ABSTRACT
A knowledge base search and retrieval system, which
includes factual knowledge base queries and concept knowl edge 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 classi?cation of the documents in categories that re?ects 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 speci?c documents in response to a query, but
speci?es terminology that identi?es the potential existence of documents in a particular area.
