摘要:

宣传可以被定义为一种旨在影响人们的意见或行动以实现特定目标的传播形式;这是通过定义明确的修辞和心理手段来实现的。我们今天所知的宣传形式可以追溯到17世纪初。然而,随着互联网和社交媒体的出现,它开始以比以前更大的规模传播,从而成为主要的社会和政治问题。如今,社交媒体中的大部分宣传都是多模态的,混合了文本和视觉内容。考虑到这一点,在这里,我们提出了一个新的多标签多模态任务:检测类型的宣传技术中使用的模因。我们进一步创建并发布了一个包含950个模因的新语料库,并仔细注释了22种宣传技巧,它们可以出现在文本中,图像中,或者两者兼而有之。我们对语料库的分析表明,理解这两种方式是必不可少的检测这些技术。这一点在我们的实验中得到了进一步证实,我们使用了几种最先进的多模态模型。

英文摘要:

Propaganda can be defined as a form of communication that aims to influence the opinions or the actions of people towards a specific goal; this is achieved by means of well-defined rhetorical and psychological devices. Propaganda, in the form we know it today, can be dated back to the beginning of the 17th century. However, it is with the advent of the Internet and the social media that it has started to spread on a much larger scale than before, thus becoming major societal and political issue. Nowadays, a large fraction of propaganda in social media is multimodal, mixing textual with visual content. With this in mind, here we propose a new multi-label multimodal task: detecting the type of propaganda techniques used in memes. We further create and release a new corpus of 950 memes, carefully annotated with 22 propaganda techniques, which can appear in the text, in the image, or in both. Our analysis of the corpus shows that understanding both modalities together is essential for detecting these techniques. This is further confirmed in our experiments with several state-of-the-art multimodal models.
