A method and system for propagating the relevance of labeled documents to a query to unlabeled documents is provided. The propagation system provides training data that includes queries, documents labeled with their relevance to the queries, and unlabeled documents. The propagation system then calculates the similarity between pairs of documents in the training data. The propagation system then propagates the relevance of the labeled documents to similar, but unlabeled, documents. The propagation system may iteratively propagate labels of the documents until the labels converge on a solution. The training data with the propagated relevances can then be used to train a ranking function.

L'invention concerne un procédé et un système permettant de propager la pertinence de documents référencés vers une requête à des documents sans référence. Le système de propagation fournit des données d'apprentissage qui comportent des requêtes, des documents référencés avec leur pertinence par rapport aux requêtes, et des documents sans référence. Le système de propagation calcule ensuite la similitude entre des paires de documents dans les données d'apprentissage. Il propage alors la pertinence des documents référencés vers des documents similaires mais sans référence. Le système de propagation peut d'une manière itérative propager des références des documents jusqu'à e que lesdites étiquettes convergent sur une solution. Les données d'apprentissage avec les pertinences propagées peuvent ensuite être utilisées pour former une fonction de classement.
