Abstract

An expert system has been extended to a kind of expertext system and can be used to structure a query to a medical literature system and retrieve document citations. The expert system is built on the ROIS expert system shell, and the literature retrieval is from the Excerpta Medica document database EMBASE. The domain knowledge in ROIS is structured in a rich but small semantic net, while EMBASE has a massive, hierarchical, semantic net backbone. Queries that reason with the patient record and a medical semantic net so as to produce Boolean queries for literature retrieval have been implemented. The terms of these queries are then mapped into the semantic net of EMBASE. Finally, another reasoning strategy ranks documents to the query.
