Hyperlink-Induced Topic Search (HITS; also known as hubs and authorities) is a link analysis algorithm that rates Web pages, developed by Jon Kleinberg. It was a precursor to PageRank.
The idea behind Hubs and Authorities stemmed from a particular insight
into the creation of web pages when the Internet was originally forming;
that is, certain web pages, known as hubs, served as large directories
that were not actually authoritative in the information that it held,
but were used as compilations of a broad catalog of information that led
users directly to other authoritative pages. In other words, a good hub
represented a page that pointed to many other pages, and a good
authority represented a page that was linked by many different hubs.
The scheme therefore assigns two scores for each page: its authority,
which estimates the value of the content of the page, and its hub
value, which estimates the value of its links to other pages.Continue Reading....
