Abstract:

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.

Key words: emotion learning ontology;emotion computing;teaching feedback strategy;intelligent tutoring system
