摘要
本体概念能够有效表达Web服务的语义信息,可通过推理机实现自动语义匹配,但推理机的推理过程比较耗时,会对服务计算技术多个环节的效率产生很大影响。以本体概念间的匹配度为基础,建立公共本体概念库,可在不影响本体概念表达能力的前提下,实现语义匹配过程的分离。为适应公共本体概念库的动态特性,给出对其进行更新(添加、删除和修改)的算法。实验结果表明,该方法大幅提高了语义匹配的效率,且不会对语义匹配的性能产生影响。
The ontology concept can express the semantic information of Web services effectively, and the semantic matching based on it can be accomplished using the corresponding inference engine. But the execution of inference engine is time-consu ming, which reduces the efficiency of many stages of SOC^SOA. The public ontology concept depot based on the matching de- gree between ontology concepts was put forward {or this problem. The semantic matching was separated from other stages with- out reducing the expression capacity of ontology concept. Meanwhile, the updating （addition, deletion and modification） algo- rithms were provided for the dynamic characteristics of public ontology concept depot. The experimental results show that the method can improve the efficiency of semantic matching substantially without affecting its performances.
