摘　　要：为了解决语义Web服务匹配方法主要针对服务输入/输出匹配而导致功能匹配结果较为片面的问题,提出了一种基于描述逻辑的语义Web服务前提/效果匹配方法.利用描述逻辑知识库一致性检查推理,判断服务请求与广告的前提/效果之间逻辑蕴含关系,建立类匹配度概念,并由此度量和比较前提/效果匹配结果的优劣,从而对匹配结果进行有意义的排序及分类.实验结果表明,所提方法在查准率与现有方法相当的情况下,具有更高的查全率,特别是将输入/输出与前提/效果匹配一并考虑的情况下,能够更好地区分匹配结果.Since the results of the existing matchmaking methods for semantic web service are more one-sided by only focusing on the matchmaking of inputs/outputs descriptions, a description logic based semantic Web service preconditions/effects matchmaking method is proposed. The knowledge base consistency checking function of description logic reasoning is used to determine the logical implication between preconditions/effects of service requests and advertising. A compatible matching degree is proposed to measure and to compare the pros and cons of the results of preconditions/effects matchmaking. Experimental results show that the proposed method has a higher recall rate with a considerable precision rate. In particular, better matching results are ob- tained when both the inputs/outputs matchmaking and the preconditions/effects matchmaking are combined.
