我们研究了一个简单的社会网络中的信息传播模型，其中引入了两个量：传播因子，它度量了一个给定节点之间交换信息的邻居的平均最大可达性，以及信息到达这样一部分节点所需的传播时间。当信息涉及测量这两个量的特定节点时，该模型可以被视为八卦传播的模型。在此背景下，我们将该模型应用于真实的社会熟人经验网络，并比较了不同类型的无标度网络和小世界网络的潜在传播动力学。我们发现，朋友关系的数量对被八卦的概率有很大影响。最后，我们讨论了如何将扩散因子应用于其他情况。
We study a simple model of information propagation in social networks, where two quantities are introduced: the spread factor, which measures the average maximal reachability of the neighbors of a given node that interchange information among each other, and the spreading time needed for the information to reach such a 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.
