Kleinberg's HITS Algorithm

Kleinberg's HITS (Hyperlink-Induced Topic Search) algorithm evaluates web pages based on their importance and relevance within a network. It assigns two scores to each page: "hub" scores, measuring how well a page points to valuable content, and "authority" scores, indicating the quality of the content a page receives links from. The algorithm iteratively updates these scores: good hubs point to many good authorities, and good authorities are linked by good hubs. Over time, it identifies key pages that serve as reliable sources (authorities) and helpful directories (hubs), effectively ranking pages according to their significance in the link structure.
