Abstract: Identifying central nodes in a network is crucial to accelerate or contain the spreading of information such as diseases and rumors. The problem is formulated as follows, given a complex network, which node(s) is (are) the more important ? The idea of centrality was initially introduced in the context of sociology, to look whether there is a relation between the location of an individual in the network and its influence in group processes. Since then, a plethora of centrality measures has emerged over the years and were employed in a multitude of contexts to rank nodes according to their topological importance. Each centrality targets the problem of influence from its own perspective.
