摘要
本文提出一种基于OWL-S的语义web服务匹配系统的机制,将语义元素引入UDDI系统中,从而在UD-DI中保存语义信息.系统通过语义服务匹配算法提高web服务匹配的准确度和召回率,并通过数据映射机制保证模型对于当前的服务发现标准UDDI基础架构的兼容以及UDDI标准操作接口的透明性.系统使用本体概念的索引机制提高服务发现的效率.而且,系统在建立和维护索引的过程、或服务的匹配过程中使用近似概念搜寻算法进一步提高本体概念搜寻和服务匹配的效率.
The paper proposes an OWL-S based semantic web service matchmaking system mechanism,which imports semantic elements into UDDI,and preserves semantic information in UDDI storage.The system employs a semantic service matchmaking algorithm to improve precision and recall of service matching,and uses a data mapping mechanism to ensure the compatibility with present web service discovery standards,UDDI,and the transparency of UDDI APIs.The paper designs an ontology concept indexing mechanism for the system to improve the efficiency of service discovery.Moreover,in the processes of building and maintaining the indices,or alternatively,matching services,the system uses a similar concept searching algorithm to further enhance the efficiency of ontology concept searching and service matchmaking.
