Brief Overview Of Google’s PageRank System?
PageRank is a family of algorithms that assigns a numerical value to pages on the Web in an effort PageRanks af the relevance or importance of that page. PageRank, which was developed by to Google founders Larry Page and Sergey Brin, is proprietary to Google, but there are other search engines that use a ranking system to help determine the order of search engine results. It’s interest- ing to note that PageRank is named for Larry Page and doesn’t refer to the rank of the page.
The exact algorithms that make up PageRank are not available to the general public. A version of the algorithms that you’ll find here was filed with the patent for PageRank, but only Google knows every variable that’s taken into account. It will help, however, if you understand how PageRank is calcu- lated, so the following example (from Wikipedia.org) should help clarify those calculations.
Simplified PageRank Algorithm
Assume a small universe of four web pages: A, B, C, and D. The initial approximation of PageRank would be evenly divided between these four documents. Hence, each document would begin with an estimated PageRank of 0.25.
