摘要： The embodiments of the invention provide methods for obtaining improved text similarity measures. More specifically, a method of measuring similarity between at least two electronic documents begins by identifying similar terms between the electronic documents. This includes basing similarity between the similar terms on patterns, wherein the patterns can include word patterns, letter patterns, numeric patterns, and/or alphanumeric patterns. The identifying of the similar terms also includes identifying multiple pattern types between the electronic documents. Moreover, the basing of the similarity on patterns identifies terms within the electronic documents that are within a category of a hierarchy. Specifically, the identifying of the terms reviews a hierarchical data tree, wherein nodes of the tree represent terms within the electronic documents. Lower nodes of the tree have specific terms; and, wherein higher nodes of the tree have general terms.

摘要： A local database cache enabling persistent, adaptive caching of either full or partial content of a remote database is provided. Content of tables comprising a local cache database is defined on per-table basis. A table is either: defined declaratively and populated in advance of query execution, or is determined dynamically and asynchronously populated on-demand during query execution. Based on a user input query originally issued against a remote DBMS and referential cache constraints between tables in a local database cache, a Janus query plan, comprising local, remote, and probe query portions is determined. A probe query portion of a Janus query plan is executed to determine whether up-to-date results can be delivered by the execution of a local query portion against a local database cache, or whether it is necessary to retrieve results from a remote database by executing a remote query portion of Janus query plan.

摘要： A system and method for automatically discovering topical structures of databases includes a model builder adapted to compute various kinds of representations for the database based on schema information and data values of the database. A plurality of base clusterers is also provided, one for each representation. Each base clusterer is adapted to perform, for the representation, preliminary topical clustering of tables within the database to produce a plurality of clusters, such that each of the clusters corresponds to a set of tables on the same topic. A meta-clusterer aggregates results of the clusterers into a final clustering, such that the final clustering comprises a plurality of the clusters. A representative finder identifies representative tables from the clusters in the final clustering. The representative finder identifies at least one representative table for each of the clusters in the final clustering. The representative finder also arranges the representative tables by topic as a topical directory and outputs the topical directory.

摘要： A computer-implemented method for accessing content items in a content store are described. In one embodiment, the computer-implemented method includes maintaining a text index of content items in a content store to enable a keyword search on the content items, receiving a query having a keyword and generating a hit list from the text index using the keyword, and extracting frequent phrases from text within content items of the hit list. The computer-implemented method also includes assigning a relative relevance to the frequent phrases and grouping content items into topics based on presence of relevant phrases within the content items of the hit list. The hit list includes one or more content items of the content store. The frequent phrases having a relatively high relevance are relevant phrases.
