Abstract:
A method for generating query feedback terminology in an information retrieval system, said method comprising the steps of:storing a plurality of query feedback terms identified through a plurality of documents for use as query feedback in said information retrieval system;generating a plurality of co-occurrence signatures for each query feedback term in a set of said query feedback terms, wherein a co-occurrence signature comprises a plurality of entries, such that each entry depicts a co-occurrence distance between two query feedback terms as they appear in said documents, wherein said signatures depict patterns of semantic distance among said different query feedback terms;processing said signatures to reduce a number of said entries in said signature while preserving said co-occurrence distance characteristic among said signatures;selecting, as query feedback, query feedback terms with co-occurrence signatures that compare with co-occurrence signatures of said query term in a predetermined manner; anddisplaying said query feedback terms as at least a partial response to said query.
