How do we augment the user query?

  • Manual thesaurus

    • E.g. MedLine: physician, syn: doc, doctor, MD, medico

    • Can be query rather than just synonyms

  • Global Analysis: (static; of all documents in collection)

    • Automatically derived thesaurus

      • (co-occurrence statistics)

    • Refinements based on query log mining

      • Common on the web

  • Local Analysis: (dynamic)

    • Analysis of documents in result set
