Algorithms
		• HyperSearch: use links to get text from related objects and enrich the text models • PageRank: use only ‘in links.’  use link matrix of entire web.  Weight links recursively based on objects with many ‘in links.’  google • Hyperlink induced text search (HITS): use both in and out links.  Recursively define ‘hubs’ (objects that point to many good authorities) and authorities (objects that have many hubs pointing to them).  Use portion of the web.
