摘要
分析了真实信息和谣言在传播结构和时序上的不均匀性,发现危机信息在社会传播网络上的传播规则是时变的.提出了时变传播规则下危机信息的ISKS-ISK两阶段传播模型.通过仿真发现,网络规模对危机信息传播影响很小,而初始传播节点数量、信息传播率、权威渠道发布真实信息的时间是影响危机信息传播速度和范围的主要因素.因此,从源头控制传播者数量、尽早通过权威渠道发布危机真实信息是减少危机中谣言危害的有效举措.
The ununiformity of the dissemination structure and timing of real information and rumors was analyzed,and it was found that the rules of the crisis information spreading on the social communication networks are time-varying.A two-stage crisis information propagation model named ISKS-ISK was established.The simulation results show that network size has little effect on the crisis information dissemination,while the number of the initial spreaders and the time when the authority channel started to propagate the real information have a great impact on the pace and scope of crisis information dissemination.Therefore,controlling the number of the rumor propagators from the source and making the authority channels release the real crisis information as soon as possible are very effective methods for reducing the threat of rumors.
