Semantic Web Service Automatic Composition Based on Service Parameter Relationship Graph

Due to the features of service scattered in service- oriented computing (SoC) environment, such as uncertain, dynamics, and the complexity and levity of business process, it has become more and more difficult to meet the user´s requirement to compose automatically services at runtime. This paper proposed a new architecture of service composition based on cloud computing technology to achieve the mapping between the cloud service and abstract service, and the service parameter relationship graph based on semantic was put forward to achieve automatic composition. The experiment showed that our approach has better success rate and efficiency of service composition than the existing method to achieve the automatic real-time service composition at runtime.
