The pages we extract links from are in fact Hubs using Kleinberg's terminology. To clarify the terminology, an Authority is a page that contains valuable information on a topic, and is linked to by many Hubs. A Hub is a page that links to many Authorities. So a pages Authority score (or Hub score) is defined in terms of hypertext linkage structure. The original document where Kleinberg introduces these concepts can be found at http://www.cs.cornell.edu/home/kleinber/auth.pdf (entitled Authoritative Sources in a Hyperlinked Environment).
