Research on CSER Rumor Spreading Model in Online Social Network.

In the field of rumor spreading, kill rumor is a very important concept. In the previous study of rumor spreading, only considering the rumor from the outside of the network, while ignoring the node itself has the discriminability. In this paper, a new CSER rumor propagation model is proposed and a kind of node with the ability of killing rumor is introduced in the model, that node is called rumor-killer. By means of complex network theory and mean-field method, we establish the differential equations of propagation dynamics. In this paper, the model is used to study the process of rumor spreading both in homogeneous network and heterogeneous network. Through theoretical analysis and experimental simulation, it is found that the node with the ability of killing rumor can mitigate the spreading rumor in the network. This conclusion provides us a new way to control the rumor spreading from the inside of network.
