随着政治动荡加剧线上话语讨论，Bluesky已成为重要的政治讨论与公众反应平台。本研究考察Bluesky上与特朗普政府相关的美国政策动态的大规模话语内容。我们利用历史检索API，收集了2019年至2026年间所有匹配“特朗普”及相关关键词的帖子，共得到3850万条帖子。我们采用大语言模型（LLM）辅助的聚类流程，并结合人工验证，识别出英文帖子中的14个可解释主题域，以及2025年1月20日至2026年5月1日期间签署的258项行政命令（EO）中的19个主题类别。研究发现，Bluesky话语中的主导主题包括行政治理、政治身份与国家安全，行政命令中的反复出现主题包括行政特别工作组、边境执法与外交政策；我们还发现议题关注度的持续性与波动性存在显著差异，且负面情绪占比随时间推移不断上升。该数据集与相关资源可在指定公开URL获取。
英文摘要
As political disruption intensifies online discourse, Bluesky has become an important platform for political discussion and public reaction. In this study, we examine large-scale discourse on Bluesky related to U.S. policy developments associated with the Trump administration. Using the historical retrieval API, we collected all available posts matching Trump and related keywords from 2019 to 2026, yielding 38.5 million posts. We leverage a large language model (LLM)-assisted clustering pipeline, combined with human validation, to identify 14 interpretable thematic domains in English-language posts and 19 thematic categories across 258 executive orders (EOs) signed between January 20, 2025, and May 1, 2026. Our findings identify several dominant themes in Bluesky discourse, including executive governance, political identity, and national security, as well as recurring themes in EOs, including executive task forces, border enforcement, and foreign policy. We also find substantial variation in the persistence and volatility of issue attention, accompanied by an increasing proportion of negative sentiment over time.
