自杀是现代世界的主要原因之一。在这个数字时代，人们越来越多地使用社交媒体来表达自己，并经常使用这些平台来表达自杀意图。各种研究已经在受控环境中检查了自杀意图的行为标记，但尚未探索这些标记是否会推广到社交媒体上表达的自杀意图。在这项工作中，我们着手研究社交媒体视频上表达的与自杀意图相关的多模式行为标记。我们在识别自杀企图风险较高的个体的背景下探索言语、听觉和视觉行为标记。我们的分析表明，频繁的沉默、耷拉着肩膀、快速的手部动作和脏话是表明自杀意图的主要多模式行为标志1。
Suicide is one of the leading causes of death in the modern world. In this digital age, individuals are increasingly using social media to express themselves and often use these platforms to express suicidal intent. Various studies have inspected suicidal intent behavioral markers in controlled environments but it is still unexplored if such markers will generalize to suicidal intent expressed on social media. In this work, we set out to study multimodal behavioral markers related to suicidal intent when expressed on social media videos. We explore verbal, acoustic and visual behavioral markers in the context of identifying individuals at higher risk of suicidal attempt. Our analysis reveals that frequent silences, slouched shoulders, rapid hand movements and profanity are predominant multimodal behavioral markers indicative of suicidal intent1.
