基于关键节点识别的社交网络舆情控制策略研究
Research on Social Network Public Opinion Control Strategy Based on Key Node Identification
摘要
Abstract
Effective identification of key nodes in social networks plays an important role in the control and guidance of public opinion.Aiming at the problem of social network public opinion dissemination,a control method based on key node identification is proposed.Firstly,a key node identification method based on dual index Shannon entropy is designed.Considering the importance of nodes in the global network and local network topology,the intermediate number and struc-tural hole constraint coefficient index are used as the information function to construct the node distribution probability,and then the node information entropy is calculated to identify the key nodes in the public opinion dissemination according to the size of the information entropy.Secondly,the effectiveness of the key node identification method is verified through simulation experiments,and the role of the identified key nodes in the public opinion communication is analyzed based on the SIR model.Finally,the control strategy is given.The experimental results show that this method can effectively identify the"bridge"node in the network except the network center node.In the public opinion propagation simulation,the speed and range of public opinion propagation are significantly reduced after adding the control bridge node,and the public opinion control effect is optimal when the number of key nodes is within the range of 2%～3%,and the marginal utility beyond this range is significantly reduced.关键词
