LinkRankCentrality

LinkRankCentrality[g,α]

gives the link-rank centralities for edges in the graph g and weight α.

LinkRankCentrality[g,α,β]

gives the link-rank centralities, using weight α and initial vertex page-rank centralities β.

LinkRankCentrality[{vw,…},…]

uses rules vw to specify the graph g.

Details and Options

  • Link-rank centralities represent the likelihood that a person randomly follows a particular link on the web graph.
  • Link rank is a way of measuring the importance of links between vertices.
  • The link-rank centrality of an edge is the page-rank centrality of its source vertex, divided by its out-degree.
  • If β is a scalar, it is taken to mean {β,β,…}.
  • LinkRankCentrality[g,α] is equivalent to LinkRankCentrality[g,α,1/VertexCount[g]].
  • Link-rank centralities are normalized.
  • The option WorkingPrecision->p can be used to control the precision used in internal computations.
  • LinkRankCentrality works with undirected graphs, directed graphs, multigraphs, and mixed graphs.
