Pagerank Explained. Google's PageRank and how to make the most of it.

Pagerank Explained. Google's PageRank and how to make the most of it.: "Not long ago, there was just one well-known PageRank Explained paper, to which most interested people referred when trying to understand the way that PageRank works. In fact, I used it myself. But when I was writing the PageRank Calculator, I realized that the original paper was misleading in the way that the calculations were done. It uses its own form of PageRank, which the author calls 'mini-rank'. Mini-rank changes Google's PageRank equation for no apparent reason, making the results of the calculations very misleading.

Even though the author abandoned mini-rank as a result of this and another paper, the original, unchanged paper is still available on the web. So if you come across a PageRank Explained paper that uses 'mini-rank', it has been superceded and is best ignored."
