摘要: Une approche classique en recherche d’information (RI) consiste a bâtir une representation des documents et requetes basee sur les mots simples constituant. L’utilisation de modeles bigrammes ete etudiee, mais contraintes l’ordre l’adjacence dans ces travaux ne sont pas toujours justifiees pour la d’information. Nous proposons nouvelle langue qui incorporent affinites lexicales (ALs), c’est dire paires non ordonnees se trouvent proches un texte. decrivons ce modele le comparons aux plus traditionnels unigrammes ainsi qu’au vectoriel.
