基于情感学习本体的教学反馈策略生成算法的研究

研究如何采用本体建模的方法解决智能教学系统中的情感理解与情感反馈的问题。构建了一个情感学习本体用于描述在学习过程中出现的与情感相关的概念及概念之间的关系,设计了基于该本体的教学反馈策略的生成算法,可以在不需要和学生进行问答交互的情况下获得学生学习过程的感知和理解状态,可以更好地理解学生的学习状态以提供更好的基于"情感触发"的认知和情感支持。并将情感学习本体和一个C语言程序设计领域知识本体以及反馈策略生成算法应用到一个以教学视频为主体学习资料的智能教学系统中。应用实例表明,该教学反馈策略生成算法能对学习者提供有效的认知反馈和情感反馈。

Instructional feedback strategy generation algorithm based on an emotion learning ontology

This paper studies how to solve the problem of emotion analysis and emotion feedback in instructional tutoring system. We construct an emotion learning ontology to describe the emotional concepts and the relationship among these concepts during the learning process, and we design an algorithm to select appropriate teaching feedback strategy on the basis of the emotion ontology.This algorithm can understand learners’situation and provide support without interaction with learners through questions and answers.The emotion ontology,a C programming ontology,and the algorithm are applied into an intelligent tutoring system which uses instructional videos as core materials.Application cases verify that the feedback strategy generation algorithm on the basis of the emotion learning ontology can provide appropriate cognitive feedback and emotional feedback to learners.
