摘要
为了解决Web服务发现中存在的本体异构问题,研究了基于本体概念及属性的简单本体映射。在已有本体映射方法的基础上,通过引入广义信息的概念,提出了一种针对关系映射的改进方法,将简单映射扩展成复杂映射,并使用广义信息中的广义熵概念优化了相似度计算的方法,剔除了其中不相关的计算。实验结果表明,该方法在不影响查全率和查准率的前提下大幅度地提高了时间效率。
To solve the problem of ontology heterogeneity,the ontology mapping based on concept and property of ontology are rese-arched.On the basis of the existing methods of ontology mapping,an improved method in accordance with relation mapping is introduced through importing the concept of generalized information to spread the simple mapping to complicated mapping,and method of similarity computation are optimalized using the generalized entropy in generalized information,then some unallied computations are reduced.Finally the efficiency is enhanced based on the premise that the recall and precision ratio are not changed by the experiment.
