摘要
根据网络论坛的信息传播规律和用户交互特性,提出了一个基于节点影响力的离散时间观点传播与舆情形成模型。在该模型中,节点具有自我影响力和观点值,并且节点影响力被定义为网络中边的权值,节点在每一个周期内重新分配权值并更新它们的观点。节点观点收敛于某一定值时,形成网络舆情。仿真结果表明,所提模型可以准确地体现节点观点的动态交互特性和收敛特征,并可为舆情传播趋势的预测研究提供依据。
According to the information dissemination and the interaction characteristics of users for online forums, a discrete time model was proposed for opinion propagation and public opinion formation based on the node influence. In the model, every node has the opinion and the influence which is defined as the weight of network, and the nodes will re- distribute the weights and update their opinions during the each period. When the opinion of nodes converges to a cer- tain value,the public opinion will be formed. The simulation results show that this model can emulate accurately the characteristics of interation and convergence. Besides, the results can provide the reference for the prediction of public o- pinion propagation.
