社交网络中谣言的演化

Rumor Evolution in Social Networks

Yichao Zhang, Shi Zhou, Jihong Guan, Shuigeng Zhou

摘要:

社交网络是谣言传播的主要渠道。以往的研究主要集中在静态的谣言传播。谣言的内容在整个传播过程中是不变的。事实上,谣言在其传播过程中不断演变,变得更短,更简洁,更容易理解和讲述。在一项早期的心理学实验中,研究人员发现谣言中大约70%的细节在前6次口对口传播\cite{TPR}中丢失。基于事实,我们研究了谣言在社交网络上的传播,其中谣言的内容被个体以一定的概率修改。在这种情况下,他们有两个选择,转发或修改。作为一个转发者,一个人直接向邻居传播谣言。相反,作为一个修正者,一个人在传播谣言之前会修正谣言。当谣言在社交网络上传播时,如无标度网络和小世界网络,如果谣言的修改者在网络中占主导地位,那么大多数个体实际上会被谣言的多次修改版本所感染。我们的观察表明,原始谣言可能会在传播过程中失去影响力。同样,一个真实的信息也可能变成谣言。我们的研究结果表明,谣言的演变不应该是一个可以忽略的问题,这可能会提供一个更好的理解谣言的产生和破坏。

英文摘要:

Social network is a main tunnel of rumor spreading. Previous studies are concentrated on a static rumor spreading. The content of the rumor is invariable during the whole spreading process. Indeed, the rumor evolves constantly in its spreading process, which grows shorter, more concise, more easily grasped and told. In an early psychological experiment, researchers found about 70% of details in a rumor were lost in the first 6 mouth-to-mouth transmissions \cite{TPR}. Based on the facts, we investigate rumor spreading on social networks, where the content of the rumor is modified by the individuals with a certain probability. In the scenario, they have two choices, to forward or to modify. As a forwarder, an individual disseminates the rumor directly to its neighbors. As a modifier, conversely, an individual revises the rumor before spreading it out. When the rumor spreads on the social networks, for instance, scale-free networks and small-world networks, the majority of individuals actually are infected by the multi-revised version of the rumor, if the modifiers dominate the networks. Our observation indicates that the original rumor may lose its influence in the spreading process. Similarly, a true information may turn to be a rumor as well. Our result suggests the rumor evolution should not be a negligible question, which may provide a better understanding of the generation and destruction of a rumor.
