基于领域本体映射的综合相似度计算方法

Integrated Similarity Calculation Method Based on Domain Ontology Mapping

领域本体为知识的共享和重用提供重大作用。本体映射是在异构本体间建立语义映射关系,解决本体异构的重要途径。针对目前本体映射中相似度计算存在的不足,提出一种综合的相似度计算方法,即先依据知网知识词典并考虑未登录词分词后词性的作用,计算出本体元素的概念相似度;再分析本体的层次关系计算其结构相似度;通过加权综合得到本体的综合相似度;最后构建两个异构航运本体,设计实验来验证改进后算法的正确性和有效性,实验表明所提出的方法具有较高准确率。

Domain ontology plays a vital role in the sharing and reuse of knowledge. Ontology mapping is an effective way to solve semantic mapping between heterogeneous ontologies. Aiming at the disadvantages of the similarity calculation in ontology mapping, proposes a comprehen- sive similarity calculation method, which is based on the knowledge dictionary and considering the role of the word after the word, and calculates the similarity of the ontology element. Finally, designs two heterogeneous shipping ontologies and design experiments to verify the correctness and validity of the improved algorithm. Experiments show that the proposed method has higher accuracy.
