E X P E R T S Y S T E M C O N S T R U C T I O N K I T The knowledge independent LISP-based expert system called PORTAL is now available for distribution from the Laboratory for Computer Enhanced Cognition, University of Victoria. It is a simple rule-based system, with a forward inference mechanism, and includes supporting utilities for a rule and entity editor as well as some analytical tools for validating your knowledge base. The system has been written in Franz LISP under UNIX 4.1 BSD, and can be obtained on a non-commercial, non-disclosure, as-is basis for a nominal fee. The distributed version includes source and executable code, and a MAKE system for implementation. We are offering this system in the interests of making a simple but complete expert system construction tool available to research laboratories, so that the difficult problems of knowledge acquisition can be attacked on a broad front. The fee is $200.00 for universities, and $500.00 for other laboratories. Interested parties should send a purchase order for the amount indicated, or call.
