A research mode in a search and retrieval system generates a research document that infers an answer to a query from multiple documents. The search and retrieval system includes point of view gists for documents to provide a synopsis for a corresponding document with a slant toward a topic. To generate a research document, the search and retrieval system processes a query to identify one or more topics related to the query, selects document themes relevant to the query, and then selects point of...

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...

A theme parsing system that determines the thematic context of input discourse is disclosed. Each word used in a language carries thematic information that conveys the importance of the meaning and content of the discourse. The theme parsing system discriminates words and phrases of the input discourse, identifying the type of importance or meaning, the impact on different parts of the discourse, and the overall contribution to the content of the discourse. The thematic conext of the discourse i...

A content processing system determines the content of input discourse. The content processing system includes a lexicon, which contains definitional characteristics for words and terms, and a knowledge catalog. The knowledge catalog provides independent and parallel static ontologies to accurately represent a broad coverage of concepts that define knowledge. The knowledge catalog also includes a dynamic level for expanding concepts in the static ontologies. A theme parsing system determines the ...

A knowledge catalog includes a plurality of independent and parallel static ontologies to accurately represent a broad coverage of concepts that define knowledge. The actual configuration, structure and orientation of a particular static ontology is dependent upon the subject matter or field of the ontology in that each ontology contains a different point of view. The static ontologies store all senses for each word and concept. A knowledge classification system, that includes the knowledge cata...
