OntoCAPE - a large-scale ontology for chemical process engineering

Abstract:
An overview on OntoCAPE, a large-scale ontology for chemical process engineering, is given, and the development and some applications of OntoCAPE are reported. The methodology adopted in developing OntoCAPE is described to show how the ontology has evolved from its skeletal, informal specification to a complete, formal specification. Furthermore, the organization of the ontology is addressed through presenting a modular, layered structure that involves five layers of different degrees of abstraction. This design allows a proper balance between usability and reusability, and provides a principled guidance for understanding and further developing this ontology. Applications of OntoCAPE in a few areas in computer-aided process engineering are sketched. Concerning the handling of the changes of such a complex engineering ontology in a long period of evolution, advantageous features of OntoCAPE are discussed, and a comprehensive environment providing adequate computer support to the evolution of complex ontologies is envisioned.
