The webgraph describes the directed links between pages of the World Wide Web. A graph, in general, consists of several vertices, some pairs connected by edges. In a directed graph, edges are directed lines or arcs. The webgraph is a directed graph, whose vertices correspond to the pages of the WWW, and a directed edge connects page X to page Y if there exists a hyperlink on page X, referring to page Y.



  • The webgraph is used for computing the PageRank [5] of the WWW pages.
  • The webgraph is used for computing the personalized PageRank.[6]
  • The webgraph can be used for detecting webpages of similar topics, through graph-theoretical properties only, like co-citation [7]
  • The webgraph is applied in the HITS algorithm for identifying hubs and authorities in the web.
