Table 2 The descriptions of SNA metrics
From: An integrated approach for knowledge extraction and analysis in collaborative knowledge construction
SNA metrics | Description |
|---|---|
Density | The ratio of actual links between any nodes to all potential possible links |
Average Path Length (APL) | The average number of the shortest paths for all possible pairs of nodes |
Transitivity | The ratio of transitive triads to all triads in a network |
Reciprocity | The ratio of symmetric dyads to non-null dyads in a network |
Centralization | The extent to which degree centrality is concentrated in a network ranged between 0 and 1 |
Distance | The maximum value of the distance between any two nodes in the network |
Average Degree (AD) | The mean of all nodes’ degrees |
Average Weighting Degree (AWD) | The mean of all nodes’ weighted degree |
