两层无标度网络谣言传播模型仿真研究

Simulation Investigation of Rumor Spreading Model Base on Two-layer Scale-free Networks

人际关系网络是谣言人际传播的载体,将媒体从人际关系网络中分离出来,利用可变聚类系数无标度网络和SIQR传播模型建立了谣言的两层传播模型,并制定了谣言在两层模型上的传播规则及相应算法。在仿真实验中,利用多Agent仿真平台Netlogo4.0.2分析了新模型中与媒体层相关的3个参数谣言激发数、媒体谣言传播率以及节点覆盖度的变化对人际关系网络中谣言传播的影响,发现提高媒体对谣言的敏感度、规范媒体职业操守、扩大媒体的传播范围有利于抑制人际关系网络中谣言的传播。

Relationship network is a carrier of rumor spreading. Separating the media from the relationship network, a two-tier rumor spreading model was proposed based on tunable clustering scale-free network and SIQR spreading model. Meanwhile the rumor spreading rules of the new model were developed. In simulation experiments, the influence associated with the three parameters of the media layer was analyzed by using the Mult-Agent system Netlogo4.0.2. It is found that improving the sensitivity of the media, regulating media ethics and expanding the scope of the media can curb the spread of rumors.
