for the profile matching algorithm from the content database 1650. It then maps all of the short list of users along several dimensions specified in the profile matching algorithm 1660. The top n (specified previously as a threshold variable) nearest neighbors are then determined and a test is performed to decide if they are within distance y (also specified previously as a threshold variable) of the user's profile in the set 1670 using the results from the profile matching algorithm. If they are not within the threshold, then the threshold variables are relaxed 1680, and the test is run again. This processing is repeated until the test returns true. The product ratings from the smaller set of n nearest neighbors are then used to determine a number of product statistics 1690 along several dimensions. Those statistics are inserted into a product report template 1695 and returned to the user 1697 as a product report.

Personal Profile and Services Ubiquity

This system provides one central storage place for a person's profile. This storage place is a server available through the public Internet, accessible by any device that is connected to the Internet and has appropriate access. Because of the ubiquitous accesibility of the profile, numerous access devices can be used to customize services for the user based on his profile. For example, a merchant's web site can use th is profile to provide personalized content to the user. A Personal Digital Assistant (PDA) with Internet access can synchronize the person's calendar, email, contact list, task list and notes on the PDA with the version stored in the Internet site. This enables the person to only have to maintain one version of this data in order to have it available whenever it is needed and in whatever formats it is needed.

FIG. 17 presents the detailed logic associated with the many different methods for accessing this centrally stored profile. The profile database 1710 is the central storage place for the users' profile information. The profile gateway server 1720 receives all requests for profile information, whether from the user himself or merchants trying to provide a service to the user. The profile gateway server is responsible for ensuring that information is only given out when the profile owner specifically grants permission. Any device that can access the public Internet 1730 over TCP/IP (a standard network communications protocol) is able to request information from the profile database via intelligent HTTP requests. Consumers will be able to gain access to services from devices such as their televisions 1740, mobile phones, Smart Cards, gas meters, water meters, kitchen appliances, security systems, desktop computers, laptops, pocket organizers, PDAs, and their vehicles, among others. Likewise, merchants 1750 will be able to access those profiles (given permission from the consumer who owns each profile), and will be able to offer customized, personalized services to consumers because of th
