摘　　要：【目的/意义】研究舆情在可调聚类系数的加权无标度BBV网络中的传播机制,为控制舆情发展提供参考。【方法/过程】在经典BBV网络的基础上加入三角连接,使得原有网络模型具有可调节聚类系数这一特性,并引入SIR模型,通过节点之间边的动态权重值来决定网络中三种状态之间的转换概率。【结果/结论】本文BBV模型中节点度分布、点强度分布和边权分布整体上满足幂律分布,三角连接率的大小可以直接影响网络模型聚类系数的大小,模型中节点度与节点强度二者满足一定的线性关系。三角连接的引进可以有效提高网络中的聚类系数,可以满足大范围调节聚类系数的网络建模。【Purpose/significance】To study the propagation mechanism of public opinion in the BBV network with adjustable clustering coefficients, and provide a powerful reference for controlling the development of public opinion.【Method/process】Based on the classical BBV network, triangular connection is added to make the original network model have the property of adjustable clustering coefficient. SIR model is introduced to determine the transition probability between the three states in the network by the weight value of the edges between nodes.【Result/conclusion】The distribution of node degree, point strength and edge weight in the model satisfy the power law distribution. The size of p value can directly affect the size of clustering coefficient of network model. The node degree and node strength in the model satisfy a certain linear relationship. The introduction of triangular connection can effectively improve the clustering coefficient in the network.With the increase of triangular connection probability p, it can resist the propagation of bad information to a certain extent.
