摘要：

Choosing the right time to intervene public opinion dissemination is of great significance to the control of public opinion in online social networks (OSN). The key factors affecting the control of public opinion dissemination, such as user' network status, social strengthening effect and users' perception value, are analyzed. Aimed to identify the reasonable timing for intervention, a dissemination and control model of public opinion based on users' relative weight is constructed. Based on this model, simulation researches are carried out in two types of OSN. The results show that public opinion dissemination is closely related to the initial disseminator' network status; there exits a key phase transition point, which is related to timing of intervention in open OSN; users' activity decreases with the increase of the social strengthening effect's intensity, also decreases with the advance of intervention, and there exits an effective interval for intervention; the cost of "contrary to popular will" should be an important index for timing of intervention. Finally, the corresponding countermeasures for choosing the right time to intervene in reality are proposed. © 2019, Editorial Board of Journal of Systems Engineering Society of China.
