Super mediator – A new centrality measure of node importance for information diffusion over social network

We propose an efficient method to discover a new type of influential nodes in a social network, which we name “super-mediators”, i.e., those nodes which, if removed, decrease information spread. It is formulated mathematically as a problem of difference maximization of the average influence degree w...
