PageRank

  • : set of hyperlinked webpages
  • : webpages in P
  • : set of webpages pointing to u
  • : set of webpages that v points to
  • the PageRank is: (1.)
  • is chosen such that
  • is a vector over corresponding to a source of rank and is chosen such that
  • first term of function (1.) gives rank value based on initial rank
  • second term of (1.) gives rank value as a function of hyperlinks pointing at
