How Google's PageRank Algorithm Works

Google's PageRank algorithm is one of the most important algorithms on the Internet. The algorithm attempts to rank pages according to their importance. But what does it mean for a web page to be "important"? In this video, we explore the "random surfer" model, which allows us to calculate

PageRank algorithm: how it works

The PageRank algorithm starts by giving an equal amount of PageRank to each node in the graph. Each node then shares its PageRank equally across all outgoing links. The value is interpolated with a uniform (initial) value of PageRank.

Web search 5: PageRank at convergence

It is difficult to predict the final PageRank values, but we can often guess which node will have a higher PageRank. Nodes with no in-links have a constant PageRank. Incoming links from nodes with a high PageRank value have a disproportionally large effect on the PageRank of a node.

Web search 3: introduction to PageRank

The PageRank algorithm treats hyperlinks as a voting mechanism: a link from page A to page B is a vote of confidence in B. The algorithm simulates a user following random hyperlinks on the web, and computes the proportion of time the user would spend on any given webpage.

Web search 1: more data = higher precision

A search engine has to deal with massive amounts of data. This is challenging computationally, but (surprisingly) makes it easier to get relevant documents to the top of a ranked list. Our argument is based on the observation that precision typically decreases with rank, and on the assumpt

Web search 6: PageRank using MapReduce

The PageRank algorithm has an elegant MapReduce implementation. The mapper emits initial PageRank values for every node. The reducer receives all PageRank contributions for a given node, adds them up, and emits its contribution to its own outgoing links.
