摘要：

针对本体模型的结构特点，从模型概念间的宽度、深度、密度等方面分析本体概念相似度的计算，将其合并为结构因素。结合语义重合度、语义距离等影响相似度的因素综合考虑，提出一种基于本体结构的计算概念间语义相似度的算法。通过建立本体模型并进行实验分析，总结出本体结构方面各因素对本题概念语义相似度的影响。

Abstract:

According to the structural characteristics of ontology model, this paper analyzes the concept similarity computation based on the width, depth and density among the concepts of ontology model. It considers these aspects as structural fact and combines other facts such as semantic contact ratio and semantic distance. An algorithm of semantic similarity computation based on ontology structure is proposed. Through constructing ontology model and analyzing experiment, it summarizes the effects to the ontology concepts semantic similarity of different facts about ontology structure.

Key words: ontology, concept, semantic similarity, ontology structure
