基于本体的领域知识重用方法研究*

由于已有知识表示和本体知识表示并不在同一逻辑体系基础上，从知识表示层面提出了一种基于知识等价映射的知识重用方法解决对已有异构知识的重用问题。通过语义等价提取、在本体指导下的一致性处理以及语义映射解决了本体构建过程中对已有知识的自动重用问题。实验表明，该方法易于实现且具有较高的精确性、可行性和有效性。

Study on domain knowledge reusing methods based on ontology

This paper proposed an issue on existing heterogeneous knowledge reuse based on the solution of knowledge reuse of knowledge equivalent mapping from knowledge representation level, since existing knowledge representation and ontology knowledge representation weren't on the same base of logic system. This approach using semantic equivalent extraction and the consistency treatment under the guidance of ontology, and semantic mapping solved auto-reuse of existing knowledge in the course of ontology construction. The experimental results show that the approach is realized easily and has a relatively high accuracy, feasibility and validity.
