一种基于词语相似度计算的本体映射方法

An Ontology Mapping Method Based on Lexical Similarity Calculation

本体映射是解决本体异构的有效手段。针对本体映射中概念相似度计算存在的不足,提出一种改进方法。将WordNet的同义词、近义词检索和编辑距离算法引入术语中心词之间的相似度判断过程,并借助新的自动权重分配方法对术语中心词和术语修饰词相似度进行集成。通过与同类典型本体映射方法对比实验证明,该方法具有良好的效果。

Ontology mapping is one of the solutions to Ontology heterogeneity problem. To solve problems that still exist in current concept similarity calculation algorithms, the paper puts forward an improved method, which introduces the syn- onym/homonym search and edit distance algorithm into the process of term head words similarity calculation. The new au- tomatic weight assign method is also used to integrate the similarity values of head words and modify words. Compared to the other classic Ontology mapping method of the same type, it is proved the improved method has better effects.
