A method and system is provided for calculating importance of documents based on transition probabilities from a source document to a target document based on looking ahead to information content of target documents of the source document. A look-ahead importance system generates transition probabilities of transitioning between any pair of source and target documents based on analysis of links to target documents of the source document. The system may calculate the transition probabilities based on the number of links on documents a look-ahead distance away. The system then solves for the stationary probabilities of the transition probabilities. The stationary probabilities represent the importance of the documents.
Le procédé et le système calculent l'importance de documents en fonction des probabilités de passage d'un document source à un document cible. Pour cela, ils anticipent le contenu informationnel des documents cibles du document source. Un système d'importance anticipée génère les probabilités de passage entre n'importe quelle paire de documents source et cible grâce à l'analyse des liens menant vers les documents cibles du document source. Le système peut calculer les probabilités de passage en fonction du nombre de liens sur les documents anticipés, puis il détermine les probabilités fixes correspondant aux probabilités de passage et représentant l'importance des documents.
