For constructing semantically rich service descriptions in Grid services, emerging ontologies are being used. To generate ontologies, an issue named "ontology bottleneck", the lack of efficient ways to build ontologies, has been coming up. Therefore, it is an urgent task to improve the methodology for rapid development of more detailed and specialized domain ontologies. However, it has been a hard task because domain concepts have highly-specialized semantics and the number of concepts is fairly large. In order to reduce the cost, DODDLE II (a domain ontology rapid development environment II) has been developed in our research group. In this paper, we confirm the significance of DODDLE II. In addition, we introduce our plan for further extension for the Semantic Web as a future work.
