【Abstract】 It’s not easy for traditional standards such as STEP to describe product information in a semantic way, andthese limitations result in difficulties in knowledge-based product information integration. In addition, contemporary computing environment needs a Web-based language to describe product information, while STEP standard and its EXPRESS language have no such features however. The development of Semantic Web is making itself be an important method to facilitate the knowledge-based information integration. This paper presents a new semantic Web language, DAML+OIL, and tries to use it to describe product information. It is proved that using DAML+OIL to describe product information is quite a feasible way.更多还原
