Link Analysis (Link Analysis)

Description

Unlike "flat" document collections, the World Wide Web is hypertext and provides considerable auxiliary information on top of the text of the web pages, such as link structure and link text. With link analysis, we take advantage of the link structure of the Web to produce a global "importance" ranking of every web page that helps search engines and users quickly make sense of the vast heterogeneity of the World Wide Web.
