Abstract
The present invention is directed toward an improved method of mining data. The method uses a query composed of natural language text that may be expanded to include related terms and concepts. The query is parsed into a variety of textual elements that may be keywords, phrases, or concepts, and compared with one or more databases to determine what, if any, information units in the database are related to textual elements that have been culled from the query.
