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.
