Psyxpert: an expert system prototype for aiding psychiatrists in the diagnosis of psychotic disorders.
Psyxpert is an expert computer system prototype designed to aid psychiatrists in the diagnosis of mental disorders, in cases where psychotic features are the prominent part of the presenting clinical picture. The knowledge base contains psychiatric knowledge in the form of production rules. The system uses a backward-chaining control strategy to guide the consultation. Psyxpert provides a menu-driven user interface and an explanation subsystem. The system uses certainty and importance measures to produce a diagnosis with an attached certainty factor and recommendations for further evaluation or therapy. Psyxpert is written in Virginia Tech HC Prolog and runs on Digital Equipment Corporation's VAX 11/780 under the VMS operating system.
