Abstract：In this project， focusing on the scientific problem of group behavior formation and interactive principles， we study the group behavior and group emotion theory in the online social networks. In the year 2013， the project team developed the research mainly on four aspects. On the group aggregation principles and modeling methods aspect， aiming at incentive factors of group aggregation， we studied the topic aggregation in Weibo， detection of advertising users， and malicious user mining in SN. Aiming at group behavior attributes and common security requirements， we studied the group privacy protection policies and mechanisms. On the aspect of group behavior evolution， we studied the communication alert problem in the Weibo. On the multi-dimension attributes based emotion aspect， we studied multi-attributes and multi-dimension statistics characteristics of individual emotions from the relationship of individual personality， mentality， and background. On the group emotion formation principle base group emotion evolution calculation aspect， we studied the quantization of group emotion position， discovery of group emotion， multi-attributes mining of individual behavior information based on heterogeneous networks. Based on the research on the above four aspects， the research team published 28 papers， including 7 SCI indexed papers and 15 EI indexed paper， and 1 book. As to the patent aspect， we applied for 4 items and got 1 granted patent.
