Abstract
It is one of the most efficient ways to develop and extend ontology database by acquiring field concepts and knowledge contained in the existing and available data resource. A semi-automatic reverse engineering approach is proposed to construct part resource ontology based on heterogeneous CAD(Computer-Aided Design) model documents. Due to offer reference to automatically acquire part resource library details, the information exchange mechanism is described between part resource library and CAD system, and then the part resource ontology extraction frame and semantic model construction process are illustrated based on reverse engineering. Additionally, the part resource ontology storage model based on relational database (RDB) is proposed to fulfill efficient storage and management to OWL (Web Ontology Language) ontology. Finally, the feasibility of this approach is verified by an example for part resource ontology construction and instance extension.
