    Abstract
    The conference was attended by about 150 people involved in 31 participating groups. Its goal was to bring research groups together to discuss their work on a new large test 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 had been 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

    Abstract
    The first Text Retrieval Conference (TREC-1) was held in early November and was attended by about 100 people working in the 25 participating groups. The goal of the conference was to bring research gropus together to discuss their work on a new large test collection. There was a large variety of retrieval techniques reported on, including methods using automatic thesauri, sophisticated term weighting, natural language techniques, relevance feedback, and advanced pattern matching. As results had been run through a common evaluation package, groups were able to compare the effectiveness of different techniques, and discuss how differences among the systems affected performance
