【摘要】:【目的/意義】近年來微信已成為民眾社交的首要平臺,同時也逐漸成為謠言傳播的主陣地,但目前針對微信謠言傳播的研究尚不多見!痉椒/過程】將微信網(wǎng)絡劃分為朋友圈網(wǎng)絡、群網(wǎng)絡和公眾用戶網(wǎng)絡,生成了微信謠言傳播加權(quán)有向三層網(wǎng)絡,在此網(wǎng)絡基礎(chǔ)上構(gòu)建了基于興趣衰減效應的線性閾值謠言傳播模型,并利用多主體仿真平臺Netlogo對該模型進行仿真!窘Y(jié)果/結(jié)論】研究發(fā)現(xiàn),微信群的存在改變了個人用戶網(wǎng)絡節(jié)點的度分布,且導致當節(jié)點信任度較低時微信網(wǎng)絡比微博類網(wǎng)絡更有利于謠言的傳播;節(jié)點信任度與謠言的傳播力度顯著正相關(guān);增大謠言傳播閾值和減小謠言傳播興趣值,能有效抑制謠言的傳播。
[Abstract]:[Objective] / significance in recent years WeChat has become the most important social platform, also gradually become the main position of the spread of rumors, but the current research on WeChat rumor is stillrare. [method] / process divides the network into the circle of friends of WeChat network, cluster network and public network users, WeChat generated rumors spread weighted directed three layer network, based on the network to build a linear threshold rumor spreading model based on interest attenuation effect, and the use of multi agent simulation platform Netlogo to simulate the model. [Conclusion] the results / study found that WeChat group changed the distribution of individual users of the network nodes, and lead when spread the node trust is lower than micro-blog WeChat network network is more conducive to rumors; significant positive correlation with the node trust rumors spread rumors spread and increase efforts; reduce the threshold of rumors The spread of interest can effectively suppress the spread of rumors.
