KNOWLEDGE ENGINEERING - PRINCIPLES AND METHODS

This paper gives an overview of the development of the field of Knowle dge Engineering over the last 15 years. We discuss the paradigm shift from a transfer view to a modeling view and describe two approaches wh ich considerably shaped research in Knowledge Engineering: Role-limiti ng Methods and Generic Tasks. To illustrate various concepts and metho ds which evolved in recent years we describe three modeling frameworks : CommonKADS, MIKE and PROTEGE-II. This description is supplemented by discussing some important methodological developments in more detail: specification languages for knowledge-based systems, problem-solving methods and ontologies. We conclude by outlining the relationship of K nowledge Engineering to Software Engineering, Information Integration and Knowledge Management.
