Abstract:
Populism is a phenomenon that is noticeably present in the political landscape of various countries over the past decades. While populism expressed by politicians has been thoroughly examined in the literature, populism expressed by citizens is still underresearched, especially when it comes to its automated detection in text. This presentation gives an overview of the existing definitions of populism in the literature and based on this presents an annotation study that resulted in the first annotated corpus of news comments for populism in the German language. It features 1,200 comments collected between 2019-2021 that are annotated for populist motives anti-elitism, people-centrism and people-sovereignty. This study showed that annotators reach a high agreement when labeling news comments for these motives. The data set is collected to serve as the basis for a large-scale case study using machine-learning methods. Hereby the model was applied to a corpus of news comments from Austrian daily newspaper Der Standard to investigate the connection between COVID-19 and populist user comments.
Presentation at the ÖTSI workshop of the 47. Austrian linguistic conference with a contribution to the topic of natural language processing, specifically populism detection using machine learning models.
