3. A computing device for calculating importance of web pages with hyperlinks to other web pages, a source web page including one or more hyperlinks to target web pages, comprising: a component that generates transition probabilities of transitioning between pairs of web pages, the transition probabilities of transitioning from a source web page to its target web pages being based on relative amount of information content available through the hyperlinks of the source web page to the target web pages; a component that calculates importance of the web pages based on a stationary distribution of the generated transition probabilities, the stationary distribution include a stationary probability of visiting each web page; and a component that ranks web pages based on the calculated importance.
