Research On Semantic-based Interaction Adaptation Model Of Service Behavior

With the continuous development of the research technology and the continuous expansion of the research area which is related to the Web service, the idea and technology based on semantic technology is introduced into each segment of the service computation to solve the critical and difficult problem in the area of realizing the intelligent and accurate service computation. How to attach semantic information to the model of service behavior which expresses interactive behavior and dynamic adaptation, how to realize semantic identification, semantic judgment and semantic adaptation in the process of behavioral manipulation, how to promote the intelligence of Web service behavior, all of these problems has become an important factor in the field of service computing research, especially in the process of development from simple interface model to complex behavior mode.The research background and significance of the service behavior interaction and adaptation model based on semantic information are reviewed in this paper.The domestic and foreign research foundation about the formalized representation method of the model of Web service interaction, and the status of service adaptation method are also summarized. C_net,which is an advanced Petri net and has strong capability of description,is proposed to extend, in order to formalize expression of service interaction model based on semantic information and to explain the semantic information and the service behavior rules which need to be attached within the service behavior. The mismatch detection model in the process of the interaction between service behaviors based on semantic is set up and the detection algorithm of semantic mismatch is put forward. With the consideration of the change of semantic information which caused by service behavior in dynamic interaction with different users, at the same time, the semantic mismatch is detected and classified based on the change of semantic information. According to different types of semantic adaptation model caused by the mismatch generated in the process of dynamic interaction between service behaviors, the generation algorithm of semantic adaptation model is put forward, making the service behavior come true normally and the semantic information is accordant. Finally, Web audio downloaded system, which is based on semantic, is modeled and analyzed by using C_net. As a result, it can attach the corresponding semantic information to each activity and behavior rule of the audio download platform and users’ request service, generate corresponding semantic adapter based on the effect which caused by semantic constraint and semantic mismatch and implement the maximized interaction among the Web download audio platform and users in the level of service semantic operation.The main work of the paper is that the dynamic interaction and the adaptation model of service behavior is introduced based on semantic by using C_net. At the same time, the constraints based on the dynamic semantic information are introduced for the service interactive behavior model and adaptive technology while the semantic mismatch and corresponding adaptation strategy caused by service interactive and dynamic execution are also discussed. Profound theory is provided to improve the accuracy and execution of the service behavior interaction.
