摘要
【目的】研究媒体协同在话题传播中的作用机制,及其在引导和控制舆情话题传播方面的应用。【方法】采用模拟仿真方法,构建媒体协同作用下的舆情话题传播模型,分析发挥协同作用的媒体,及其作用时间点和作用时长对舆情话题传播的影响机制。【结果】仿真结果表明,相对于单个媒体,多个媒体构建的协作网络对话题传播有更强的促进作用,并且受媒体介入时间和媒体作用时长影响。【局限】仿真实验中,网民传播舆情的载体网络虽是现实网络,但是媒体协作网络和话题传播数据均来自于模拟仿真。【结论】媒体之间的协作关系是话题传播中媒体的重要表现形式,合理利用其协同作用有利于科学、高效地控制和引导舆情话题的传播。
[Objective] This paper aims to study the mechanism of media collaboration in topic propagation and its application in guiding and controlling the dissemination of public opinion topics.[Methods] Using the method of simulation,the model of public opinion topic propagation under the media synergy effect was constructed,and the influence mechanism of the medium that played synergy,and the time point and duration of its effect on the dissemination of public opinion topics were explored.[Results] The simulation results show that,compared to single media,the collaborative network constructed by multiple media plays a stronger role in promoting topic communication,and is affected by the media intervention time and the media duration.[Limitations] In the simulation experiment,the Internet public opinion carrier network is a real network,but the media collaboration network and topic communication data are all from simulation.[Conclusions] The collaboration between media is an important expression of media in the propagation of topics.The rational use of its synergies is conducive to controlling and guiding the dissemination of public opinion topics scientifically and efficiently.
