一种新的基于相似度计算的本体映射算法*

领域本体在知识的共享和重用方面起着重要的作用。本体映射是解决本体异构，在不同本体间建立语义关联的一种有效的方法。针对不同本体间的本体概念映射提出了一种新的概念相似度的综合计算方法，从本体概念名称、属性、结构和实例四个方面讨论本体概念的相似度，同时提出在涉及概念名称和属性名称时，使用其同义词扩展集参加计算，计算综合相似度时，分别用手工和自动的方法赋予权值。实验证明改进的算法提高了本体概念映射的查全率。

New similarity-based approach for ontology mapping

Domain ontology plays a key role in knowledge share and reuse. Ontology mapping is an effective method of solving the heterogeneity of ontology and setting up semantic relevance. Aiming at ontology mapping between different ontology, this paper proposed a new synthesized algorithm of concept similarity. The presented algorithm involved concept name, attribute, structure and instance levels, at the meantime used the extended synonym set in computing concept similarity-based concept name and attribute name. The experiment shows that the improved algorithm outperforms in precision of ontology concept mapping.
