Propagandist messages are conveyed through a number of rethorical and psychological techniques.
We are currently organising a shared task at SemEval 2020. After the task is over, we will keep a live leaderboard for the users to compare the performances of their systems and to keep track of the state of the art.
Proppy is a system that organizes news articles into events and, for each event, shows articles according to their level of propagandistic content. We aim at raising awareness into individual readers as well as providing tools for organizations to monitor large amounts of news articles.
Among all persuasion techniques defined in the literature, we have selected the ones that can be found in news articles and the ones that can be spotted intrinsically, i.e., just by reading the article, without resorting to external knowledge. The final list consists of 18 techniques.
Currently, we have annotated 500 articles in collaboration with A Data Pro. The annotation process is described here and in Publication 3 below. The articles publicly available at the moment can be found here.
