Density-based shrinkage for revealing hierarchical and overlapping community structure in networks

Huang, Jianbin; Sun, Heli; Han, Jiawei; Feng, Boqin - In: Physica A: Statistical Mechanics and its Applications 390 (2011) 11, pp. 2160-2171

The investigation of community structure in networks is an important issue in many disciplines, which still remains a challenging task. First, complex networks often show a hierarchical structure with communities embedded within other communities. Moreover, communities in the network may overlap...
