AN ENVIRONMENT FOR REUSING ONTOLOGIES WITHIN A KNOWLEDGE ENGINEERING APPROACH

Domain models can be constructed more easily and made more robust by r eusing ontologies in a well-defined way. In this paper the KARO approa ch is introduced which provides various means of retrieving and adapti ng components of an ontology as part of a domain model construction pr ocess. KARO is based on the knowledge-processing component LILOG-KR pr ovided by the LILOG text-understanding system. Above all, the notion o f classification is applied for the retrieval of relevant categories. The upper structure of LILOG-KB serves as an exemplary ontology. By in tegrating KARO into the Model-based and Incremental Knowledge Engineer ing Environment (MIKE) the reuse of a predefined ontology can be integ rated into the development process of expert systems in a systematic w ay.
