Abstract:
1. A processor-implemented method of finding related documents within a set of documents in response to a query containing search terms, comprising: generating overlapping vectors to represent a document in the set of documents, wherein each vector is centered on each word in the document and represents a local environment for said each word; wherein said each word around which a vector is generated is excluded from the local environment for said each word; using vectors generated for the set of documents to build context-dependent probability models based on a statistical analysis for predicting related documents and related terms; based on the query and using the probability models, searching for a first set of related documents that are relevant to the search terms in the query; using the probability models, automatically searching for related terms that are relevant to the search terms in the query; and using the related terms, automatically searching for a second set of documents that are relevant to the related terms.
