Extended Boolean query processing in the Generalized Vector Space
Model.

Information Systems. Vol. 14, no. 1, pp. 47-63. 1989
An information retrieval model, named the Generalized Vector Space
Model (GVSM), is extended to handle situations where queries are
specified as weighted Boolean expressions. It is shown that this
unified model, unlike currently available alternatives, has the
advantage of incorporating term correlations into the retrieval
process. The query language extension is attractive in the sense
that most of the algebraic properties of the strict Boolean
language are still preserved. Although the experimental results
for the proposed extended Boolean retrieval are not always better
than the vector processing method, the developments here are
significant in facilitating commercially available retrieval
systems to benefit from the vector based methods.
