Evaluation Method of Node Centrality in Complex Directed Network

摘要

According to the research on node centrality of complex network, the existing methods although take the global and local importance of node into account, but don't consider the importance of adjacent edges and the direction of interaction. For this, provides a new method for measuring the node centrality of complex directed network, considers the node's role in network efficiency and degree distribution and the importance of adjacent edges to make the evaluation of node centrality more precisely. An illustrative example proves that the method is reasonable and valid.
