DREAMS: 基于社会交换理论的社交媒体虚假信息互动建模

DREAMS: A Social Exchange Theory-Informed Modeling of Misinformation Engagement on Social Media

University of Technology Sydney(技术科技大学)

AI总结:

DREAMS基于社会交换理论,通过序列到序列建模提升社交媒体虚假信息互动预测精度,达到43.6%的性能提升。

摘要:

社交媒体互动预测是计算社会科学中的核心挑战,尤其是在理解用户如何与虚假信息互动方面。现有方法往往将互动视为同质的时间序列信号,忽略了塑造虚假信息传播的异质性社会机制和平台设计。在本工作中,我们提出问题:"神经网络架构能否仅从行为数据中发现社会交换原则?"我们引入DREAMS(解耦表示和周期性适应的社交媒体虚假信息互动建模框架),这是一个基于社会交换理论的框架,将虚假信息互动建模为动态的社会交换过程。与其将互动视为静态结果,DREAMS将其建模为序列到序列的适应问题,其中每个动作反映用户努力与社会奖励之间的演变谈判,受平台上下文影响。它整合了适应机制,以学习情感和上下文信号如何随时间及跨平台传播。在涵盖7个平台和237万条帖子的跨平台数据集上,DREAMS在预测虚假信息互动方面实现了最先进的性能,达到平均绝对百分比误差为19.25%。这比最强基线提高了43.6%。除了预测收益外,该模型揭示了与社会交换原则一致的跨平台模式,表明整合行为理论可以增强在线虚假信息互动的经验建模。源代码可在:https://github.com/ltian678/DREAMS获取。

英文摘要:

Social media engagement prediction is a central challenge in computational social science, particularly for understanding how users interact with misinformation. Existing approaches often treat engagement as a homogeneous time-series signal, overlooking the heterogeneous social mechanisms and platform designs that shape how misinformation spreads. In this work, we ask: ``Can neural architectures discover social exchange principles from behavioral data alone?'' We introduce \textsc{Dreams} (\underline{D}isentangled \underline{R}epresentations and \underline{E}pisodic \underline{A}daptive \underline{M}odeling for \underline{S}ocial media misinformation engagements), a social exchange theory-guided framework that models misinformation engagement as a dynamic process of social exchange. Rather than treating engagement as a static outcome, \textsc{Dreams} models it as a sequence-to-sequence adaptation problem, where each action reflects an evolving negotiation between user effort and social reward conditioned by platform context. It integrates adaptive mechanisms to learn how emotional and contextual signals propagate through time and across platforms. On a cross-platform dataset spanning $7$ platforms and 2.37M posts collected between 2021 and 2025, \textsc{Dreams} achieves state-of-the-art performance in predicting misinformation engagements, reaching a mean absolute percentage error of $19.25$\%. This is a $43.6$\% improvement over the strongest baseline. Beyond predictive gains, the model reveals consistent cross-platform patterns that align with social exchange principles, suggesting that integrating behavioral theory can enhance empirical modeling of online misinformation engagement.
