29 Apr 2013 | | Abstract: | We study the Lobby-Hirsch index (h index for short) as a local node
centrality measure for complex networks. The h index is compared with degree (a
local measure), betweenness and Eigenvector centralities (two global measures)
in the case of a biological network (Yeast interaction protein-protein network)
and a linguistic network (Moby Thesaurus II). In both networks, the h index has
poor correlation with betweenness but correlates with degree and Eigenvector.
Being a local measure, one can take advantage by using the h index because it
carries more information about its neighbors when compared with degree
centrality, indeed it requires less time to compute when compared with
Eigenvector centrality. Results suggests that h index produces better results
than degree and Eigenvector measures for ranking purposes, becoming suitable as
a tool to perform this task. | | Source: | arXiv, 1304.7638 | | Services: | Forum | Review | PDF | Favorites | |
