基于极化度量的社区检测问题:Twitter 在西班牙 COVID-19 案例中的应用

Community detection problem based on polarization measures:an application to Twitter: the COVID-19 case in Spain

Inmaculada Gutiérrez, Juan Antonio Guevara, Daniel Gómez, Javier Castro, Rosa Espínola

AI总结:

本文提出基于 JDJpol 模糊极化度量的社区检测方法,并在西班牙 COVID-19 期间 Twitter 政治网络中验证,表明加入极化信息能改变社区划分。

摘要:

本文探讨了社交网络分析领域中一个最重要的课题:带有附加信息的社区检测问题。该附加信息由一个表示极化风险的模糊度量来建模。具体而言,我们关注在社区检测问题中考虑节点极化的问题。将此类信息添加到社区检测问题中使其更加现实,因为如果相应元素愿意维持和平对话,则社区更有可能被定义。极化能力基于与两个极点相关的 JDJpol 极化度量,通过一个模糊度量来建模。我们还提出了一种高效算法,用于寻找其元素不极化的群体。此后,我们研究一个真实案例,即从 Twitter 获取的网络,涉及几位有影响力的用户对西班牙政府的政治立场。我们分析了当添加与整个社会极化程度相关的附加信息时,所得分区如何变化。

英文摘要:

In this paper, we address one of the most important topics in the field of Social Networks Analysis: the community detection problem with additional information. That additional information is modeled by a fuzzy measure that represents the risk of polarization. Particularly, we are interested in dealing with the problem of taking into account the polarization of nodes in the community detection problem. Adding this type of information to the community detection problem makes it more realistic, as a community is more likely to be defined if the corresponding elements are willing to maintain a peaceful dialogue. The polarization capacity is modeled by a fuzzy measure based on the JDJpol measure of polarization related to two poles. We also present an efficient algorithm for finding groups whose elements are no polarized. Hereafter, we work in a real case. It is a network obtained from Twitter, concerning the political position against the Spanish government taken by several influential users. We analyze how the partitions obtained change when some additional information related to how polarized that society is, is added to the problem.
