Recherche et visualisation de mots sémantiquement liés

Nous presentons PatternSim, une nouvelle mesure de similarite semantique qui repose d’une part sur des patrons lexico-syntaxiques appliques a de tres vastes corpus et d’autre part sur une formule de reordonnancement des candidats extraits. Le systeme, initialement developpe pour l’anglais, a ete adapte au francais. Nous rendons compte de cette adaptation, nous en proposons une evaluation et decrivons l’usage de ce nouveau modele dans la plateforme de consultation en ligne Serelex.
