GetClosenessCentr

GetClosenessCentr(NId, Normalized=True, IsDir=False)

A graph method that returns closeness centrality of a given node NId. Closeness centrality is equal to 1/farness centrality.

Parameters:

• NId: int

  A node id in Graph.

• (optional) Normalized: bool

  Output should be normalized (True) or not (False).

• (optional) IsDir: bool

  Indicates whether the edges should be considered directed (True) or undirected (False).

Return value:

• float

  The closeness centrality of the node NId.

The following example shows how to get the closeness centrality for nodes in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 1000)
for NI in Graph.Nodes():
    CloseCentr = Graph.GetClosenessCentr(NI.GetId())
    print("node: %d centrality: %f" % (NI.GetId(), CloseCentr))

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 1000)
for NI in UGraph.Nodes():
    CloseCentr = UGraph.GetClosenessCentr(NI.GetId())
    print("node: %d centrality: %f" % (NI.GetId(), CloseCentr))

Network = snap.GenRndGnm(snap.TNEANet, 100, 1000)
for NI in Network.Nodes():
    CloseCentr = Network.GetClosenessCentr(NI.GetId())
    print("node: %d centrality: %f" % (NI.GetId(), CloseCentr))
