Research on Web Service Discovery Model Based QoS
Jianren Wang · Information Sciences · 2007
With the large growth in number of Web services,the current Web service discovery mechanism becomes inefficient.Due to the adoption of keyword-based and simple classification,the service discovery mechanism can not meet the requirement of consumers currently,the service discoveries need to be selected and ordered based on quality of service.Based on research,the paper analyzes the three factors influencing the service discovery,namely as static factors,dynamic factors,statistical factors and adopts the syntax and semantics of the Constraint-based Requirement Specification Language to describe the quality constraint firstly,And then describe the quality of service by extensions to WSDL,at last a web service discovery model is proposed,which can be implement through the direct extension to the existing UDDI services.
