PageRank
In information retrieval, PageRank is algorithm developed by Larry Page and Sergey Brin while at Sanford University.[1]
The value for the PageRank of an Internet page varies from 0 to 1 on a logarithmic scaleCite error: Invalid <ref> tag; invalid names, e.g. too many PageRank is based on links to an Internet page. The links are considered votes. According to Google:
- PageRank "considers the importance of each page that casts a vote, as votes from some pages are considered to have greater value, thus giving the linked page greater value"
An alternative is Kleinberg's Hyperlink-Induced Topic Search (HITS).[2][3]
History
Brin and Page published their article, "The anatomy of a large-scale hypertextual Web search engine", in 1998.[4] Their patent for PageRank was filed in 1998 and issued in 2001.Cite error: Invalid <ref> tag; invalid names, e.g. too many
PageRank is used by Google who owns its trademark which was filed and published in 2003.[5]
