Home - What is Prolog+CG 2.0?
Prolog+CG 2.0 is an implementation in Java of standard Prolog, but with extensions for handling the Conceptual Graph theory of John Sowa. Object-Oriented extensions are also provided. CGs are first-class data structures, allowing easy reasoning about CGs. Ontologies are also supported.
Prolog+CG 2.0 is legacy code. A newer, better version has been developed by Prof. Dr. Adil Kabbaj, the original author of Prolog+CG. This new version is included in the Amine-platform. This website is dedicated to maintaining the legacy version, but please consider using the newer version instead.
See "What is Prolog+CG 2.0?" for more information.
