Research And Application On Interface Agent Model Based On DFL

With the maturity and development of the agent technology , agent technology is widely used in intelligent interface. An interface agent, also called software agent, cooperates with the user to accomplish its task and functions as the user's personal assistant. And now, the key problem in the interface agent research fields is user modeling and user intent induce ,that is knowledge representation machine learning methods and inference technology. Dynamics and uncertainty are available in the interface agent research field based on the research content of the human-machine interaction, such as dynamic fuzzy interaction concepts , dynamic fuzzy interaction relationships , dynamic fuzzy temporal interaction and dynamic and fuzzy user intent. Methods which have been presented can not resolve the dynamic fuzzy problems in the interaction adequately, such as Bayesian Network and Neutral Network. With this practical demand, this paper research interface agent based on Dynamic Fuzzy Logic theory. As the research information showing, Dynamic Fuzzy Logic theory is one of the most effective tools to describe dynamic fuzzy problems. So we utilize Dynamic Fuzzy Logic to build an interface agent model, which has academic and practical significance and is the innovation of this paper. We proposed a interface agent model based on DFL theory, which can predict user intent by incorporating the ability to explicitly model user's goals, the uncertainty in the users' intent inpursuing these goals, and the dynamic of users' behavior. And our work include five respects as follows:(1) gave a interface agent user model based on DFL(2) gave a user modeling method based on DFL(3) gave a user intention reasoning method based on DFL(4) gave a interface agent architecture based on DFL(5) Apply the interface agent model to the information search engine Through the work above, we can describe the dynamics anduncertainty in the interface agent and propose the theory base that canhelp other researcher build more personality and intelligent user interface.And the work can make up for the inadequate of the exist theory and helpfind a new way to research interface agent.
