基于S IR模型的社交网络推手节点发现及信息传播抑制
DISCOVERY OF PUSHING HANDS NODE IN SOCIAL NETWORKS BASED ON SIR MODEL AND INFORMATION DISSEMINATION RESTRAINT
摘要
Abstract
Pushing hands node plays a very important role in social networks information dissemination.We introduced the“pushing hands node”concept into traditional SIR model,studied the dissemination law of the hot topics caused by such kind of nodes in networks and their influence and control on social network information dissemination.Using YouTube data to build a social network topology,we found in experiment that when the node dissemination probability was greater than 0.7,it could be set as the pushing hands node,and that the target immune algorithm could be used for restraining information dissemination.While the entire information immunisation of the dissemination node in social networks was greater than 0.2,it could effectively inhibit the information dissemination.This value is the parameter value of the important acquaintance immunisation strategy used to suppress the information dissemination.关键词
