从情绪场域到话题引流:社交机器人传播虚假信息的双重机制
From Emotional Fields to Topic Engagement:The Dual Mechanisms of Social Bots in Disseminating Misinformation
摘要
Abstract
This study investigates the intrinsic mechanisms of social bots in disseminating misinformation from the dual perspectives of emotional fields and content topics.Drawing on a large-scale dataset of misinformation on Weibo,and employing methods including machine learning,zero-shot sentiment classification,BERTopic,and negative bino-mial regression,this research explores how social bots participate in misinformation propagation through dual path-ways:group emotional fields and topic engagement heat.Key findings include:1)social bots tend to engage more ac-tively with public issues that have high social influence or are prone to controversy;2)the involvement of bots signifi-cantly increases emotional entropy,thereby enhancing the diversity of collective emotional expression;3)emotional po-larization is more likely to emerge as a natural outcome of human user interaction rather than being directly triggered by bots;4)both emotional entropy and emotional polarization exhibit dual effects and topic heterogeneity in influencing the virality of misinformation.This study provides a dual-dimensional analytical framework for understanding misinforma-tion dissemination mechanisms in the era of human-bot symbiosis.关键词
