comment générer les relations plus générales, moins générales et d'équivalence à partir de wordnet?relations wordnet
La similarité de wordnet dans RitaWordnet donne un nombre comme -1.0, 0.222 ou 1.0 mais comment arriver aux relations plus générales et moins générales entre les mots? quel outil serait idéal pour cela? s'il vous plaît aidez-moi
je reçois java.lang.NullPointerException, après imprime "les holonyms sont"

Vous pouvez essayer le JWI (le MIT Java Wordnet Interface). Il est facile à utiliser, afin d'obtenir les holonomys ou les hypernymes dont vous avez juste besoin pour l'itérer à l'aide d'un itérateur !! http://projects.csail.mit.edu/jwi/ –
