Abstract
Problem solving methods (PSM's) are important in constructing modular and reusable knowledge-based systems, as they specify the different types of knowledge used in knowledge-based reasoning, as well as under what circumstances what knowledge is to be applied. We argue that the formal modeling of PSM's is a useful means for clarifying, communicating and comparing problem-solving knowledge. This paper shows how such PSM's can be formally defined. We illustrate this by developing a formal model for the Cover- and-Differentiate method for diagnosis, and comparing this to Heuristic Classification.
The research reported here was carried out in the course of the REFLECT (P 3178) and the KADS-II (P 5248) projects. These projects are partially funded by the ESPRIT Basic Research resp. ESPRIT-II Programmes of the Commission of the European Communities. The partners in the REFLECT project are the University of Amsterdam (Amsterdam, The Netherlands), the Netherlands Energy Research Foundation ECN (Petten, The Netherlands), the National German Research Centre for Computer Science GMD (St. Augustin, Germany) and BSR Consulting (Munich, West-Germany). The partners in the KADS-II project are Cap Gemini Innovation (Paris, France), Cap Gemini Logic (Stockholm, Sweden), the Netherlands Energy Research Foundation ECN (Petten, The Netherlands), Entel (Madrid, Spain), IBM France (Paris, France), Lloyds' Register (Croydon, United Kingdom), the Swedish Institute of Computer Science (Stockholm, Sweden), Siemens AG (Munich, Germany), Touche Ross MC (London, UK), the University of Amsterdam (Amsterdam, The Netherlands) and the Free University of Brussels (Brussels, Belgium). This paper reflects the opinions of the authors and not necessarily those of the consortia.
