κ-Path Centrality


Definition

κ-path node centrality
For each node v of a graph G = (V,E), the κ-path node centrality Cκ(v) of v is defined as the sum, over all possible source nodes s, of the frequency with which a message originated from s goes through v, assuming that the message traversals are only along random simple paths of at most κ edges.
κ-Path Centrality
where s are all the possible source nodes, σκs(v) is the number of κ-paths originating from s and passing through v and σκs is the overall number of κ-paths originating from s.
