Kleinberg's authority score

WebPURPOSE Calculates the hub and authority centrality scores of a valued network. DESCRIPTION Hubs and authorities are a natural generalization of eigenvector centrality. … WebOct 25, 2024 · The initial authority score for any page is the number of pages in the root set that link to that page. This is the most difficult portion of the test because it requires an extensive amount of data acquisition about the network and the links going to and from each of the “nodes” or sites.

WebKleinberg maintains, for each page p in the augmented set, a hub score, h(p) and an authority score, a(p). Each iteration consists of two steps: (1) replace each a(p) by the sum of the h(p) values of pages pointing to p; (2) replace each h(p) by the sum of the a(p) values of pages pointed to by p.

Unfortunately, Kleinberg [23] and others [3, 9] have observed that the authorities and hubs do not always match the original query due to “topic drift,” i.e., WebSource: Compiled from Kleinberg (1999) and León (2013). ...
