| With the development of Internet, network examination has got more and more extensive application. Network testing system has been a big concern of both national and international education reform. Because of the current state of the national education, it is more urgency and importance of the wider application of network examination system.Furthermore, in the main construction of existing examination system are C/S constructions, causing that the client end is too huge. And need keep the rather long communication between the client end and the server end. To overcome these problems, the Agent technology of AI field is adopted in the examination system. The Agent technology provides the new development space for network examination system.The Agent technology offers a new method for the analysis and design of open system. An analysis and study of network testing system has been made. And import the concept of Agent in order to overcome the localization of former system. Design and study for network examination system by making use of Prometheus which is an Agent-Oriented Software Engineering. Then establish the exploitation project. Build the network examination system model under the mode of Agent by using of PDT and three design phrase of Prometheus-system specification,architectural design and detailed design.At last we discuss emphases and difficulty of above-all facial expression recognition methods, and put forward the future work development and direction. |
