La plateformisation des médias français et le ton du débat public

The authors seek to understand where and when YouTube comment sections are hit by brutal or aggressive debates and the factors that limit or foster this aggressive behaviour. To do so, they use a device at the crossroads of automated language processing and the political economy of media. The study is based on 2,209,206 comments, 1,184,859 of which are found in discussion threads, from the comment sections of 46,090 videos. The videos are taken from the YouTube channels of 57 different French media channels representing a variety of positions and institutional categories.
