Design And Implementaion Of Organization And Composite Application Of Semantic Web Service

With the development of Web service technology, more and more service providers participate in it, expanding the number of services, and more services are applied in websites and softwares. More applications bring more demand, in which simple ones can be completed by a single service, complicated ones, however, require multiple services together to complete the mission. Current methods for combining multiple services mostly contain the following disadvantages:First, users are limited to people with expertise in the industry, the general public can not use them; Second, semantic information is underutilized. Much attention has been put into the combination process, while the importance of semantic information is ignored in the service selection, which leads to the lack of accuracy and speed; Third, complex services are not immediately executed and users cannot see the results directly. This paper presents a conceptual diagram of semantic web services modeling method, and an approach from the general public’s input to the feedback of composite services’execution.To start with the field of web service organization and combination, we analyzed industry background and existing research status, introduced related technologies involved in this study, including service clustering、 business processes and natural language processing. Requirements of the system and different parts are described, with the application scenarios、 functional and performance requirements、the system architecture layout and functional requirements of each section. We also illustrated the organization of semantic concept diagram and the method of generating composite service, proved the correctness and usability through experimental verification. In the implementation of the system, we selected the field of tourism as an entry point, and constructed the architecture and every module of tourism service system. Every module and the whole part are operating normally in testing, which archieved the expected results. Finally, the paper summarizes the whole research and lists the aspects that can be studied with further research work.
