基于UDDI的语义Web服务发现的设计

The Design of Semantic Web Service Discovery Based on UDDI

基于UDDI的传统Web服务发现机制是使用语法关键字或分类目录的匹配技术,这种技术简单易懂,且易操作,但它缺乏对Web服务信息的语义支持,智能化程度不高,所以无论在精确度还是在返回率上都无法满足人们日益增长的需要。我们在原有的UDDI机制中引入OWL-S,使得请求与发布的服务能进行语义匹配,提高了这种发现机制的查全率和查准率,并给出了OWL-S/UDDI Matchmaker构架,结合OWL-S与UDDI各自的长处来实现Web服务的语义匹配功能。

Traditional Web service discovery method based on UDDI is a matching technique,using syntax or classification catalogue.This technique is simple,easy to understand and operate,but it can not capture the semantic information of web service and is lack of intelligence,so it can not meet the growing demand of people whatever in precision or return.We introduce OWL-S in original UDDI method,make the requests and the advertisements match in semantics,improve the recall and precision of the discovery method,and put forward OWL-S / UDDI Matchmaker truss,it will realize the matching function combining the advantages of UDDI and OWL-S.
