Construction of a Personalized Technical Chinese Learning SystemUsing Personalized Role-Playing Method

本研究致力于结合角色扮演的方法开发个性化的技术汉语学习系统。研究结果如下：〓我们将网络集体智能的概念应用到本研究中，提出了一种自动生成试题的方法。基于此，我们设计了一种个性化课程来评估学习者的能力。〓我们研究了允许学习者与虚拟对话者进行互动对话的环境构建，并提出了一种在对话中处理未知词的方法。〓我们提出了一种通过分析学习者的话语过程来估计学习者感觉和意图变化的方法，并对该方法的精度进行了考察。这使得更恰当地描述学习者的疲劳程度和感觉成为可能。

This study focused on the development of a personalized technical Chinese learning system by incorporating the role-playing method. We obtained the following results:〓 We applied the concept of Web collective intelligence in this study and presented a method of building test problems automatically. Based on this, we devised a method of personalizing the course to assess a learner’s abilities.〓 We investigated the environment construction to allow a learner makes interactive conversation with a virtual interlocutor, and presented a method of handling unknown words in conversation.〓 We presented a method to estimate the change of a learner’s feeling and his intention by analyzing the utterance process of the learner, and investigated the precision of the method. This makes it possible to more suitably describe the learner’s degree of fatigue and his feeling.
