【摘要】 随着信息技术的飞速发展,在E-Learning的研究领域中,情形分析、情感激励和导航已逐渐成为该领域内的一个活跃的研究方向。它的目的是要通过分析学习者的学习情形,进一步分析学习者的情绪,以提供相应的情感激励和有效的学习导航,以激发学习者的学习兴趣,提高学习效率。本文首先介绍了课题的研究背景和E-Learning环境中情形分析、情感分析和导航的研究现状等,总结了束缚E-Learning中情形分析、情感分析和导航发展的瓶颈问题。同时引入本体论概念,简介了本体在E-Learning中的应用。在此基础上,本文提出了E-Learning环境中基于本体的情形分析、情感激励和导航,具体内容如下:1)提出了E-Learning环境中的情形本体模型。在该模型中,通过对E-Learning环境中的学习情形信息进行分类总结,利用本体论进行本体建模,使得各种情形信息能够有机的结合在一起,清晰地展现了概念、逻辑之间的内部联系和相互之间的依赖关系。另外,在情形本体模型的基础上,提出了个性化情形信息获取的方法,通过对个性化情形信息的及时更新,可以获取更为及时准确的情形信息。2)提出了E-Learning环境中的本体规则推理情形分析处理模型。在该模型中,对用户的各类学习情形信息进行了分析和推理,以及时准确的判定出学习者的学习情形状态。在此基础上,又提出了本体规则推理情绪分析处理模型和本体规则推理实时性导航处理模型。在情形分析的基础上,分析不同情形状态下学习者的情绪,并针对不同情绪给出相应的情感激励。并根据学习者不同的情形、情绪,提供针对个人的实时性导航。3)在情形本体模型和本体规则推理情形处理模型、本体规则推理情绪分析处理模型以及本体规则推理实时性导航处理模型基础上,利用相关的技术和工具,实现了一个基于本体的E—Learning环境中的情形分析、情感激励和导航系统,从实验角度验证了上述方法的合理性、有效性。更多还原

【Abstract】 With the rapid development of the information technology, situation analysis, emotion encouragement and guide become a very active research direction in E-Learning field. It aims to analyze learner’s emotion by analyzing their studying situation and provide emotion encouragement and effective study guide. It can stimulate learner’s studying interest and raise learner’s study efficiency.First, we introduce the research background of the subject and the state of the art of this research, such as situation analysis, emotion analysis and learning guide in E-Learning environment. Then we give the concept of ontology and introduce the application in E-Learning field. On base of these, the methods of ontology based situation analysis, emotion encouragement and guide in E-Learning environment are presented. Concrete contents are as following:1) A situation ontology model in the E-Learning environment is presented. In this model, all kindes of situation information are combined organicly by classifying the learning situation information and using the ontology. The concepts and the relationship of the learning information are emerged clearly and accurately. Besides, a method of extracting personalized situation information is presented on base of the situation ontology model. By updating the personalized situation information, the learning situation information can be got timely and accurately.2) A situation processing model based on ontology rule reasoning in the E-Learning environment is presented. In the model, the learner’s learning situation information is analyzed and reasoned, and the learner’s learning situation can be concluded timely and accurately. Furthermore, the emotion analysis model and the learning guide model based on the ontology rule reasoning are also presented. The learner’s emotion is analyzed on the base of the learning situation. And the real-time guide is provided according to the learning situation and emotion.3) Basing on the situation ontology model, situation processing model based on the ontology rule reasoning, emotion analysis model and learning guide model, an ontology-based E-Learning system with situation analysis, emotion encouragement and learning guide is developed by using some techniques and tools. It can be used to prove the effectiveness of above approaches.更多还原
