affichage hyponyms Résolu/Fermé

Question

Bonjour, Salut, J'entraine de faire un projet sur netbeans (java) avec wordnet, j'ai un problème avec ce code : private void demonstrateTreeOperation(IndexWord word) throws JWNLException { // Get all the hyponyms (children) of the first sense of word PointerTargetTree hyponyms = PointerUtils.getInstance().getHyponymTree(word.getSense(1)); System.out.println("Hyponyms of \"" + word.getLemma() + "\":"); hyponyms.print(); } Qu'il permet d'afficher l' hyponyms sur la console. SVP aide moi comment s'affiche l' hyponyms dans un fichier .txt, et est ce que si possible d'afficher graphiquement sous forme d'un arbre. Et MERCI d'avance.

Je ne suis pas sûr d'avoir compris tout ce que tu voulais faire, mais d'un point de vue "théorique" chaque nom ne devrait avoir qu'un seul hyponyme, donc récursivement tu n'obtiendras pas un arbre, mais une liste ! 
Si tu veux un arbre il va falloir considérer les hyperonymes du mot considéré. Je ne connais pas WordNet, j'ignore donc si cela est possible directement, ou s'il faut à chaque fois itérer tout le dictionnaire pour identifier les hyperonymies en considérant les mots qui ont pour hyponyme le mot recherché. Mais si le but est de faire un arbre complet d'hyperonymes (ou plus vraisemblablement une forêt) il va falloir un bon algorithme pour ne pas faire exploser la combinatoire...La confiance n'exclut pas le contrôle

ce code affiche ça (à l'aide de la méthode hyponyms.print(); ) dans la console :

Hyponyms of "car":



[PointerTargetTreeNode: [Synset: [Offset: 2853224] [POS: noun] Words: car, auto, automobile, machine, motorcar -- (4-wheeled motor vehicle; usually propelled by an internal combustion engine; "he needs a car to get to work")] null [Has Parent? true] [Has Children? true] [Has Pointers? false]]
  [PointerTargetTreeNode: [Synset: [Offset: 2608716] [POS: noun] Words: ambulance -- (a vehicle that takes people to and from hospitals)] [PointerType: [Label: hyponym] [Key: ~] Applies To: noun, verb] [Has Parent? true] [Has Children? true] [Has Pointers? false]]
    [PointerTargetTreeNode: [Synset: [Offset: 3279543] [POS: noun] Words: funny_wagon -- (an ambulance used to transport patients to a mental hospital)] [PointerType: [Label: hyponym] [Key: ~] Applies To: noun, verb] [Has Parent? false] [Has Children? false] [Has Pointers? false]]
  [PointerTargetTreeNode: [Synset: [Offset: 2715796] [POS: noun] Words: beach_wagon, station_wagon, wagon, beach_waggon, station_waggon, waggon -- (a car that has a long body and rear door with space behind rear seat)] [PointerType: [Label: hyponym] [Key: ~] Applies To: noun, verb] [Has Parent? true] [Has Children? true] [Has Pointers? false]]
    [PointerTargetTreeNode: [Synset: [Offset: 4041413] [POS: noun] Words: shooting_brake, estate_car -- (another name for a station wagon)] [PointerType: [Label: hyponym] [Key: ~] Applies To: noun, verb] [Has Parent? false] [Has Children? false] [Has Pointers? false]]

  [PointerTargetTreeNode: [Synset: [Offset: 2826514] [POS: noun] Words: cab, hack, taxi, taxicab -- (a car driven by a person whose job is to take passengers where they want to go in exchange for money)] [PointerType: [Label: hyponym] [Key: ~] Applies To: noun, verb] [Has Parent? true] [Has Children? true] [Has Pointers? false]]

....

et wordnet affiche comme ça :


2 of 5 senses of car                                                    

Sense 1
car, auto, automobile, machine, motorcar -- (4-wheeled motor vehicle; usually propelled by an internal combustion engine; "he needs a car to get to work")
       => ambulance -- (a vehicle that takes people to and from hospitals)
           => funny wagon -- (an ambulance used to transport patients to a mental hospital)
       => beach wagon, station wagon, wagon, beach waggon, station waggon, waggon -- (a car that has a long body and rear door with space behind rear seat)
           => shooting brake, estate car -- (another name for a station wagon)
       => bus, jalopy, heap -- (a car that is old and unreliable; "the fenders had fallen off that old bus")
       => cab, hack, taxi, taxicab -- (a car driven by a person whose job is to take passengers where they want to go in exchange for money)
           => gypsy cab -- (a taxicab that cruises for customers although it is licensed only to respond to calls)
           => minicab -- (a minicar used as a taxicab)
....

mais comment l'affiche dans un fichier .txt par exemple ?

Il faut te référer à la documentation, ce qui va dépendre de quelle implémentation tu utilises. Le site de WordNet référence 9 implémentations Java (cf. liste).

Vu que dans ton code tu as une JWNLException, je vais considérer que tu utilises extJWNL dont la documentation est ici, même si tu utilises des méthodes qui n'y sont pas référencés (IndexWord.getSense(int) par exemple).

Pour enregistrer les résultats dans un fichier il ne faudra pas utiliser la méthode print de PointerTargetTree, mais une de ses autres méthodes (il faudra que tu cherches précisément laquelle) qui te renverras une liste, voici un exemple(je ne l'ai pas testé)

private void demonstrateTreeOperation(IndexWord word, File file)
{
    FileOutputStream out = new FileOutputStream(file);
    out.write(("Hyponyms of \"" + word.getLemma() + "\":").getBytes());

    for (Synset synset : word.getSenses()) // Pour chaque sens du mot
    for (PointerTargetNodeList node : PointerUtils.getInstance().getHyponymTree(synset).toList()) // Pour chaque noeud de l'arbre
        node.print(out); // Imprimer le résultat dans le fichier

    out.close();
}
