Exploiting the topology property of social network for rumor detection

Information credibility gradually shown its significant influence on social networks with high propagation ability and low confidence threshold, leading to the crucial work of identifying rumors. In this paper, we address the special characteristics of Weibo, the most popular microblogging service in China like Twitter, and proposed a general framework to assess the credibility of information. Specially, we analyze the specific topology-related properties of user network, and confirm the impact on credibility evaluation. We use features extracted from the microblogs, from the text of the reviews, and from the network structures. To explore the effectiveness of our approach, we conduct the experiment based on an extensive set of data provided by the community of management center in Weibo. Our results reveal that features considered in previous studies achieve a better performance with the consideration of new features we proposed. We believe the work in this paper open new dimensions in analyzing online disinformation.
