摘要： An apparatus for searching a document collection is provided. The apparatus includes a memory, which is arranged to store a plurality of documents that are respectively associated with one or more categories and contain terms, a search processor, which is arranged to provide an index of the terms indicating the documents in which the terms appear, to estimate a first statistical distribution of each of at least some of the terms in the index over the documents in the collection, to estimate a second statistical distribution of each of at least some of the categories over the documents in the collection, to accept a query comprising one or more of the terms and a specified category restriction referring to at least one of the categories, to compute a local term distribution, which is indicative of occurrence frequencies of at least one of the terms in the query within the specified category restriction, using the first and second estimated statistical distributions to determine a category-specific score for the at least one of the terms responsively to the local term distribution within the specified category restriction, and to apply the query to the index using the category-specific score so as to return a response, wherein the processor is arranged to construct term histograms of the at least some of the terms in the index, to construct category histograms of the at least some of the categories, and to map the documents in the collection to bins of the histograms, so as to estimate the first and second statistical distributions, and wherein the processor is arranged to determine a category restriction histogram based on the category histogram of the at least one of the categories responsively to the category restriction, and to multiply the category restriction histogram by the term histogram of the at least one of the terms in the query so as to produce a localized term histogram.

摘要： 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).

摘要： A system and method including a simulator operating in conjunction with a search-engine, for improving document and site findability. Users input their content (pages or sites) and the simulator will analyze the site in terms of structure and content. It will then give the user a ranked list of suggestions about how the user might improve his/her site's findability. The user will then be able to apply some or all of these suggestions, or any other changes, by virtually modifying the site, and then immediately receive feedback both on how the pages look and a sense of the degree of findability improvement. The interactive process allows users to simulate modifications in their site structure and content in order to improve its findability. When the user completes the modifications and is satisfied with the new findability of his site, the user will be able then to replace his/her current site in the repository with the modified one.
