The increasing popularity of electronic messages challenges social science researchers, particularly regarding data representativeness and quality. We propose and evaluate a methodology to create a corpus of Twitter data for a given population by sampling the targeted user population. In our case, the population is the groups of citizens, media and politicians using Twitter in Belgium (French and Dutch languages), Norway and France. We present in particular a machine-learning based methodology that enables the population sampling. We also present a methodology to evaluate the representativeness of our corpus compared to the Full Twitter stream of the targeted population. https://osf.io/gse4k/

The management of the health crisis we are facing far exceeds the management of the coronavirus outbreak. Containment measures taken in response to the epidemic have very wide medical and societal impacts. In parallel with the epidemic, there is also an 'infodemic', a huge and continuous flow of true and false information that is difficult to manage for individuals. Doctors, and university doctors in particular, find themselves in a media space of which they are not customary. As part of an academic effort to draw the attention of the government and experts to the importance of social sciences and humanities in emerging from the crisis, a neurologist joined media sociology specialists and a psychologist expert on anxiety disorders to better understand the impact of sources of (mis-) information on the behaviour of the population, with a particular focus on the differences between the general public and health professionals. ; La gestion de la crise sanitaire à laquelle nous sommes confrontés dépasse largement la gestion de l'épidémie de coronavirus. Les mesures de confinement prises en réponse à l'épidémie ont des impacts médicaux et sociétaux très larges. Parallèlement à l'épidémie évolue également une « infodémie », un flux énorme et incessant d'informations, vraies et fausses, difficiles à gérer pour les individus. Les médecins, et les médecins universitaires en particulier, se retrouvent dans un espace médiatique dont ils sont peu coutumiers. Dans le cadre d'un effort académique pour attirer l'attention du gouvernement et des experts sur l'importance des sciences sociales et humaines pour sortir de la crise, un neurologue s'est associé à des spécialistes de la sociologie des médias et à un psychologue expert des troubles anxieux pour mieux comprendre l'impact des sources de (més-) informations sur le comportement de la population, avec un accent particulier sur les différences existant entre le grand public et les professionnels de la santé.
