Abstract
Proceedings of the 4th TREC-Conference held in Gaithersburg, MD, Nov 1-3, 1995. Aim of the conference was discussion on retrieval techniques for large trest collections. different research groups used different techniques, such as automatic thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief descriptions including timing and storage information
