A Uniform Product Knowledge Representation Semantic Model

Aimed at the uniform knowledge representation including STEP and SGML in the virtual organization, XOEM+OWL is put forward which is the semantic model faced on the uniform product knowledge representation on the multi heterogeneous product information. And then the correspondent mapping between STEP schema graph and OWL schema graph are build as Cos(sc,oc),so we can get the semantic pattern matching degree for the semantic representation on the product information. At last the example is presented
