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: Webbest authorities and hubs for the query. The HITS score is query-speciﬁc in that it computes the authority scores of the pages after it compiles a subset of web pages. 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., how is ehv 1 spread

He presented examples that suggested the algorithm could help to filter out irrelevant or poor quality documents (i.e., they would have low authority scores) and identify high-quality documents (they would have high authority scores).

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.
