Information retrieval system providing secondary content analysis on collections of information objects

摘要

An information retrieval system having a secondary content analysis engine for use on collections of documents. Such collections of documents dynamically arise as a result of queries one or more, possibly distal, information sources. The secondary content analysis engine resides on an Information Access client computer system and allows the user to: 1) iteratively refine queries in more powerful ways than typically supported by relevance feedback or other query modification methods, 2) browse a medium-sized collection of documents (on the order of 1000 items) in more effective ways than is traditionally possible or 3) obtain more information for increasing user understanding of the collection.
