Topological Centrality in Social Network

The rich get richer phenomenon widely exists in social networks. There are two ways for a node in social network to become richer: linking to more nodes; and, linking to more important nodes. A node may get rise if it links to some important nodes than links to many but less important nodes. Both nodes and links play an important role in forming network centrality. Topological centrality is a network centrality measure that reflects relative centrality of nodes and links according to the influence between nodes, between links, and between node and link.
