Ontologies and Object Models in Object Oriented Software Engineering

This paper is to clarify ontologies in knowledge base compare with object models in object oriented software engineering. Ontology itself has the concept which is the foundation of knowledge base; on the other hand the object model is the center of object oriented software engineering. Because ontologies are closely related to modern object-oriented software design, it is natural to adapt existing object-oriented software development methodologies for the task of ontology development. Selected approaches originate from research in artificial intelligence; knowledge representation and object modeling are presented in this paper. Some issues mentioned in this paper are related with their connection; some are addressed directly into the similarities or differences point of view of both.
