Concept knowledge base search and retrieval system
First Claim
1. A method for processing queries in a search and retrieval system, said method comprising the steps of:
- storing a knowledge base comprising a plurality of categories, wherein said categories depict subject matter used for classification of information in said search and retrieval system;
processing a query, which includes at least one query term, to identify categories of said knowledge base relevant to said at least one query term; and
displaying, in response to said query, said categories relevant to said at least one query term, wherein said categories displayed provide a profile of subject matter relevant to said query that shows how information, organized in said search and retrieval system, relates to said query.

Abstract
A knowledge base search and retrieval system, which includes factual knowledge base queries and concept knowledge base queries, is disclosed. A knowledge base stores associations among terminology/categories that have a lexical, semantical or usage association. Document theme vectors identify the content of documents through themes as well as through classification of the documents in categories that reflects what the documents are primarily about. The factual knowledge base queries identify, in response to an input query, documents relevant to the input query through expansion of the query terms as well as through expansion of themes. The concept knowledge base query does not identify specific documents in response to a query, but specifies terminology that identifies the potential existence of documents in a particular area.
