Community Structure of Complex Weighted Networks — •Sabine Tornow — Theoretische Physik III, Institut für Physik, Universität Augsburg, 86135 Augsburg, Germany

Complex networks arise in different contexts such as in biological systems (protein-protein interaction networks or in social systems, e.g., friendship networks. In addition to the complex topological structure these networks possess an intensity of their connection. It is therefore possible to assign a weight to each edge. One important property of many bio-molecular networks is the community structure which can be dependent on the network protein complexes, functional modules or coexpression clusters. We calculate the community structure of weighted bio-molecular networks with different methods including the superparamagnetic clustering and assess their results in the context of biological function.
