Outils de représentation des réseaux sociaux
A social network is a social structure made up of a set of actors (such as individuals or organizations) and the dyadic ties between these actors (such as relationships, connections, or interactions). A social network perspective is employed to model the structure of a social group, how this structure influences other variables, or how structures change over time. [ 1 ] The study of these structures uses methods in social network analysis to identify influential nodes, local and global structures, and network dynamics.
