尽管存在衡量行动者制定政策、媒体和立法议程的策略,但政治学家缺乏一种方法来识别和准确衡量两个人谈话时隐藏在表面之下的另一种议程设置形式。在辩论、审议和讨论等互动中,行动者可以通过将其他人的注意力转移到他们喜欢的主题上来设定议程。在这篇文章中,我使用了一个话题模型,它可以定位互动中发生话题转移的位置,以衡量参与者的相对议程设置能力。验证表明,该模型准确地识别主题转移和推断连贯的主题。三个实证应用也验证了不同政治环境中的议程设置措施:美国总统辩论,面对面审议和在线讨论。这些应用程序表明,成功地设置议程可以塑造互动的结果,这表明继续研究这种形式的议程设置的重要性。
Although strategies exist to measure actors' efforts to set policy, media, and lawmaking agendas, political scientists lack a method for identifying and accurately measuring another form of agenda setting that lies under the surface anytime two people talk. Within interactions, such as debates, deliberations, and discussions, actors can set the agenda by shifting others' attention to their preferred topics. In this article, I use a topic model that locates where topic shifts occur within an interaction in order to measure the relative agenda‐setting power of actors. Validation exercises show that the model accurately identifies topic shifts and infers coherent topics. Three empirical applications also validate the agenda‐setting measure within different political settings: U.S. presidential debates, in‐person deliberations, and online discussions. These applications show that successfully setting the agenda can shape an interaction's outcomes, demonstrating the importance of continued research on this form of agenda setting.
