摘　　要：针对异构参数化特征模型难以检索重用的问题,建立了基于本体的特征表示模式,提出一种新的特征本体映射方法,将产品模型特征信息进行统一的语义描述,建立基于本体的特征模型库以有效地支持异构参数化特征模型的检索和重用。本体映射在系统特征本体和公共特征本体之间进行,基于相似性评价指标进行的特征概念匹配能够实现一对一、一对多和多对一的映射,并利用本体的推理能力和语义网规则描述语言对匹配结果进行检查,以保证本体映射的准确性。编程实现了本体映射算法,通过实例检验了方法的可行性和有效性。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.
