Abstract

In this paper we investigate the reuse of tasks and problem-solving methods and we propose a model of how to organize a library of reusable components for knowledge-based systems. In our approach, we first describe a class of problems by means of a task ontology. Then we instantiate a generic model of problem solving as search in terms of the concepts in the task ontology, to derive a task-specific, but method-independent, problem-solving model. Individual problem-solving methods can then be (re-)constructed from the generic problem-solving model through a process of ontology/method specialization and configuration. The resulting library of reusable components enjoys a clear theoretical basis and has been tested successfully on a number of applications. In the paper, we illustrate the approach in the area of parametric design.
