分析25年加拿大新闻报道，发现警方死亡事件中官僚视角占比近三倍于民众
Quantifying Media Representation Dynamics Across 25 Years of News Reporting on Policing-related Deaths
- 提出'视角差距'模型，量化媒体中各方声音比例
- 官方视角占比约3倍于民众，近年民众发声略有增加
- 适合关注媒体偏见、社会公平与警务问责的研究者
我们对过去25年间加拿大关于警务相关死亡事件的新闻报道进行了迄今为止最大规模的计算分析，涵盖4000篇报道。我们提出了一个基于社会学研究的新型计算模型——PerspectiveGap，用于衡量媒体报道中的视角分布。结果发现，警方死亡事件报道中，来自政府官员等体制内人员的视角平均占比接近民众（包括亲属、社区成员、目击者、律师及民权组织）的三倍；相当一部分报道未包含任何平民观点，尽管近年来平民声音有所上升。定性分析显示，官方叙述倾向客观程序化，而民众表述则情感色彩更浓。该框架可推广至其他司法辖区，为系统评估媒体如何建构警务与问责叙事提供可扩展方法。
原文摘要 · Abstract (English)
We perform the largest known computational analysis of Canadian news narratives about police-involved deaths, spanning 4,000 articles from the last quarter-century. We develop a novel computational model, PerspectiveGap, grounded in prior sociological work on media representation of policing. We find that reporting on police-involved deaths on average features perspectives from state bureaucrats at a rate nearly three times as much as perspectives from other members of the public, including relatives, community members, eyewitnesses, lawyers representing the family, or civil liberties groups. A considerable fraction of articles contain no points of view from civilian actors, though civilian representation has increased in recent years. Qualitatively, we find that state bureaucrats' accounts of these deaths tend to be clinical and procedural, while civilian discourse carries considerably more emotional valence. The PerspectiveGap framework developed here can be contextualized to other jurisdictions, offering a scalable approach for analyzing how media systems construct narratives around policing and accountability.
