Service Community-Based Service Heterogeneous Processing Method Research

Web services are the kind of services that with high degree of interoperability, loose coupling and cross-platform features. With the development of Web services technology,more and more Web service providers share their services whice are simple and flexible by Internet.In real applications,in order to meet the purpose of the complex needs of the service requestor, people often combine some single Web services,through the organization and implementation of different functions of Web services,they can finish more complex systems work and provide more extensive function,in this way people can better meet the needs of the service requester. Some times, current Web service in combination of services may be unavailable due to the complexity of the network and the service individual factors.Howerer, there may exist interface heterogeneous between different Web services, direct substitution between the two services is not allowed.Therefore, the message exchange between two Web services which exist interface heterogeneous is one of the hot issues in recent researches.For the problem of message transformation between two services which exist interface heterogeneous, this thesis puts forwards Web service proxy-based heterogeneous resolution strategy,in this strategy this thesis achieve the conversion of heterogeneous information through service agents.This mechanism is divided into three parts,including community services agency supporting services community research, service heterogeneous information metrics and heterogeneous information processing method.Firstly, this thesis puts forward a service agent mechanism. This mechanism try to unified the service calling interface through the service proxy, and implement service agent through service community-based general operation. Secondly, in order to describe the heterogeneous information between two services, this thesis puts for ward a service measure method,with this method,the community could value the heterogeneous information that between the service interface which registrated by service providers and the the general operation in community, including the detection of the interface contains relationshipi and the calculation. of interface heterogeneous degree.Next,this thesis presents the service heterogeneous information processing process,converse the interface parameter information from the source form to the purpose form by the combination of the service mapping informationand and the heterogeneous processing services.Finally, this thesis reveal the design and implementation of service agency supporting community. These experiments verify the effectiveness and practicality of the reliability-driven service selection approach.
