Abstract
A system and method for identifying semantically relevant documents is provided. An index having semantic index key terms from one or more documents is maintained. A query is obtained and semantic key terms of the query are identified. Each of the query key terms are associated with information, including use of the word and a grammatical role of the word. Each of the query key terms and variants of the query key terms is looked up in the index based on the information. One or more of the documents in the index are identified as possible relevant candidates based on the look up. A potential match candidate set is generated by filtering the possible relevant candidates. At least one of the documents that match the query is identified by comparing a semantic representation for each non-filtered potential match candidate in the set with a semantic representation for the query.
