STEP AP203 is a standard for exchange 3D CAD models. The second edition of AP203 is support to express the constructive solid geometry with construction history. However EXPRESS language is not support to express semantic relations. So it is hard to trace the design history. In this research, we suggest an expression of OWL(Web Ontology Language) based CAD models to trace the design history.

Design data, information, and knowledge have complex associations with each other. Systems related with the management of the data, information, and knowledge are various, and the representations are numerous. Therefore it is difficult to construct a knowledge based design system with a full association knowledge for supporting the design tasks. In this research, OWL based ontology model for an excavator design is developed for the representation of the relationships. Also an ontology model is used to develop the knowledge based excavator design system.

It is continued to study on a knowledge based system for supporting a design of an excavator front group. However, an analysis of a knowledge type and structure of the excavator design was lack. The architecture of the system was not designed with a well-organized knowledge. In this research, an analysis of the knowledge type and structure of the excavator design is performed. Based on the analysis, a knowledge model and a knowledge based system for the excavator design is proposed and implemented.

A meeting is an assembly or gathering at a prearranged time, usually to discuss specific topics and to exchange information about the specific topics. It is essential for an efficient group meeting to provide an organized representation of the meeting. A representation of ontology for the meeting will be an answer for the organized representation to support the meeting efficiently. Moreover the ontology can provide an inference scheme from the meeting concepts such as domains, sub-domains, classes, properties, and relationship of meetings. In this paper the strategy for the domain decomposition, the definition of features, and the ways in which features are shared by various operations and structure changes, are discussed. We conclude with a discussion of some of the issues raised by the project and the steps underway to address them.
