Abstract: Disclosed are methods and systems for indexing or retrieving materials accessible through computer networks.

Abstract: Systems and methods described herein can assign a confidence score to a match of unstructured descriptive information with structured reference information in a reference database. The systems and methods can take into account the structured nature of the reference information in assigning the score, thereby facilitating increased confidence in the match, and consequently, facilitating improved database organization and content identification.

Abstract: Disclosed is a method and device and computer storage medium for determining whether two pages linked on the World Wide Web are a part of the same World Wide Web site. The method involves examining and comparing the IP addresses of the Web pages, and can also be extended to finding other pages to which a given Web page is linked on the Web, and to determining whether a Web page of interest is part of a Web site with a desired characteristic, such as being part of an electronic commerce site.

Abstract: Systems and methods for facilitating higher confidence matches are provided. In one embodiment, a system includes a memory that stores computer executable components, and a microprocessor that executes the computer executable components stored in the memory. The components can include a metadata matching component that determines a metadata match level between metadata of a plurality of files, and a thresholding component. The thresholding component may compare a metadata threshold with the metadata match level and output a signal configured to cause a decrease in a melody matching strength threshold from a first value to a second value based at least on the metadata match level being greater than the metadata threshold.

Abstract: Disclosed are methods and systems for automatically assigning index terms to electronic documents such as Web pages or sites in a manner which may be used to facilitate the retrieval of electronic documents of interest. The method involves determining co-occurrences of terms in other documents with the electronic document, and selecting terms as index terms based upon those scores. The method permits the efficient retrieval of electronic documents.

Abstract: Disclosed is a method and device for selecting documents, such as Web pages or sites, for presentation to a user, in response to a user expression of interest, during the course of presentation to the user of a document, such as a video or audio selection, whose content varies with time. The method takes advantage of information retrieval techniques to select documents related to the portion of the temporal document in which the user has expressed interest. The method generates the search query to use to select documents by reference to text associated with the portion of the temporal document in which the user has expressed interest, as by using the closed caption test associated with the video, or by using speech recognition techniques. The method further uses a weighting function to weigh the terms used in the search query, depending on their temporal relationship to the user expression of interest.

Abstract: Disclosed are methods and systems for selecting electronic documents, such as Web pages or sites, from among documents in a collection, based upon the occurrence of selected terms in segments of the documents. The method may be applied where index terms have previously been assigned to the documents. The method may be used to select supercategories of banner advertisements from which to choose an advertisement to display for a user.

Abstract: Disclosed is a method and device for storing information about Web documents such as pages or sites in a manner which may be used in conjunction with inverted term lists to facilitate the retrieval of documents of interest from the Web. The method involves constructing compressed surrogates for documents, such that various operations may be performed without the need to retrieve a copy of the document from the Web. The method permits the efficient updating of inverted term lists when documents on the Web have been modified or deleted, and also permits the efficient processing of search queries in a variety of circumstances.

Abstract: A method for detecting incorrect categorization of data includes obtaining a database containing a plurality of entry-category pairs, calculating a score for each entry-category pair that corresponds to a likelihood that the pair contains an incorrect category assignment, and verifying the correctness of the assignment based on the score. The verification step can be conducted manually. The score assists users in focusing any manual verification efforts on data that may actually contain incorrect category assignments, thereby making the verification process more efficient. The method can be used to review and correct business name and phone number listings in telephone directories.
