Abstract: Aiming at difficulties in retrieving and reusing heterogeneous parametric feature models,an ontology based feature representation model was built,and a new feature ontology mapping method was proposed for representing heterogeneous product feature model information semantically.An ontology based feature model database was constructed to support the retrieval and reuse of heterogeneous parametric feature models.The ontology mapping was occurred between application feature ontology and common feature ontology,and the mapping of one to one,one to many and many to one were realized based on the feature matching with similarity evaluation.The reasoning ability of ontology and Semantic Web Rule Language (SWRL) were used for verifying the ontology mapping results to ensure the accuracy.The ontology mapping algorithm was implemented by programming.The effectiveness and feasibility of proposed method were validated by examples.

Key words: ontology modeling, ontology mapping, parametric feature model, model retrieval, design reuse
