Cloud Studio:a User Model Based Service Composition Platform

Service oriented technique is now popular and service integration is more mature. However it is difficult for ordinary user to execute web service or compose web services directly. The process of service composition is not customizable. Besides, users are easy to get overwhelming.To match the web service in technical scope to the business semantic scope, and propose a method to convert from business model to executable process model, the author has done a research on service oriented applications and proposes this Cloud Studio which supports service modeling and user model based service composition and searching. User preference model consists of taxonomy and properties features and represented by those semantic concepts. An algorithm is proposed to measure the correlation of user and resources. In terms of the service composition and searching, the scenario users faced is relatively static. By abstraction of actions and parameters of web services of a specific field, heterogeneous web services can map to these interfaces. With the domain related constraint posted by user and preference vector in user model, the process of composition and searching service among multiple service vendors is realized.The composition and searching function by Cloud Studio can satisfy the customization of demands, improving quality and degree of satisfactory of service, which realizes the revolution of integration and sharing of resources, as well as intensives and systematization of management.
