The purpose of this research is to enhance our understanding of homophilic behaviors—where individuals prefer to associate with others like themselves—on Twitter, particularly focusing on how these behaviors vary across different political affiliations. While a general increase in homophily is a well-documented phenomenon in social networks, its expression within the diverse political contexts on Twitter remains underexplored. This study seeks to understand how political alignment influences homophily and its possible role in reinforcing extreme viewpoints. In particular, the research examines the patterns of interaction within political communities on French Twitter, delineating between right-wing, left-wing, and centrist groups. The findings reveal a significant pattern: right-wing groups demonstrate a marked increase in homophily over time, suggesting a stronger predilection for in-group interaction when compared with their centrist and left-wing counterparts. In addition, the study monitors the evolution of follower networks among these political clusters, providing insights into the shifting popularity of political parties within each group. By analyzing the social connections within these clusters, the study offers a detailed perspective on the dynamics of political homophily on Twitter and how it evolves, informing our understanding of political communication and group behavior in the digital age.

与左翼和中间派用户相比，法国右翼 Twitter 用户表现出日益增长的同质性

这项研究的目的是增强我们对 Twitter 上同质行为（个人更喜欢与与自己相似的人交往）的理解，特别关注这些行为在不同政治派别之间的差异。虽然同质性普遍增加是社交网络中一个有据可查的现象，但它在 Twitter 上不同政治背景下的表达仍未得到充分探索。本研究旨在了解政治联盟如何影响同质性及其在强化极端观点方面可能发挥的作用。该研究特别考察了法国推特上政治群体内部的互动模式，划分了右翼、左翼和中间派团体。研究结果揭示了一个重要的模式：随着时间的推移，右翼群体的同质性显着增加，这表明与中间派和左翼群体相比，他们更倾向于群体内互动。此外，该研究还监测这些政治群体中追随者网络的演变，为了解每个群体中政党受欢迎程度的变化提供见解。通过分析这些集群内的社会联系，该研究提供了关于 Twitter 上政治同质性动态及其演变的详细视角，帮助我们理解数字时代的政治传播和群体行为。
