Research On Web Service Discovery Method Based On Relational Network

Web service is a cross-platform,low-coupling,programmable Web applications that can be described,published,and discovered using an extensible markup language.By using Web services technology,applications under different environment platforms can integrate with each other and then perform specific business functions without resorting to third-party software and hardware.Currently,Web services technology plays a huge role on the Internet.However,due to the isolation of services and the lack of relationships between services,Web services have not yet played their best role to facilitate user.This thesis makes in-depth research on this issue.The relationship between Web services,the network model constructed by Web services,and the service discovery methods are discussed,and a Web service discovery method based on a relational network is implemented.Experimental results show that this method works well.This thesis makes in-depth research on this issue.The relationship between Web services,the network model constructed by Web services,and the service discovery methods are discussed,and a Web service discovery method based on a relational network is implemented.Experimental results show that this method works well.This article strengthens service connections by connecting isolated services into a network of relationships.First,parameter correlations,historical correlations,and connection preferences between Web services are defined.Based on these three relationship attributes,a relational network of Web services is constructed.Then,analyze the characteristics of the relational network to verify whether the relational network conforms to the characteristics of complex networks.Based on the established relational network model,a set of linked services and a set of invoking services of known services are searched to find the services required by the user.Finally,a comparison experiment between the method used in this paper and the traditional service discovery method proves that the Web service discovery method based on relational network used in this paper is superior to the traditional Web service discovery method.
