Centrality indicators | Definition | Features | Applications |
|---|---|---|---|
Degree centrality | Total number of network lines connected to this actor | The study focuses on the value of an actor itself | To describe the degree of centrality of actors in a network |
Betweenness centrality | Two actors are indirectly connected through an actor, the number of shortcuts passing through the point as a percentage of the total number of shortcuts | This index measures the ability of actors to control and mediate the flow of resources and information in the network | To measure an actor’s control of resources in a network |
Closeness centrality | Sum of the reverse distances between an actor and other actors in the network | The larger the indicator, the closer the actor is to the center of the network, and the faster it can reach other points. It indicates the value of the actors in the network | To portray the value and position of actors in social networks |
