Ranking-Betweenness Centrality
Definition
This centrality measure combines the idea behind the random-walk betweenness centrality measure
and the idea of ranking the nodes of a network produced by an adapted PageRank algorithm.
In some types of networks, as for example street networks, a node does not measure its importance only by its connectivity to other nodes; there are other factors that can and should be measured to be considered a true ranking of importance within the network.
The PageRank algorithm modified with the primary objective to introduce a data matrix representing some type of information of the network itself. This information allows us to obtain a ranking of the nodes of the network which is used in the random-walk betweenness algorithm. This centrality measure reduces the effect of the randomness present in the random-walk betweenness measure and takes into account, in a decisive way, the information we want to evaluate of the network.
The detailed example is presented at [AGRYZKOV, T., 2014].
