用情绪风格分析议会辩论，发现以色列政坛情感极化逐年加剧
Unveiling Affective Polarization Trends in Parliamentary Proceedings
- 以情绪三维度量化话语极化，不依赖立场分歧
- 政府与反对派发言情绪风格差异显著，且极化趋势持续上升
- 适用于政治话语分析、社会情绪监测的研究者
近年来全球范围内极化言论日益增多。本文提出一种新方法，通过情感风格而非意识形态差异来量化极化程度。基于效价、唤醒度和支配感三个维度，检测情绪性话语信号，并以此操作化情感极化概念。将该方法应用于近期发布的希伯来语议会记录数据集（以色列议会，Knesset），发现政府成员与反对派成员的发言情绪风格存在显著差异，且情感极化水平随时间显著上升。
原文摘要 · Abstract (English)
Recent years have seen an increase in polarized discourse worldwide, on various platforms. We propose a novel method for quantifying polarization, based on the emotional style of the discourse rather than on differences in ideological stands. Using measures of Valence, Arousal and Dominance, we detect signals of emotional discourse and use them to operationalize the concept of affective polarization. Applying this method to a recently released corpus of proceedings of the Knesset, the Israeli parliament (in Hebrew), we find that the emotional style of members of government differs from that of opposition members; and that the level of affective polarization, as reflected by this style, is significantly increasing with time.
