用Hawkes过程模拟Twitter活动的图论方法

A Graph Approach to Simulate Twitter Activities with Hawkes Processes

Ao Qu, Ismael Lemhadri

摘要:

近年来,由于互联网的普及,社交媒体的快速增长已经见证。这一趋势带来了越来越多的兴趣,模拟社交媒体,可以提供有价值的见解,学术研究人员和企业。在本文中,我们提出了一个逐步的方法,使用霍克斯过程,一个自激活的随机过程,模拟Twitter的活动,并展示了如何利用这个模型来评估极其罕见的网络危机的机会。本研究的另一个目的是介绍一种新的策略,实现Hawkes过程的图结构。总的来说,我们打算将目前的霍克斯过程扩展到更广泛的场景,特别是通过结合实际的用户状态和用户之间的追随者互动来创建更逼真的Twitter活动模拟。

英文摘要:

The rapid growth of social media has been witnessed during recent years as a result of the prevalence of the internet. This trend brings an increasing interest in simulating social media which can provide valuable insights to both academic researchers and businesses. In this paper, we present a step-by-step approach of using Hawkes process, a self-activating stochastic process, to simulate Twitter activities and demonstrate how this model can be utilized to evaluate the chance of extremely rare web crises. Another goal of this research is to introduce a new strategy that implements Hawkes process on graph structures. Overall, we intend to extend the current Hawkes process to a wider range of scenarios and, in particular, create a more realistic simulation of Twitter activities by incorporating the actual user status and following-follower interactions between users.
