An infamation retrieval model, named the Generaliied Vectm Spice Model (GVSM). is extended m handle situations where queries are specitied as (extended) Boolean expressions. It is shown tbat this unified model, unlike currently available alternatives, has the advantage of inwrpating tetm cortelations inm the retrieval process. 'Ilte query language extension is attractive in the sense that most of the aIgebraic properties of tbe strict Boolean language are still preserved. Although the
more » ... al results for extended Boolean retrieval are not always better than the vector processing method, the developments here am signiecant in facilitating commercially available retrieval systems to benefit from the vector based methods. The proposed scheme is compared m the pnorm model advanced by Salmn snd coworkers. An important conclusion is that it is desirable m investigate further extensions that can offer the benefits of both proposals.
