QoS-Supported and Adaptive Model for Web Service Discovery
Zeng Qing-yin · Jisuanji gongcheng · 2008
Quality of Service(QoS) is a key issue in web service discovery.This paper proposes a QoS-supported and adaptive model for Web service discovery,which satisfies users' functional requirements of Web service,and selects and ranks Web services based on the non-functional criterions.A Web service selecting and ranking algorithm is presented,which estimates Web service's non-functional criterions dynamically based on the criterions registered by Web service,information fed back by users and service's realtime data.And the most appropriate Web service is returned to the user.Experimental results prove that the model improves the availability of the whole system.
