本体映射中一种改进的概念相似度计算方法

本体映射是实现不同本体之间共享和交流的基础性工作。目前本体映射方法研究的重点主要集中在以自动化或半自动化方式实现映射和提高概念相似度计算的精度。本体映射的关键是不同本体概念间相似度的计算，单一的概念相似度计算方法往往不利于提高相似度的精度。针对以上不足提出了一种改进的概念相似度计算方法，并对其进行详细的描述，其中属性语义相似度计算方法改进了现有的基于属性计算语义相似度的方法，综合了数据类型属性和对象类型属性的语义相似度。经实例验证该方法有效且具有较高的精度。

Improved concept similarity computing approach in Ontology mapping

Ontology mapping is a preliminary work to realize the communication between different Ontologies. The current studies on ontology mapping approaches mainly focus on fulfilling mapping process automatically or semi-automatically and enhancing the precision of concept similarity. The key of ontology mapping is to compute the concept similarity, single concept similarity computing approach is not in favor of improving precision of the result. In view of the above shortcomings, an improved concept similarity computing approach was proposed and described in detail. The property semantic similarity of this approach improved the existing approaches to the similarities of both data type property and object type property. It is proved that this approach is effective and has high precision.
