社会互动的可预测性

Predictability of social interactions

Kevin S. Xu

摘要:

预测人与人之间的社会互动的能力具有深远的应用,包括有针对性的营销和预测信息扩散和疾病传播。以前的研究表明,一个人在任何给定时间的位置是高度可预测的。这项研究探讨了人与人之间的社会互动的可预测性,以确定互动模式是否具有类似的可预测性。我发现,一个人互动的地点和时间是高度可预测的;然而,与这个人互动的另一个人却不那么可预测。此外,我表明,知识的位置和时间的互动几乎没有影响的可预测性的其他人。最后,我证明了一个简单的马尔可夫链模型是能够实现接近上限的预测下一个人与一个给定的个人将进行交互。

英文摘要:

The ability to predict social interactions between people has profound applications including targeted marketing and prediction of information diffusion and disease propagation. Previous work has shown that the location of an individual at any given time is highly predictable. This study examines the predictability of social interactions between people to determine whether interaction patterns are similarly predictable. I find that the locations and times of interactions for an individual are highly predictable; however, the other person the individual interacts with is less predictable. Furthermore, I show that knowledge of the locations and times of interactions has almost no effect on the predictability of the other person. Finally I demonstrate that a simple Markov chain model is able to achieve close to the upper bound in terms of predicting the next person with whom a given individual will interact.
