Social network is a theoretical structure to analyze the relations between individuals, groups and organizations in the social science area based on graph theory, balance theory, social comparison theory and social identity theory. With the spread of Social Network Services (SNS), large volume of social data has been generated, and by analyzing the Social Networks and exploiting useful information extracted out of them, many domestic and foreign companies are improving the performance of various processes. In our lab, we are studying the techniques to maximize the influence of information by observing how information spreads out in social network. Furthermore, we are studying precise and accurate social recommender system, and SNS spam detection technologies by utilizing various features extracted out of social networks.
