Formal Ontology: Foundation of Domain Knowledge Sharing and Reusing

Domain analysis is the activity of identifying and representingthe relevant information in a domain, so that the information canbe shared and reused in similar systems. But until now, noefficient approaches are available for capturing and representingthe results of domain analysis and then for sharing and reusingthe domain knowledge. This paper proposes an ontology-orientedapproach for formalizing the domain models. The architecture forthe multiple-layer structure of the domain knowledge base is alsodiscussed. And finally, some genetic algorithm-based methods havebeen given for supporting the knowledge sharing and reusing.
