真实场景中AI生成文本的识别：语境性与矛盾
原标题：Contextuality and Contradictions: Exploring Real-World Identifications of AI-Generated Writing
AI 摘要
该研究分析了74名美国佛蒙特州高中生与本科生的问卷回答，以及2024年10月至2026年9月间英语维基百科编辑标记AI生成文本的11,882条记录，考察人们在真实场景中判定文本为AI生成时所依据的证据。研究发现，判定依据多样且相互矛盾：学生将中立、缺乏情感视为AI特征，维基百科编辑则将热情、推广语气视为AI特征；维基百科上标记理由的表述随时间缩短，越来越多编辑仅引用外部社区公告板而不指出文本特征。作者指出，判定AI的动机常源于语用失当感而非特定文本元素，将AI相似性视为脱离语境属性的检测工具可能大规模固化其训练语境的规范。

Contextuality and Contradictions: Exploring Real-World Identifications of AI-Generated Writing Abstract. As AI-generated content spreads into nearly every domain of human interaction, practices and discourses of AI detection, both formal and informal, have become an everyday part of how people interact with text and with each other. In this paper, we explore the real-world practices and discourses of AI identification that have emerged in response to a shifting discursive landscape where the hum
