A summary for a collection of related documents can be generated by extracting phrases (100) from the documents which include common focus elements. Phrase intersection analysis (120) is then performed on the extracted phrases (100) to generate a phrase intersection table, where identical or equivalent phrases are identified. Temporal processing (140) on the phrases in the phrase intersection table is performed to remove ambiguous time references and to sort the phrases in a temporal sequence. Sentence generation is then used to combine the phrases in the phrase intersection table into a coherent summary.
L'invention concerne un résumé de plusieurs documents connexes, qui repose sur l'extraction, dans les documents, de phrases comprenant des éléments d'intérêt commun. On soumet lesdites phrases à une analyse d'intersection de phrase pour établir une table d'intersection de phrase, ce qui permet d'identifier les phrases identiques ou équivalentes. Le traitement temporel auquel on soumet ensuite les phrases dans cette table permet d'éliminer les références de temps ambiguës et de trier les phrases selon une séquence temporelle. Enfin, une fonction de génération de phrase permet de combiner les phrases de ladite table en un résumé cohérent.
