Table 1 Indicators used in the study to identify the most important actors
Indicator type | Indicator | Definition |
|---|---|---|
Macro indicators | node | The basic unit and constituent of a network (actors) [36] |
Edges | Lines that connect two nodes, in which the links may have weight (importance, distance, etc.) in a network [36] | |
density | This index is defined as the ratio of the number of all available links to all possible links [31] | |
Micro indicators | Degree centrality | The number of links that connect a particular node to other nodes. [31] |
Weighted degree centrality | When the links between the actors have weight, this index is obtained by multiplying the weight by the number of links that enter or exit a node [31] | |
Closeness centrality | The sum of geodetic paths between a node and any other node in the network [31] | |
Betweenness centrality | There are a number of other vertices that must pass through a particular node to reach their shortest [37] | |
Page rank | The page rank index is calculated based on the relationship of each node in its weighted activity diagram and its measurement is calculated recursively [38] | |
Clustering Coefficient | This indicator shows how the nodes are located next to their neighboring nodes [39] |
