摘要
针对目前本体匹配速率低的问题,基于本体技术和粗糙集理论,提出在本体匹配之前先进行3步预处理操作:规范化待匹配本体,对待匹配进行不相关属性约减以求得最小或极小属性集,属性加权统计。实验结果表明经过预处理的本体,匹配速率有了很大的提高,同时提高了本体的重用度。
At present, with the speed lower problem of ontology matching, based on the ontology technology and the rough sets theory, this paper performs 3 step pretreatment operations before the ontology matching： the standardization treatments of the ontology, the irrelevant properties reduction for obtaining the smallest or the minimum properties sets, properties weights statistics. The experimental result indicates that the matching speed has improved very much after the ontology matching pretreatment, and improves reusing the of ontology.
