【摘要】 随着Internet的发展,网络考试系统得到了越来越广泛的应用。网络考试系统的发展一直是近些年来国内外教育改革的一个方面。由于近些年人们对教育的需求不断的增加,以及我国由应试教育转向素质教育的教育教学改革的现状,网络考试系统的研究与推广显得尤为的重要。现有的网络考试系统基本上是C/S结构的,客户端过于庞大,而且需要客户端和服务器端保持长时间的连通,为了克服以上的缺点,我们将人工智能领域中的多Agent技术应用于网络考试系统中,从而为网络考试系统的研究提供了新的发展空间。Agent技术为分布式开放系统的分析、设计和实现提供了一种新方法。本文在对网络考试系统分析和研究的基础上,针对原有考试系统的局限性,引入了Agent概念,利用面向Agent的软件开发方法之一—Prometheus方法对网络考试系统进行了研究和设计,确立了开发方案。根据Prometheus方法中系统说明,结构设计,细节设计这三个阶段的研究和开发,利用PDT作为建模工具,建立了一个Agent模式下的网络考试系统的新模型。最后,对本文工作进行了总结,提出了进一步的工作方向和思路。更多还原

【Abstract】 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.更多还原
