This study focuses on students' perceptions of a quasi-unprecedented classroom situation during the Covid-19 pandemic. At the time of the research, conducted in a French high school in the United States between November 2020 and April 2021, the CM2 class (last year of elementary school in the French system) of a teacher, Marion, included 21 students. Among them, 19 attended face-to-face classes while two were kept at home by their parents to attend school remotely with self-study work (with Google Classroom) and synchronous class time (through videoconferencing). This co-modal situation became widespread during the pandemic and could occur again in the future. Comodality is one of the focal points of the "Français Plus" research project. Based on drawings and interviews with children, our study examines the object of students' attention in a situation where knowledge is strongly mediated by technology.

Text visualization is the technique of using graphs and charts to examine text as data. Often, these do not represent a text directly and instead display an output based on word counts, word sequences, and so on. This technique can provide insights into important keywords in a text, provide an overview of textual content, or reveal trends and patterns within one text or across many texts. This paper describes recent development of and experiments with several tools for the Grub Street Project to generate visualizations of eighteenth-century texts, especially in terms of the spatial relationships of words and entities on the pages of the original documents. Two examples are discussed in this article as test cases: Edward Ward's The London Spy Compleat, in Eighteen Parts (1703) and Alexander Pope's The Dunciad. With Notes Variorum (1729).

During the first wave of COVID‑19, the uncertainty about a prospect vaccine combined with the constant media bombardment have fueled the fear of strict periods of confinement measures, creating a fertile ground for fake news and misleading social media debates. This paper studies how the public attention to certain pandemic-related topics and the social media activity of health and policymaker influencers impact the energy sector. Our findings suggest that during periods of growing attention to the term “Coronavirus”, social media activity of policymaker influencers exhibits a negative relationship with the energy sector. However, given the positive and scientific connotation, when the public attention to the term “Vaccine” increases, we observe a positive impact of international health organizations.

La désambiguïsation sémantique permet de lever des ambiguïtés dans le but d'apporter des informations supplémentaires de façon à orienter le choix d'une signification parmi celles possibles. Si par nature elle est surtout utilisée en linguistique, son champ d'action ne s'y limite pas: certaines techniques de désambiguïsation peuvent aussi être utiles dans d'autres domaines tels que la médecine (diagnostic) et l'informatique (recherche documentaire; e.g. Google, Wikipédia) pour ne citer que ceux-là. Ce mémoire propose l'étude et la comparaison de trois modèles de désambiguïsation supervisés, basées sur les chaînes de Markov à états cachés et plus généralement sur les réseaux bayésiens dynamiques.La comparaison de ces outils sur plusieurs fichiers textes suggère la supériorité des réseaux bayésiens dynamiques généraux sur les chaînes de Markov.
