salsa: Find the SALSA as 'hub' or 'authority' score

Description

The Stochastic Approach for Link-Structure Analysis (SALSA) is combination of HITS and PageRank which creates a neighborhood graph using authority and hub pages and links and create a bipartite graph of the authority and hub pages in the neighborhood graph.

Usage

salsa(graph, vids = V(graph), score = c("hub", "authority"))

Arguments

graph

The input graph as igraph object

vids

Vertex sequence, the vertices for which the centrality values are returned. Default is all vertices.

score

Character constant, gives which score should be calculated and must be one of 'hub' or 'authority'. The default is 'hub'.

Value

A numeric vector contaning the centrality scores for the selected vertices.
