基于OWL的本体映射中概念相似度计算方法的研究

随着网络上的本体越来越多，为了实现不同本体间的知识重用和共享，需要在本体间建立映射。而建立映射的关键在于找到概念相同或相近的实体对。借鉴计算语言学中的语义距离思想，提出了基于OWL构词所描述的本体概念相似度计算方法，该方法充分考虑了概念本身、概念属性、概念所处的层次结构和概念的OWL语义四个方面的语义相似度。

Research on the Method to Calculate the Semantic Similarity of Ontology Mapping Based,on OWL

With the increasing number of ontologies,in order to achieve knowledge reuse and sharing among different ontologies,it is necessary that mapping be established among ontologies.Furthermore,the key of establishing mapping lies in finding entity pairs that are the same or similar in concept.A method to calculate the semantic similarity of the ontology concepts described by OWL constructs was proposed on the basis of the semantic distance theory in the linguistic field.This method fully consider the semantic similarity of concept itself and concept's attribute and concept's hierarchy and concept's OWL definition.
