📝 摘要(中文)
人类社会交流中的情感和意图常通过隐性方式传达,缺乏系统的研究框架。本文提出隐性社会语境分析(MoCA),系统建模情感、意图和立场三个维度,构建了包含3108个多模态实例的高质量基准数据集。通过实验发现,现有的多模态大语言模型在此任务上表现不佳,提出的冲突驱动的溯因推理(CoDAR)框架显著提升了模型性能,但与人类推理仍存在较大差距。
🔬 方法详解
问题定义:本文旨在解决隐性社会语境分析的问题,现有方法在处理隐性信号时表现不佳,主要依赖显性线索,导致对潜在社会语境的理解不足。
核心思路:提出MoCA框架,通过冲突驱动的溯因推理(CoDAR)来建模观察到的表达与预期行为之间的认知冲突,从而推断隐藏的心理状态,增强模型对隐性信号的理解能力。
技术框架:整体架构包括数据收集、特征提取、冲突建模和推理四个主要模块。数据收集阶段构建高质量的多模态数据集,特征提取阶段利用深度学习技术提取多模态特征,冲突建模阶段分析表达与行为之间的差异,推理阶段进行心理状态的推断。
关键创新:最重要的技术创新在于引入了冲突驱动的溯因推理(CoDAR)框架,能够有效捕捉隐性社会语境中的认知冲突,与传统方法相比,提供了更深层次的理解。
关键设计:在模型设计中,采用了多模态融合技术,结合了文本、图像等多种信息源,损失函数设计上考虑了认知冲突的量化,网络结构上使用了改进的Transformer架构,以增强模型的推理能力。

📄 摘要(原文)
Human social communication, such as affection and intent, is often conveyed in highly implicit ways, where underlying meanings are expressed through indirect, socially and culturally grounded signals rather than explicit statements. Such implicit social contexts are pervasive in real-world interactions, yet there remains a lack of a formal and systematic framework for studying them. In this paper, we introduce Implicit Social Context Analysis (MoCA), a novel task that systematically models implicit social scenarios along three key dimensions: affection, intent, and stance. We construct a high-quality benchmark containing 3,108 multimodal instances collected from real-world sources, with fine-grained cognitive annotations revealing who expresses what toward whom, as well as how and why it is conveyed. Using the MoCA dataset, we show that state-of-the-art multimodal large language models struggle significantly with this task because of their reliance on explicit cues and limited ability to reason over latent social contexts. To address this challenge, we propose Conflict-Driven Abductive Reasoning (CoDAR), a novel framework that models the discrepancy between observed expressions and expected truthful behavior as cognitive conflict, thereby enabling the inference of hidden mental states. Extensive experiments demonstrate that CoDAR substantially improves model performance. Nevertheless, a large gap from human reasoning remains, highlighting the fundamental difficulty of implicit social understanding.
