A Vector Space Model for Automatic Indexing

by: Gerard Salton, Anita Wong, and Chung-Shu Yang

In: Communications of the ACM, Vol. 18, Nr. 11 (1975) , p. 613--?620.

Abstract

In a document retrieval, or other pattern matching environment where stored entities documents are compared with each other or with incoming patterns search requests, it appears that the best indexing property space is one where each entity lies as far away from the others as possible; in these circumstances the value of an indexing system may be expressible as a function of the density of the object space; in particular, retrieval performance may correlate inversely with space density. An approach based on space density computations is used to choose an optimum indexing vocabulary for a collection of documents. Typical evaluation results are shown, demonstating the usefulness of the model.
