摘　　要：为探究谣言在社交网络中的传播规律,以经典的IESR模型为基础,根据社交网络结构特征分析权威性效应、从众效应,以及好友亲密度对社交网络上谣言传播的不同作用,建立用户状态转移的非一致性概率函数,提出一种谣言传播模型ACI-IESR(authority_conformity_intimacy-IESR)。在仿真网络和真实网络中进行仿真实验,分析3种因素如何影响社交网络中的谣言传播。实验结果表明,权威性效应及从众效应能加速谣言在社交网络中扩散和消散,增大谣言的扩散范围。用户与好友之间的亲密度关系,使谣言传播的范围更广。To explore the spread of rumors in social networks,based on the classic IESR model,three factors that affect the spread of rumors on social network were analyzed according to the structural characteristics of social networks,including the authority effect,herd effect,and the intimacy of friends,establishing the inconsistency of user state transfer probability functions,a rumor propagation model called ACI-IESR(authority_conformity_intimacy-IESR)was proposed.Simulation experiments were carried out in the simulated network and the real network to analyze how three factors affect the spread of rumors in social networks.The results that the authority effect and herd effect can accelerate the spread and dissipation of rumors in social networks are showed by experiments.And the intimacy relationship between users and friends makes the spread of rumors wider.
