摘要

The third Text REtrieval Conference (TREC-3) was held in Gaithersburg, Maryland,November 2-4, 1994 and was attended by 150 people involved in the 33 participating groups. The goal of the Conference was to bring research groups together to discuss their work on a new large text collection. There was a large variation of retrieval techniques reported on, including methods using automatic thesauri, sophisticated term weighting, natural language techniques, relevance feedback, and advanced pattern matching. As results were run through a common evaluation package, groups were able to compare the effectiveness of different techniques, and discuss how differences between the systems affected performance.
