摘　　要：首先,分析相似度计算的几类方法,然后提出一个改进的基于本体的相似度计算方法。方法同时考虑了与被评估概念相关的所有上下位关系,本体中的有向边和概念属性。经实验验证,该方法简单有效。First,several approaches of concept similarity computation were analyzed,then an improved measure based on the exploitation of ontology was proposed.All subsumption relations between measured concepts,the directed edge and properties in ontology were considered together.It is proved that this approach is simple and effective.

关 键 词：本体 语义距离 相似度
