Extending a knowledge base to support explanations

Abstract

In order to support explanations in a knowledge-based system, a method is proposed to extend an existing knowledge base: adding more knowledge and including relations and their semantics among the different types of knowledge. The criterion followed to organize a knowledge base is to classify and represent knowledge according to different levels of application and abstraction. This criterion also facilitates future extension of a knowledge base for explanations of the procedure and heuristic knowledge.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
