TL;DR
This paper introduces a new multimodal task for detecting propaganda techniques in memes, supported by a novel annotated dataset and experiments demonstrating the importance of combining text and image analysis.
Contribution
It presents the first dataset of 950 memes annotated with 22 propaganda techniques and evaluates multimodal models for this task, highlighting the necessity of integrating both modalities.
Findings
Multimodal models outperform unimodal ones in propaganda detection.
Understanding both text and image is crucial for accurate identification.
The dataset enables future research in multimodal propaganda analysis.
Abstract
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.

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…
