针对目前本体映射过程中相似度计算存在的问题,提出了一种综合的相似度计算方法。首先判断不同本体之间是否存在相关性,若相关,则充分考虑各种相关因素,从语义和概念两个层面来进行比较;然后给出本体的综合相似度计算方法;最后采用两组测试数据对该方法进行实验,并与GLUE系统的概率统计方法进行了实验对比。实验结果表明,该方法能够有效确保相似度计算的准确性。
Aimmed at the current problems, this paper put forward a eompositive approach of similarity computation. It judged the relativity among different domain ontologies first. And then in this subsumption,based on semantic level and concept level, proposed a comprehensive similarity measuring method, after took a full consideration about relative factors, Lastly this app- roach tested with two datasets and compared it with probability statistical method of GLUE system. Experiment results show that this approach can significantly improve the precision.
