TL;DR: In this paper, a method and system organize and retrieve information using taxonomies, a document classifier, and an autocontextualizer, where documents are transformed from clear text into a structured record and automatically constructed indexes help identify when the structured record is an appropriate response to a query.
Abstract: A method and system organize and retrieve information using taxonomies, a document classifier, and an autocontextualizer. Documents (or other knowledge containers) in an organization and retrieval subsystem may be manually or automatically classified into taxonomies. Documents are transformed from clear text into a structured record. Automatically constructed indexes help identify when the structured record is an appropriate response to a query. An automatic term extractor creates a list of terms indicative of the documents' subject matter. A subject matter expert identifies the terms relevant to the taxonomies. A term analysis system assigns the relevant terms to one or more taxonomies, and a suitable algorithm is then used to determine the relatedness between each list of terms and its associated taxonomy. The system then clusters documents for each taxonomy in accordance with the weights ascribed to the terms in the taxonomy's list and a directed acyclic graph (DAG) structure is created.

TL;DR: In this paper, a method and system for retrieving information through the use of a multi-stage interaction with a client to identify particular knowledge content associated with a knowledge map is described.
Abstract: A method and system are disclosed for retrieving information through the use of a multi-stage interaction with a client to identify particular knowledge content associated with a knowledge map. The present invention is an application program running on a server accessed via the world-wide web or other data network using standard Internet protocols, a web browser and web server software. In addition to an automated portion, the present invention allows a human dialog designer to model the way the system elicits information, giving a human feel to the dialog and a better customer experience. In operation, users start a dialog by directing their web browser to a designated web page. This web page asks the user some initial questions that are then passed to a dialog engine. The dialog engine then applies its methods and algorithms to a knowledge map, using dialog control information\ and the user's responses to provide feedback to the user. The feedback may include follow-up questions, relevant documents, and instructions to the user (e.g., instructions to contact a human customer service representative). This dialog engine response is rendered as a web page and returned to the user's web browser. The user can then respond further to the follow-up questions he or she is presented, and the cycle repeats. The invention can be implemented so that it can interact with customers through a wide variety of communication channels including the Internet, wireless devices (e.g., telephone, pager, etc.), handheld devices such as a Personal Data Assistant (PDA), email, and via a telephone where the automated system is delivered using an interactive voice response (IVR) and/or speech-recognition system.

TL;DR: In this article, the concepts are organized in primary groups, such as Activities, Objects, Symptoms, and Products groups, which may be implemented as taxonomies, and a list of links or other document indicators tagged to the matched concepts is displayed for the user.
Abstract: This document discusses, among other things, systems, devices, and methods for implementing an efficient and cost-effective automated content provider that effectively steers a user to relevant stored documents. Word or text features are extracted from user query language, and matched to substantially similar concept features. The concepts are organized in primary groups, such as Activities, Objects, Symptoms, and Products groups, which may be implemented as taxonomies. Documents that include the concept feature are tagged to that concept. A list of links or other document indicators tagged to the matched concepts is displayed for the user. Derived groups map relationships between concepts in the same or different primary groups, so that a particular matched concept results in the display of related concepts for restricting or otherwise changing the documents in play that are displayed for the user. This document also describes techniques for ranking the related concepts for display to the user.

TL;DR: In this article, a visual search experience editor for providing a tailored search experience to one or more end-users is described, where the editor provides a What-YouSee-Is-What-You-Get (WYSIWIG)-type interface, so that an administrative user can see what the tailored search environment will look like to the end-user.
Abstract: This document describes, among other things, a visual search experience editor for providing a tailored search experience to one or more end-users. In certain examples, the editor provides a What-You-See-Is-What-You-Get (WYSIWIG)-type interface, so that an administrative user can see what the tailored search experience will look like to the end-user. This may include the ability to review live search results or other specialized transaction interface results responsive to the tailored search. This document also describes various techniques of triggering tailored search experiences, as well as techniques for mapping queries to tailored search experiences, such as to generalize a particular tailored search for a particular query to apply to other similar queries.

TL;DR: In this paper, a method and system for organizing and retrieving information through the use of taxonomies is described, where documents stored in the organization and retrieval subsystem may be manually or automatically classified into a predetermined number of taxonomic categories.
Abstract: A method and system are disclosed for organizing and retrieving information through the use of taxonomies. Documents stored in the organization and retrieval subsystem may be manually or automatically classified into a predetermined number of taxonomies. In operation, automatic term extractor creates a list of terms that are indicative of the subject matter contained in the documents. A term analysis system assigns the relevant terms to one or more taxonomies, and a suitable algorithm is then used to determine the relatedness between each list of terms and its associated taxonomy. The system then clusters documents for each taxonomy in accordance with the weights ascribed to the terms in the taxonomy's list and a directed acyclic graph (DAG) hierarchical structure is created. The present invention may then be used to aid a researcher or user in quickly identifying relevant documents, in response to an inputted query.

TL;DR: In this article, the authors present an integrated implementation framework and resulting medium for knowledge retrieval, management, delivery and presentation, which includes a first server component responsible for adding and maintaining domain-specific semantic information and a second server component that hosts semantic and other knowledge for use by the first component that work together to provide context and time-sensitive semantic information retrieval services.
Abstract: The present invention is directed to an integrated implementation framework and resulting medium for knowledge retrieval, management, delivery and presentation. The system includes a first server component that is responsible for adding and maintaining domain-specific semantic information and a second server component that hosts semantic and other knowledge for use by the first server component that work together to provide context and time-sensitive semantic information retrieval services to clients operating a presentation platform via a communication medium. Within the system, all objects or events in a given hierarchy are active Agents semantically related to each other and representing queries (comprised of underlying action code) that return data objects for presentation to the client according to a predetermined and customizable theme. This system provides various means for the client to customize and “blend” Agents and the underlying related queries to optimize the presentation of the resulting information.

TL;DR: In this paper, a flowchart-based approach is used to build a logical structure for a customer relationship management (CRM) system, which comprises an ordered set of questions and branching logic that are presented to a customer of the business when the customer contacts the business with an inquiry.
Abstract: A flowchart-based tool can be used to build a logical structure. In the context of a customer relationship management (CRM) system, the logical structure can comprise an ordered set of questions and branching logic that are presented to a customer of the business when the customer contacts the business with an inquiry, such as for a sale or service inquiry or other interaction. An engine can run a session associated with the logical structure, with the session presenting questions, text, graphics, and the like dynamically to customer across a network, such as the Internet and a web site. Branching logic determines the appropriate information to present to the user based on answers to previous questions. The engine allows presentation of the information to the user/customer, by generating hypertext markup language (HTML) files to display the questions or other elements of the logical structure as part of a user interface on a client terminal of the customer.
