Title

Condorcet Query Engine : a query engine for coordinated index terms

Source

Abstract

On-line information retrieval systems often offer their users some means to tune the query to match the level of granularity of the information request. Users can be offered a far greater range of possibilities, however, if documents are indexed with coordinated index concepts. Coordinated index concepts are compound index concepts that function as simple subject descriptores, as in 'cures (headache, aspirin)'. We show the point by giving a functional specification of a query engine that can handle both simple and coordinated index concepts, Boolean combinations, and superconcept expansion. The Condorcet Query Engine, a prototype query engine that can be run over the WWW, demonstrates the feasibility of these ideas. The combination of known and novel techniques ensures a smooth migration path from existing query engines to more advanced engines that handle coordinated index concepts
