摘要：People are hungry for information about the emergency event, and are also inadvertently become unconfirmed information disseminator. To solve this problem, this paper proposes an unconfirmed information diffusion control strategy (UCID). Firstly, it filters the unconfirmed information propagate users sequence by the topic model, and then combines the node position function and the number of users directed spread unconfirmed information to calculate the score, and the sore level represents degree of important in the process. In the next step, we control the high score users to reduce unconfirmed information coverage, and compare the results with classical algorithms PageRank. This strategy has high differentiation degree to the key nodes, which is advantageous to control the information propagation rapidly
