Title

Boolean mapping algorithms across heterogeneous information sources

Source

Journal of the China Society for Scientific and Technical Information. 17(1998) no.3, S.185-189

Abstract

Notes the difficulties of searching over heterogeneous information sources where query languages are not unifrom. Presents a model where Boolean queries are composed in one rich front end language. For each query and target source, the query is transformed into a subsuming query that can be supported by the source but may return extra documents. The results are then processed by a filter query to yield the correct results
