Problems in modeling a weighted Boolean retrieval system
Donald H. Kraft, W.G. Waller · OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) · 1979
The use of weights to denote a query representation and/or the indexing of a document is analyzed as a generalization of a Boolean retrieval system. Criteria are given for the functions used to evaluate the relevance of the records to a specific query. Various mechanisms for evaluating the relevance of records with regard to a given query are tested and found to be less than satisfactory. A new approach is suggested to avoid some of the perils.
