在社交网络中传播八卦

Spreading gossip in social networks

Pedro G. Lind, Luciano R. da Silva, José S. Andrade, Hans J. Herrmann

摘要:

我们研究了一个简单的模型,在社交网络中的信息传播,其中引入了两个量:传播因子,它测量一个给定的节点的邻居之间交换信息的平均最大分数,和所需的传播时间的信息,以达到这样的分数的节点。当信息涉及测量两个量的特定节点时,该模型可以被视为流言传播的模型。在这种情况下,我们将该模型应用于真实的经验网络的社会熟人和比较潜在的传播动力学与不同类型的无标度和小世界网络。我们发现,友谊连接的数量强烈影响被八卦的概率。最后,我们讨论如何扩展因子能够被应用到其他情况。

英文摘要:

We study a simple model of information propagation in social networks, where two quantities are introduced: the spread factor, which measures the average maximal fraction of neighbors of a given node that interchange information among each other, and the spreading time needed for the information to reach such fraction of nodes. When the information refers to a particular node at which both quantities are measured, the model can be taken as a model for gossip propagation. In this context, we apply the model to real empirical networks of social acquaintances and compare the underlying spreading dynamics with different types of scale-free and small-world networks. We find that the number of friendship connections strongly influences the probability of being gossiped. Finally, we discuss how the spread factor is able to be applied to other situations.
