QoS Driven Service Discovery Method Based on Extended UDDI

The inclusion of QoS in Web service has been pointed out in previous work in both academia and industry. Challenge in this area addresses importance of QoS. This paper proposes a QoS driven service discovery method based on extended UDDI with the help of Semantic Web. First, a Extending UDDI Model based on QoS driven is proposed, QoS ontology is analyzed to reduce misunderstanding. Second, a matching algorithm based on fuzzy correlation calculate is proposed to filter the unqualified service to improve the discovery accuracy. Third, a discovery process based on policy is build based on Semantic Web technology. The experience results show the QoS driven Web service discovery method possesses high discovery accuracy.
