The invention is a method for textual searching of text-based databases including databases of compiled internet content, scientific literature, abstracts for books and articles, newspapers, journals, and the like. Specifically, the algorithm supports searches using full-text or webpage as query and keyword searches allowing multiple entries and an information-content based ranking system (Shannon Information score) that uses p-values to represent the likelihood that a hit is due to random matches. Additionally, users can specify the parameters that determine hits and their ranking with scoring based on phrase matches and sentence similarities.

Full text query and search systems and methods of use

A system (125) identifies a document and obtains one or more types of history data associated with the document. The system (125) may generate a score for the document based, at least in part, on the one or more types of history data.

Information retrieval based on historical data

A method analyzes the visual content of media such as videos for collecting together visually-similar appearances in their constituent images (e.g. same scenes, same objects, faces of the same people.) As a result, the most relevant and salient (of clearest and largest presence) visual appearances depicted in the videos are presented to the user, both for the sake of summarizing the video content for the users to “see before they watch” (that is, judge by the depicted video content in a filmstrip-like summary whether they want to mouse-click on the video and actually spend time watching it), as well as for allowing to users to further refine their video search result set according to the most relevant and salient video content returned (e.g. largest screen-time faces).

Apparatus and software system for and method of performing a visual-relevance-rank subsequent search

A system and method involves detecting operational social disruptive events on a global scale, assigning disease event staging and warnings to express data in more simplistic terms, modeling data in conjunction with linguistics analysis to establish responsive actions, generating visualization and modeling capabilities for communicating information, and modeling disease propagation for containment and forecasting purposes.

A data-driven, hierarchical information search and navigation system and method enable search and navigation of sets of documents or other materials by certain common attributes that characterize the materials. The search and navigation system of the present invention includes features of an navigation interface, a search interface, a knowledge base and a taxonomy definition process and a classification process for generating the knowledge base, a graph-based navigable data structure and method for generating the data structure. A data-driven, hierarchical information search and navigation system and method enable this navigation mode by cociating terms with the materials, defining a set of hierarchical relationships mong the terms, providing a guided navigation mechanism based on the relationship between the terms, and providing a guided navigation mechanism that can respond to free-text queries with single-term or multi-term interpretations.

Disclosed is a system architecture, components and a searching technique for an Unstructured Information Management System (UIMS). The UIMS may be provided as middleware for the effective management and interchange of unstructured information over a wide array of information sources. The architecture generally includes a search engine, data storage, analysis engines containing pipelined document annotators and various adapters. The searching technique makes use of a two-level searching technique. A search query includes a search operator containing of a plurality of search sub-expressions each having an associated weight value. The search engine returns a document or documents having a weight value sum that exceeds a threshold weight value sum. The search operator is implemented as a Boolean predicate that functions as a Weighted AND (WAND).

PROBLEM TO BE SOLVED: To provide system architecture, component, and search technique for unstructured information management system (UIMS). SOLUTION: The UIMS can be provided as middleware for effective management and exchange of unstructured information relating to a wide range of arrays of information sources. The architecture generally comprises a search engine, a data recording area, an analysis engine including pipelined document annotators, and various adaptors. The search technique utilizes two-level retrieval process. Search query include a search operator having a plurality of search sub-expressions each having an associated weight value. The search engine returns one or more documents having a weight value sum exceeding a threshold weight value sum. The search operator is implemented as a Boolean predicate which functions as weighted AND(WAND). COPYRIGHT: (C)2005,JPO&NCIPI

System, method, and computer program recording medium for performing unstructured information management and automatic text analysis

PROBLEM TO BE SOLVED: To provide a device for performing a method for pruning an index of a corpus of text documents. SOLUTION: The method includes steps for ranking the postings in the index (50) and pruning from the index the postings below a given level in the ranking (48). The given level is set based on a parameter received from a user and the rank thereof so that the top of results returned using a reverse index before pruning is similar to the top of results returned using the reverse index after pruning.
