Abstract: According to OCC model, an emotional recognition model based on cognition and appraisal theory was proposed. The expectation probability of events in the educational environment was determined by reasoning with a fuzzy way. A dynamic bayesian network was also built to evaluate and simulate the learning process and the result shows the model's validity and rationality. Thus this paper's work has provided a novel emotion recognition model and frame to make e-learning systems more emotional intelligent.
