Kleinberg's authority score

WebJon Kleinberg's algorithm called HITS identifies good authorities and hubs for a topic by assigning two numbers to a page: an authority and a hub weight. These weights are … WebKleinberg in 1998 to rate Web pages. A precursor to PageRank, HITS is a search query dependent algorithm ... According to (1) the Authority score of a page is the sum of all the Hub scores of pages that point to it [8]. Hub Update Rule: ∀p, we update hub (p) as follows:

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.

The HITS score is query-specific in that it computes the authority scores of the pages after it compiles a subset of web pages.
