Table 2 Definition of network parameter
Parameter | Description |
|---|---|
Hub score | Kleinberg's hub. |
Path length | The length of a path. |
Shortest path | The shortest path between two vertices. |
Constraint | Calculates Burt's constraint for each vertex. |
Degree | The number of edges connected to a vertex. |
Grith | The length of the shortest circle in the graph. |
Modularity | Modularity of a community structure of a graph. |
Graph motifs | The small subgraphs with a well-defined structure. |
Articulation point | A vertex that, if removed, will disconnect the graph. |
Node betweenness | The number of shortest paths that pass through a vertex. |
Edge betweenness | The number of shortest paths that pass through an edge. |
Diameter | The diameter of a graph is the length of the longest geodesic. |
Cocitation coupling | Two vertices are cocited if there is another vertex citing both of them. |
Transitivity | Measures the probability that the adjacent vertices of a vertex are connected. |
Bibliographic coupling | The bibliographic coupling of two vertices is the number of other vertices they both cite. |
Closeness centrality | Measures how many steps are required to access every other vertex from a given vertex. |
Coreness | The coreness of a vertex is k if it belongs to the k-core but not to the (k+1)-core, a subgraph where every node has k connections. |
Graph density | The density of a graph is the ratio of the number of edges and the number of possible edges. |
