Schönegge: Inverse Verification of Problem-Solving Methods

Abstract. Context dependency of knowledge models brings with it several problems: the unreliability of knowledge-based systems, maintenance costs, and limitations on sharing and reuse. Problem-solving methods are knowledge models of the reasoning process of knowledge-based systems. In this paper we present a method called inverse verification to deal with the context dependency of problem-solving methods. Inverse verification investigates the context dependency of a method by making underlying assumptions explicit. It uses failed proof attempts as a search method for assumptions and an analysis of these failures for constructing and refining assumptions
