Abstract | Implementation of relevance feedback explored here demonstrates feasibility of query reformulation for boolean retrievals from online databases. Improvements to a term prevalence formula used in earlier research are presented, along with experimental results that confirm crucial role of term weights in relevance feedback. Seven references are cited. (Author/EJS) |
