Abstract: On online social networks, follow-ship network among users underlies the diffusion dynamics of messages; meanwhile, the structure of underlying social network determines the visibility of messages and forwarding activities in the diffusion process. Taking SinaWeibo as an example, this paper focuses on multiple exposure phenomena in information diffusion, and investigates the patterns and regularities of users?? forwarding behavior among multiple exposures combined with the structure of follow-ship network. This paper analyzes the “forwarding whom” problem of users among multiple exposures in information diffusion, aiming to model and predict the forwarding behavior of individuals, combining content features, network structure, temporal and historical information. The experimental results demonstrate that the new method achieves a high accuracy of 91.3%.

Key words: online social network, information diffusion, multiple exposures, forwarding whom
