AI总结:

针对现有视觉语言模型道德对齐研究模态单一、数据真实性不足的问题,提出基于真实数据、含13类道德主题与2481对标注图文的MORALISE基准,经19款主流VLM测试验证其能有效暴露模型道德缺陷。

摘要:

警告:本文包含有害语言与图像示例,建议读者酌情阅读。近年来,视觉语言模型凭借强大的多模态推理能力,在自动驾驶、医学分析等道德敏感领域展现出日益增长的影响力。随着这些模型被部署于高风险现实应用中,确保其输出符合人类道德价值观、处于道德边界之内至关重要。但现有道德对齐研究要么仅聚焦文本模态,要么严重依赖AI生成图像,导致分布偏差且真实性不足。为克服这些局限,我们提出MORALISE——一个采用经专家验证的多样化真实世界数据、用于评估视觉语言模型(VLM)道德对齐水平的综合性基准。我们首先基于Turiel的领域理论提出了包含13个道德主题的综合分类体系,覆盖日常生活中常见的个人、人际与社会道德领域。基于该框架,我们人工整理了2481对高质量图文对,每对均标注两类细粒度标签:(1)主题标注,明确被违反的道德主题;(2)模态标注,指明违规行为源自图像还是文本。评估环节设置了两项任务:道德判断与道德规范归因,用以评估模型对道德违规的感知能力及对道德相关内容的推理能力。对19款主流开源与闭源VLM的大量实验表明,MORALISE带来了显著挑战,暴露了当前最先进模型中持续存在的道德缺陷。完整基准已公开于https://huggingface.co/datasets/Ze1025/MORALISE。

英文摘要:

Warning: This paper contains examples of harmful language and images. Reader discretion is advised. Recently, vision-language models have demonstrated increasing influence in morally sensitive domains such as autonomous driving and medical analysis, owing to their powerful multimodal reasoning capabilities. As these models are deployed in high-stakes real-world applications, it is of paramount importance to ensure that their outputs align with human moral values and remain within moral boundaries. However, existing work on moral alignment either focuses solely on textual modalities or relies heavily on AI-generated images, leading to distributional biases and reduced realism. To overcome these limitations, we introduce MORALISE, a comprehensive benchmark for evaluating the moral alignment of vision-language models (VLMs) using diverse, expert-verified real-world data. We begin by proposing a comprehensive taxonomy of 13 moral topics grounded in Turiel's Domain Theory, spanning the personal, interpersonal, and societal moral domains encountered in everyday life. Built on this framework, we manually curate 2,481 high-quality image-text pairs, each annotated with two fine-grained labels: (1) topic annotation, identifying the violated moral topic(s), and (2) modality annotation, indicating whether the violation arises from the image or the text. For evaluation, we encompass two tasks, \textit{moral judgment} and \textit{moral norm attribution}, to assess models' awareness of moral violations and their reasoning ability on morally salient content. Extensive experiments on 19 popular open- and closed-source VLMs show that MORALISE poses a significant challenge, revealing persistent moral limitations in current state-of-the-art models. The full benchmark is publicly available at https://huggingface.co/datasets/Ze1025/MORALISE.
