RadialityCentrality

RadialityCentrality[g]

gives a list of radiality centralities for the vertices in the graph g.

RadialityCentrality[g,"In"]

gives a list of in-centralities for a directed graph g.

RadialityCentrality[g,"Out"]

gives a list of out-centralities for a directed graph g.

RadialityCentrality[{vw,},]

uses rules vw to specify the graph g.

Details

  • Radiality in-centralities are also known as integration centralities.
  • RadialityCentrality will give high centralities to vertices that are a short distance to every other vertex in its reachable neighborhood compared to its diameter.
  • Radiality out-centrality for a vertex is computed using the out component for the vertex and is given by , where is the distance from to in , is the diameter of , and the sum is over the vertices in .
  • Radiality in-centrality for a vertex is computed using the in component for the vertex and is given by , where is the distance from to in , is the diameter of , and the sum is over the vertices in .
  • The radiality centrality for an isolated vertex is taken to be zero.
  • RadialityCentrality works with undirected graphs, directed graphs, weighted graphs, multigraphs, and mixed graphs.
