Converged Service Based On SOA4All Architecture In Semantic Web Of Things

IoT (Internet of Things), which links the physical world objects by radio frequency identification and other information sensing device with the Internet, so as to intelligently identify and manage these objects. It is a kind of Internet application that can share the information of things all over the world. In the Internet, the information at different locations can be uploaded to the Internet. However, Internet of Things itself exists two internal contradictions:diversity in the form of information representation and the information user lack of understanding ability. Therefore, it is required to explicitly define the semantics of things. The main strutter of the semantic web-ontology, which can be used to describe information about the objects on the level of semantic and knowledge, in order to be understood by the machine, so as to make the function of Internet of Things has a qualitative improvement, the Internet of Things should actually be SWoT (Semantic Web of Things).It is a major problem that how to accurately find the service needed by users in SWoT. In order to solve the above problems, this thesis proposes a method of service converged based on SOA4All architecture in Semantic Web of Things. Firstly, this paper introduces the SOA4All architecture, which is an extension of the traditional SOA architecture. SOA4All architecture is mainly used for processing services dynamic interaction and collaborative awareness in Semantic Web. The service discovery in the traditional SOA architecture, is based on the similarity of key words or structure, which does not take into account the comparison of semantic similarity. The service discovery in SOA4All architecture increases the matching of semantic information by creating semantic feature index tree for service. Then, services exchange information through the Orchestration or Choreography. Finally, the service converged template make the atom service which has a single function converged for more complex structure of complex services, which is to meet the users need.According to the above methods, this thesis designs and implements service converged system based on SOA4All architecture in Semantic Web of Things SABSCS. Finally, a test set is used to the experimental verification of the system. The experimental results show that the design prototype system in this thesis is capable of effective service converged, and the proposed method in this thesis provides a novel approach to service converged and find the service which users need.
