People hold all kinds of positive and negative feelings against one another. Social networking online serves as a platform for showcasing such relationships, whether friendly or unfriendly, like or dislike, trust or distrust, cooperation or dissension. These types of interactions result in the creation of signed social networks (SSNs). Although negative signs typically dominate the final user decision in most real applications, it cannot be directly propagated between users like positive signs. The study on negative sign prediction is still in its early stages. There is a difference between the value of negative signs and the availability of these links in real data sets. It is therefore normal to analyze whether one can automatically predict negative signs from the widely available social network data. In this paper, we propose a novel negative sign prediction model which includes negative sign related features from various categories to predict negative sign in signed social network. An extensive set of experiments is carried out on real-world social network datasets which demonstrate that the proposed model outperforms the existing method in predicting negative signs in terms of accuracy and F1 score by 4% and 14% respectively.
