Page Rank [PR]

PR[Page Rank] is a link analysis fundamental that assigns a numerical weighting to each element of a href link set of doc., such as the www, with the purpose of "measuring" it is relative importance within the set. The fundamentals may be applied to any collection of record with reciprocal quotations and references. The number weight that it assigns to any given element e is also called the PageRank of e and denoted by PR(e).

PR was developed at Stanford University by Larry Page (hence the name Page-Rank) and later Sergey Brin as part of a project about a new kind of search engine. The project being started in 1995 and led to a functional prototype, named Google, in 1998. Shortly after, Page and Brin founded Google Inc., the company behind the Google search engine. While just one of many factors which determine the ranking of Google search reports, PR continues to provide the basis for all of Google's web search tools.
