Title

Query evaluation : strategies and optimizations

Source

Information processing and management. 31(1995) no.6, S.831-850

Year

1995

Abstract

Discusses the 2 major query evaluation strategies used in large text retrieval systems and analyzes the performance of these strategies. Discusses several optimization techniques that can be used to reduce evaluation costs and present simulation results to compare the performance of these optimization techniques when evaluating natural language queries with a collection of full text legal materials
