基于OWL-S的Web服务匹配的研究

Study of Web Services Matching Based on OWI-S

服务匹配是Web服务发现中一个很重要的部分。针对目前服务发现方法的描述缺少灵活性和表示性的不足,文章提出了一种基于OWL-S的Web服务匹配算法,其核心思想是用OWL-S进行服务描述并将其发布后,通过对服务描述中的输入输出和用户需求中功能的测度来判断服务与用户需求的匹配程度,将UDDI和功能匹配结合起来,使得用户能够更好地进行服务查询。

Web service matchmaking is an important aspect of the web service discovery. The main shortcoming of the current approaches of publishing and discovering web service in the internet is that they are lacking of much flexibility and expressiveness in the service descriptions. So An arithmetic for web service matchmaking based on OWL-S, in which web services are described by OWL-S and be advertised, is proposed in this paper. The matchmaking degree is measured between input/outputs of web service description and capability of users＇ requirements. We can combine the UDDI and the capability-based matching in order to get better service select for users.
