La polémique des « signaux faibles de radicalisation » dans Youtube, Facebook, Twitter et la presse en ligne : une analyse contrastive des corpus

On October 14, 2019, the security officer at the University of Cergy-Pontoise invited all staff to detect a series of “weak signals of radicalization” from students and teachers through a questionnaire. A few minutes later, a teacher from the same University posted a post of indignation on Twitter in response to this request. News bounces from one media to another. After a few hours, the controversy broke out on social networks. In this paper, I will show the different discursive modalities of the diffusion of this controversy in several social networks (“comments” space of Monde.fr, Twitter, Youtube, Facebook), starting from the typology of comments published (PAVEAU, 2017) and the discursive strategies used by users. I will show the interest of adopting a contrastive approach in the constitution and analysis of corpora (LONGHI, 2018) in order to have a more precise vision of how a controversy (AMOSSY, 2014), in a particular “moment discursif” (MOIRAND, 2007), is triggered and spreads in the web 2.0. In particular, this approach should bring out more specifically the specificities of the different social networks, not on the basis of pre-established criteria and classifications, but rather on the basis of the (techno) discursive materiality which occurs there.
