abstract = {A great many automatic indexing methods have been
implemented and evaluated over the last few years, and automatic
procedures comparable in effectiveness to conventional manual ones are
now easy to generate. Two drawbacks of the available automatic indexing
methods are the absence of reliable linguistic inputs during the
indexing process and the lack of formal, analytical proofs concerning
the effectiveness of the proposed methods. The precision weighting
procedure described in the present study uses relevance criteria to
weight the terms occurring in user queries as a function of the balance
between relevant and nonrelevant documents in which these terms occur;
this approximates a semantic know-how of term importance. Formal
mathematical proofs are given under well-defined conditions of the
effectiveness of the method.},
