Discovering community membership in biological networks with node topology potential

In this paper, a novel approach is proposed to discover community membership in complex networks with node topology potential, along with the experiment on complex biological networks. The concept of physical field is brought into networks. Nodes will have a certain topology potential since they can affect and be affected by the others nearby. And this topology potential is an index to measure the interaction among nodes. Based on the distributing feature of node topology potential, the community memberships are uncovered. A biological network is finally experimented to show the effectiveness of the proposed algorithm.
