Abstract: In view of the social network influence maximization problem in the field of communication research, the node itself has emotion to ignore the influence of the event propagation, this paper puts forward the social network communication model based on emotion, Emotion Independent Cascade model（E-IC）. About E-IC model, this paper emphasizes the emotional impact of basic problems（Influence Maximization Problem based on Emotion, IMPE）. In the entire spread process, this paper combines the calculated value of user’s location, the calculated value of rear emotion and interactive probability value. This paper demonstrates and confirms that the social network communication model based on emotional problem is NP-hard problem, and gives EMS-Greedy approximate algorithm. The model parameters are adjusted on the training set to make the propagation process more consistent with the propagation law. The effectiveness of the E-IC model is verified by experiments on large-scale real data sets. Compared with other models, E-IC model expands its range by about 7%.
