Research on Domain Requirement Analysis Method Used Ontology

The domain requirement analysis not only is the important content to put domain engineering into practice, but also is the guarantee to realize domain specific software reuse. However, there is the "communication gap" among the domain requirement analysis because of the difference comprehension to domain knowledge. To resolve the problem, a method of domain requirement analysis based on the Ontology is studied, which utilizes the advantages of the Ontology in expressing domain knowledge and provides a well defined and unambiguous requirement definition to overcome "the communication gaps" among domain analysts. Finally, an instance of building domain Ontology by UML is presented to depict the process of domain requirement analysis Ontology-based method.
