The Effectiveness of the Thesaurus Method in Automatic Information Retrieval. Technical Report No. 75-261.
Yu, C. T.; Salton, G.
Formal proofs are given of the effectiveness under well-defined conditions of the thesaurus method in information retrieval. It is shown, in particular, that when certain semantically related terms are added to the information queries originally submitted by the user population, a superior retrieval system is obtained in the sense that for every level of the recall the retrieval precision is at least as good for the altered queries as for the original one.
