How semantic is Latent Semantic Analysis?
نویسنده
چکیده
Au cours des dix dernières années, l'analyse de la sémantique latente (LSA) a été utilisée dans de nombreuses approches TAL avec parfois de remarquables succès. Cependant, ses capacités à exprimer des ressemblances sémantiques n’ont pas été réellement recherchées de façon systématique. C’est l’objectif de ce travail, où la LSA est appliquée à un corpus de textes de langue courante (journal allemand). Les relations lexicales entre un mot et ses termes les plus proches sont analysés pour un test de vocabulaire. Ces résultats sont alors comparés avec les résultats obtenus lors d’une analyse des collocations.
