Research mode for a knowledge base search and retrieval system
First Claim
1. A method for processing a query in a search and retrieval system, said method comprising the steps of:
- generating a plurality of point of view gists for at least one document, wherein each point of view gist comprises a synopsis of a corresponding document with a slant toward a topic, so that said plurality of point of view gists for a single document comprise synopses with slants toward a plurality of different topics;
processing a query, which includes at least one query term, to identify a plurality of topics related to said query; and
selecting a plurality of point of view gists from one or more documents to generate, in response to said query, a new research document, wherein said point of view gists selected comprise synopses with slants toward said topics related to said query.

Abstract
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 view gists, based on the document themes, that have a slant towards the topics related to the query. A knowledge base, which includes categories arranged hierarchically, is configured as a directed graph to links those categories having a lexical, semantic or usage association. Through use of the knowledge base, an expanded set of query terms are generated, and research documents are compiled that include point of view gists relevant to the expanded set of query terms. A content processing system, which identifies the themes for a document and classifies the document themes in categories of the knowledge base, is also disclosed.

8. A method for processing a query in a search and retrieval system, said method comprising the steps of:
-
processing a query, which includes a plurality of query terms, to identify a plurality of topics related to said query; selecting a plurality of documents relevant to said query; and generating, in response to said query, a new research document comprising portions of different documents of said documents selected, wherein each portion selected for said research document satisfies a different topic related to said query so as to infer a response to said query through use of multiple documents.
