Community identification has been a hot spot and a cutting-edge topic among researchers.Since none of the present community identification methods simultaneously meets the requirements
such as lower time complexity
independence of expertise or experiences
allowance for overlapping nodes and so on
an overlapping community identification method is proposed based on topological potential theory.This method can also identify the structural holes in communities at the same time by the presented uncertainty measure of the community identity of the overlapping nodes
and its effectiveness is verified by experiments.In addition
an influence factor optimization algorithm is proposed and network fragility is discussed and prooved from the perspective of structural hole theory.
