- Abstract summary: We propose a new multi-label multimodal task: detecting the type of propaganda techniques used in memes.
We 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.

- 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. 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.

We ran a task on detecting propaganda techniques in Arabic tweets as part of the WANLP 2022 workshop.
Subtask1 asks to identify the set of propaganda techniques used in a tweet, which is a multilabel classification problem.
Subtask2 asks to detect the propaganda techniques used in a tweet together with the exact span(s) of text in which each propaganda technique appears.

We describe our approach for the WANLP 2022 shared task which handles the task of propaganda detection in a multi-label setting.
The task demands the model to label the given text as having one or more types of propaganda techniques.
We show that an ensemble of five models performs the best on the task, scoring a micro-F1 score of 59.73%.

We offer a comprehensive survey with a focus on harmful memes.
One interesting finding is that many types of harmful memes are not really studied, e.g., such featuring self-harm and extremism.
Another observation is that memes can propagate globally through repackaging in different languages and that they can also be multilingual.

Our experiments demonstrate the usefulness of this approach, and identify difficulties and limitations in various configurations of sources and targets for the transfer step.
