Detailed Description

A quality measure that measures the dominance of hubs in clusters.

The hub dominance of a single cluster is defined as the maximum cluster-internal degree of a node in that cluster divided by the maximum cluster-internal degree, i.e. the number of nodes in the cluster minus one. The value for all clusters is defined as the average of all clusters. Strictly speaking this is not a quality measure as this is rather dependent on the type of the considered graph, for more information see Lancichinetti A, Kivelä M, Saramäki J, Fortunato S (2010) Characterizing the Community Structure of Complex Networks PLoS ONE 5(8): e11976. doi: 10.1371/journal.pone.0011976

Member Function Documentation

virtual bool NetworKit::PartitionHubDominance::isParallel ( ) const
false - this implementation is not paralle.

Reimplemented from NetworKit::Algorithm.

virtual bool NetworKit::PartitionHubDominance::isSmallBetter ( ) const
false - small values are not better, large values indicate better cluster cohesion.

Implements NetworKit::LocalCommunityEvaluation.

void NetworKit::PartitionHubDominance::run ( )

Execute the algorithm.

Implements NetworKit::Algorithm.
