我们开发了一种广泛适用的带有吸引子的共同演化潜在空间网络(CLSNA)模型,其中节点代表假设位于未知潜在空间中的个体社会参与者,边缘代表参与者之间特定交互的存在,并且在潜在水平中添加吸引子以捕获吸引力和排斥力的概念。我们应用 CLSNA 模型来了解美国政治在社交媒体上的党派极化的动态,我们预计共和党和民主党将越来越多地与自己的政党互动,并脱离对手政党。利用社交媒体平台 Twitter 和 Reddit 的纵向社交网络,我们分别量化了政治精英和公众中积极(有吸引力)和消极(排斥)力量的相对贡献。
We develop a broadly applicable class of coevolving latent space network with attractors (CLSNA) models, where nodes represent individual social actors assumed to lie in an unknown latent space, edges represent the presence of a specified interaction between actors, and attractors are added in the latent level to capture the notion of attractive and repulsive forces. We apply the CLSNA models to understand the dynamics of partisan polarization in US politics on social media, where we expect Republicans and Democrats to increasingly interact with their own party and disengage with the opposing party. Using longitudinal social networks from the social media platforms Twitter and Reddit, we quantify the relative contributions of positive (attractive) and negative (repulsive) forces among political elites and the public, respectively.
