Abstract
Web service matchmaking is an important aspect of the Web service discovery, and some efficient matching algorithms of matchmaking services are required in a dynamic biomedical environment especially. The main shortcoming of the current approaches of publishing and discovering Web service in biomedical informatics, which are basing on WSDL and UDDI, is that lacking of much flexibility and expressiveness in the service descriptions. Hence the algorithm for Web service matchmaking based on semantic is proposed in this paper, in which Web services are described and advertised by OWL-S, and experimental results indicates the matchmaking degree is improved between different parameters of Web service description and capability of users’ requirements, which can provide better service choice for the users.
