以2014年“福喜肉”舆情事件为例,剖析该舆情媒体合作网络的结构特征、分析媒体在网络中的优越性与特权性、探讨各子群内部及子群之间的关系等,分别进行密度、平均最短路径、中心性、度分布、块模型等分析。研究发现,在具有无标度特性的媒体合作网络中,核心媒体推动着舆情信息大范围扩散。研究还发现在媒体合作网络中各节点、子群的结构并不对等,在舆情监控过程中应重点监控集散节点及群体,以引导舆情良性发展。
Taking the case of “Fuxi Meat” in 2014 as an example, this paper analyzes the structural features of the public opinion media cooperation network, analyzes the superiority and privilege of the media in the network, and discusses the relations among subgroups and subgroups , Respectively, density, average shortest path, center, degree distribution, block model analysis. The study found that in the media network with scale-free characteristics, core media promoted the widespread spread of public opinion information.

In the public opinion monitoring process, the nodes and groups should be supervised to guide the sound development of public opinion.
