  • "Il semble que le terme « masse critique » vienne d'une observation du trafic routier en Chine, où sans feux de signalisation aux croisements, les cyclistes attendent d'être assez nombreux, de faire masse pour s'engager et traverser ensemble. "
    Le principe de masse critique dans un réseau social correspond à un niveau d'activité à partir duquel le réseau change d'état de manière permanente. Par exemple, à partir d'un certain nombre de personne et d'un volume d'activité minimale d'interaction, un groupe de personne devient une communauté d'intérêt.
  • Community detection helps understanding the global structure of a network and the distribution of actors and activities.
    Moreover, the community structure influences the way information is shared and the way actors behave.
    Information spread quickly in a community and is shared by most of it members.
  • The centrality highlights the most important actors of the network and three definitions have been proposed by Freeman.
    The degree centrality considers nodes with the higher degrees (number of adjacent edges).
    The closeness centrality is based on the average length of the paths linking a node to others and reveals the capacity of a node to be reached.
    The betweenness centrality focuses on the capacity of a node to be an intermediary between any two other nodes. A network is highly dependent on actors with high betweenness centrality due to their position as intermediaries and brokers in information flow.
