Learning assistance expert system based on Java production system with a self-adaptive function

This paper proposes a new production system (PS) with a self-adaptive function based on the Java language, in order to realize a knowledge-base (KB) development environment featuring platform independence and no requirement for special software tools. This new PS, called Adaptive Java Production System (A-JPS) in this paper also features a user profile evaluation mechanism using a causal network (CN) allowing general DAG structures. By means of experiments using an experimental learning assistance KB based on A-JPS, it is demonstrated that the proposed self-adaptation method is effective.
