On the perils of merging boolean and weighted retrieval systems

A. Bookstein

Journal of the American Society for Information Science, 1978, vol. 29, issue 3, 156-158

Abstract: Attempts have been made to rank the output of a Boolean search in terms of the overlap of index terms in the request and document. As attractive as the merger of two approaches may seem, a closer examination reveals disturbing ambiguities, with equivalent Boolean expressions yielding different weights for the retrieval documents. An alternative approach is suggested.
