LONG-TERM QUERY REFINEMENT SYSTEM

摘要

A system for providing long term query refinement. Low level information may be stored based on user feedback. There may be equivalence classes in an archive or memory which contain items from a query search which are labeled positive or negative by a user. Labels may be stored in class pairs over previously run queries. There may be propagation of labels to other items in the same or other classes. There may be a refinement which aids in changing the query to one that indicates more accurately what the user wants. A result set of items may be formulated from which a user may select a new query.
