Abstract
In order to build the intelligent tutoring system, according to the basic theory of emotional psychology, the emotion mathematical model and the personality-moods-emotions multilayer model are used in this paper. By analyzing facial emotions, body emotions of the learner and the difficulty level of knowledge, we use the advantage of Credal networks to deal with uncertainty and ambiguity of data and information in the system to construct the relationship between learning emotions and learning effects, Therefore, we build intelligent tutoring system based on Credal networks and learning emotions. Experimental results show that the system can remind learners to pay attention to the knowledge and change the teaching strategies and knowledge structure change negative emotion into positive emotion continuously in the learning process. So it can improve the level of intelligent of the network tutoring system.
