1. A method in a computing device for determining importance of documents with links between documents, the method comprising: generating transition probabilities of transitioning between pairs of source and target documents based on a determination of information available through each target document of a source document, each source document having one or more links to target documents of that source document, the transition probability for transitioning from a source document to a target document is based on the number of links on that target document and the total number of links on the target documents of that source document; storing the generated transition probabilities in a transition probability matrix; calculating importance of documents based on a stationary distribution of the generated transition probabilities stored in the transition probability matrix, the stationary distribution including stationary probabilities of visiting documents; and storing the calculated importance of the documents.

The method of claim 1 wherein transition probabilities are calculated according to the following: P ij ( N ) = d j ( N - 1 ) ⁢ 1 { ( i , j ) ∈ l ⁡ ( G ) } ∑ ( i , k ) ∈ l ⁡ ( G ) ⁢ d k ( N - 1 ) where P ij (N) represents the transition probability of transitioning from document i to document j based on a look-ahead distance of N−1 and d j (N−1) represents the count of links from document j that is a look-ahead distance of N−1 from document i.
