Design of ontology in Semantic Web engineering process

Semantic Web (SW) is an extension of current web in which web information resources are accompanied with their formal semantics, understandable by machine. The ontology is the recommended mechanism by W3C for these formal semantics and it is considered as a backbone of every SW application. Its design is remained lack of attention during engineering process of SW applications. In this paper we propose a technique for ontology design during SW application engineering process. By incorporating this technique, existing web applications design methods may easily be upgraded for SW applications. We illustrate proposed technique using a case study, formalize resultant specification it in OWL standards through ontology development tool Protege, and then validate it using W3C online ontology validation service.
