    Exploring Interactional Opinions and Status Theory for Predicting Links in Signed Network

    • With the wide spread and pervasion of social network, it brings more opportunities and novel problems for deep research on signed network, where link prediction is one of key problems in signed network. Interactional opinions and status theory are contributed to explain the construction and sign property of link relations, and provide theoretical principles for improving prediction quality. Therefore, this paper investigates link prediction problem in signed network from the perspective of interactional opinions and status theory, and constructs link prediction model by studying the strong correlation between two inducements and link relationship. Firstly, it explores interactional opinions to enhance the reliability of the decomposed matrix, and makes up for the limitations of status theory. Then, it models interactional opinions as enhanced reliability factor of matrix, and models status theory as the regularization terms. Finally, we construct the model of link prediction in signed network, namely MF-SI. Experimental results demonstrate that the model of MF-SI owns the best prediction quality compared with other baseline methods, which shows that the method of integrating interactional opinions with status theory implements link prediction in signed network.
