摘　　要：针对网络谣言泛滥且难以识别、监管的现状,从话题扩散和群体行为交互两方面对网络谣言的传播进行协同研究,设计了网络谣言传播系统的计算实验模型,并从网民服务商监管、媒介数量和网民密度三方面进行了实验研究。结果表明:无监管系统中较易产生网络谣言和衍生话题;网络服务商的监管会导致更多网民了解相关信息,但会显著降低传谣者比率;应用媒介数量、网民数量与信息传播速度正相关,媒介越多,谣言初始传播速度越快,但不会影响系统稳定状态时各类网民的比例,网民密度越大,网络谣言扩散速度越快,谣言话题越易消退。Aiming at the situation that the internet rumors difficult to identify and supervise, the research on rumors fromthe co-evolution of topic spreading and collective behavior is designed. We construct a computational experiment model toresearch the rumor spreading system. Results show that no regulatory system is easy to produce internet rumors and derivedtopics; Internet supervision platform will lead to more users to know the rumor, but it will significantly reduce the rumorspreading ratio; more media, initial velocity of rumors spread more quickly, but will not affect the stability of the system andthe stable proportion of all kinds of users, users greater density, network rumor spreading faster, rumors topics more easy toresolve.
