Research Of Domain-Oriented Dynamic Generation Of Web Service Process

With the development of Internet, the network has depth influences in all aspects of people's lives and is having great changes on people's lives. There is a growing requirement for people to access to a variety of information from the network to help to complete their missions. The emergence of Web Services provides the abilities to communicate between each other automatically, and Web Services are rapidly growing Internet-based standard framework for cross-organizational and distributed applications. Network can provide users with more powerful functions by coordinating, organizing, and calling Web services. However, in a lot of circumstances, in order to meet user complex and individualized needs, and make Web Services work best, it is required to organize Web Services into flows. Through collaborative, highly interactive workflow management system organizing Web services to complete our missions becomes a viable solution, but the traditional workflow system is for internal enterprises in general, so the Internet environment organization and management of Web services brought new challenges to the traditional flow model. How to integrate existing Web services more rationally to meet user's need becomes a hot spot in the field of computer research, and it also made many research results. However, with the scale of the expansion of network applications, Web services exist in similar functional but different properties, while users expect personalized service and so on, the complex demands make us build more intelligent flow model for each user to provide high quality services.This paper presents a method of Web Services auto-generated flow based on domain, and the method can satisfy user personalized information. The main contributions are as follows:1. This paper presents a domain-oriented service registry and discovery model which supports for the flow of Web Service automatically generation strongly. Domain-oriented Web Services Registry model is set up on the standard of Domain Service Ontology, builds up the mapping relationship between the service description document element and the domain ontology, and then generates the standardization information for services, and last stores services to the semantic service database. Based on this model, a corresponding domain-oriented service discovery method is proposed. Under this approach, you can quickly find the Web Service to meet user demands.2. A new method of business processes personalized generation from user needs is proposed. This method is different from pre-established tourist flow, but automatically generates a new flow of tourism to meet the requirements of user personalization. The flow generation method is to manage and maintain user's personalized information by user profile, and to construct the semantic requirement description using domain ontology, then to call the decomposition method, and last get the services sequence. Service list is ranked by the evaluation of the sequence of priorities. The service sequence with the value of high-priority will be called firstly. When the flow executes, if the service called is unavailable or not satisfied, we can use the replaced service or flow to replace it.Through the verification of Web service process generation examples and comparison with the previous analysis, further illustrate the domain-oriented Web service process generation method is effective and feasible.
