- 适合关注社会运动、话语分析与数字公共领域的研究者阅读。
本项目提出一种建模#黑人命也是命（#BlackLivesMatter）相关社群中语义领导力的方法，基于对社交媒体及黑人推特结构的定性研究。我们设计了定制化的时间分段、社区聚类与跨时连接策略，并改进了先进的语义变迁检测与语义领导力推断方法。结果表明，布莱姆活动人士与进步派具有显著的话语领导地位，同时黑人名人也发挥重要作用。此外，保守派社群在该议题上表现出持续参与，暗示当前全国范围内“反觉醒”与“反批判种族理论”法案出台的背后存在更复杂的社会互动机制。
原文摘要 · Abstract (English)
In this project, we describe a method of modeling semantic leadership across a set of communities associated with the #BlackLivesMatter movement, which has been informed by qualitative research on the structure of social media and Black Twitter in particular. We describe our bespoke approaches to time-binning, community clustering, and connecting communities over time, as well as our adaptation of state-of-the-art approaches to semantic change detection and semantic leadership induction. We find substantial evidence of the leadership role of BLM activists and progressives, as well as Black celebrities. We also find evidence of the sustained engagement of the conservative community with this discourse, suggesting an alternative explanation for how we arrived at the present moment, in which "anti-woke" and "anti-CRT" bills are being enacted nationwide.
