  • MindServer Searches Smarter Network World Fusion, June 18 2002 by Jason Meserve
    Describes the search and retrieval engine, using the example of the multiple meanings of the word "Java". Quotes CEO as saying that information management is one problem, so the company does not break it up into search, taxonomy, categorization and recommendations. Personalization, by tracking individual usage and group membership, can improve relevance rankings. Users can have topics for search results as well as the automatic categories, and the system can incorporate external data such as the MESH thesaurus for the National Library of Medicine.
