研究与开发一种基于耦合网络的RD-IHSAT网络谣言传播模型韩一士,徐雨欣,卢甜甜(浙江警察学院,浙江杭州310053)摘要:为探究谣言在社交网络中的传播规律,基于耦合原理,构建由巴拉巴西-阿尔伯特(Barabási-Albert,BA)无标度网络与瓦茨-斯特罗加茨(Watts-Strogatz,WS)小世界网络组成的沉默者、辟谣者、无知者、犹豫者、传谣者、铁杆传谣者、疲惫者(reticent,debunker,ignorant,hesitated,spreader,adherent,tired,RD-IHSAT)谣言传播模型。该模型在易感者、感染者、移出者(susceptible,infective,removal,SIR)模型的基础上引入兴趣衰弱机制、感知社会共识机制、沉默与反沉默的螺旋等因素,并融入犹豫者、铁杆传谣者、沉默者、辟谣者等角色,使其更加逼近真实情形。仿真结果显示,耦合网络极大地促进了谣言的传播,不仅加快谣言爆发速度,而且扩大谣言传播规模;提高对犹豫者的辟谣概率能够极为显著地抑制谣言规模,是控制谣言传播的最有力因素;仅降低谣言传播率对谣言控制作用较小;提高沉默群体的比例是遏制谣言传播的关键一环;对辟谣时滞的把控极大地影响了辟谣效果。关键词:谣言传播;耦合网络;兴趣衰弱;社会共识;沉默的螺旋;RD-IHSAT模型中图分类号:TP391.9文献标志码:Adoi:10.11959/j.issn.1000-0801.2023023AmodelofRD-IHSATrumordisseminationbasedoncouplingnetworkHANYishi,XUYuxin,LUTiantianZhejiangPoliceCollege,Hangzhou310053,ChinaAbstract:Toexplorethespreadofrumorsinsocialnetwork,basedontheprinciplesofcouplingnetwork,themodelofRD-IHSATwasestablishedonBarabási-Albert(BA)scalefreenetworkandWatts-Strogatz(WS)smallworldnetwork.TheclassicmodelofSIRwasoptimized,bycombiningitwiththreeconcerns,theinterestdecay,thesocialconsensusandthespiralofsilenceeffect,andaddingfourroles,hesitated,adherent,reticentanddebunker.Resultsofnumericalsimulationsareasfollows:aninformationoutbreakcanbetriggeredbycouplingnetwork,notonlythespreadingspeedbutthescaleaswell;thedisseminationcanbemarkedlysuppressedwhentheprobabilityofru-mor-refutingforthehesitatedandspreadersarises;thechancesoftransitionfromspreaderstoadherentsdrop;in-creasingtheproportionofsilentgroupsisakeypartofcurbingthespreadofrumors;thecontrolofthetimelaginrefutingrumorswillgreatlyaffe...
