A library of problem-solving components based on the integration of the search paradigm with task and method ontologies

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 atask ontology. Then we instantiate a generic model o...

Description
Summary: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 atask ontology. Then we instantiate a generic model of problem solving assearchin 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 ofontology/method specializationandconfiguration. 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 ofparametric design.
