摘要

模因是文本和图像的组合,通常具有幽默的性质。但是,情况可能并非总是如此,某些文字和图像的组合可能会描绘仇恨,被称为仇恨表情包。这项工作提出了一个多模态管道,将模因的视觉和文本特征考虑在内,以:(1)识别受到攻击的受保护类别(例如种族、性别等);(2)检测攻击的类型(例如蔑视,诽谤等)。我们的管道使用最先进的预训练视觉和文本表示,然后是一个简单的逻辑回归分类器。我们在仇恨模因挑战数据集上使用我们的管道,并为受保护的类别和攻击类型添加了额外的新创建的细粒度标签。我们最好的模型在识别受保护类别时的AUROC为0.96,在检测攻击类型时的AUROC为0.97。我们在https://github.com/harisbinzia/HatefulMemes上发布我们的代码

Racist or Sexist Meme? Classifying Memes beyond Hateful
Memes are the combinations of text and images that are often humorous in nature. But, that may not always be the case, and certain combinations of texts and images may depict hate, referred to as hateful memes. This work presents a multimodal pipeline that takes both visual and textual features from memes into account to (1) identify the protected category (e.g. race, sex etc.) that has been attacked; and (2) detect the type of attack (e.g. contempt, slurs etc.). Our pipeline uses state-of-the-art pre-trained visual and textual representations, followed by a simple logistic regression classifier. We employ our pipeline on the Hateful Memes Challenge dataset with additional newly created fine-grained labels for protected category and type of attack. Our best model achieves an AUROC of 0.96 for identifying the protected category, and 0.97 for detecting the type of attack. We release our code at https://github.com/harisbinzia/HatefulMemes
