National audienceThis paper presents an exploratory analysis attempting to highlight patterns of col- laboration in social medias.

Results highlight that collaboration is generally performed in a small network while characterized by diversified topics.Nous présentons dans cet article une analyse exploratoire dans l’objectif d’identifier les patrons de...
