Coverting PointerTargetTree's to Strings

[Anonymous]

Im trying to analyse the hypernyms of nouns. when i use the print() method on a PointerTargetTree object i get all the hypernyms out putted to the screen. however when i try to convert the tree to a string using the toString() method all i get is the pointer id number, net.didion.jwnl.data.list.PointerTargetTreeNodeList@d26670.

all i need is the hypernym words, from the given word right up to the final hypernym 'entity' as strings in an array. any idea how i can do this.

many thanks,

john.

have u tried getting the root node and then iterating the parents/children and calling getWord() --> getLemma() for them?

can you please forward me a code fragment on how to do this ?

Thanks very much,

Would be possible to get the code for this? I have tried to modify the PointerUtils.makePointerTargetTreeList() function but I have been unable to make it work for Word only.

Thanks

private ArrayList getHypernym( PointerTargetTreeNodeList l, ArrayList p ) throws JWNLException {
  ArrayList parent = p;
  for (Iterator itr = l.iterator(); itr.hasNext();) {
    PointerTargetNode node = (PointerTargetNode) itr.next();
    Synset synset = node.getSynset();
    String name = synset.getWord(0).getLemma();
    parent.add(name);        
    PointerTargetNodeList targets = new PointerTargetNodeList(synset.getTargets(PointerType.HYPERNYM));
    if (targets.size() > 0) {
      parent = getHypernymTerm( targets, parent, name);
    }
  }
  return parent;
}
   
private ArrayList getHypernymTerm( PointerTargetNodeList l, ArrayList p, String s ) 
        throws JWNLException{
  ArrayList parent = p;
  if ( !s.equals("entity") ) {
    for (Iterator itr = l.iterator(); itr.hasNext();) {
      PointerTargetNode node = (PointerTargetNode) itr.next();
      Synset synset = node.getSynset();
      String term = synset.getWord(0).getLemma();
      parent.add(term);
      PointerTargetNodeList targets = new PointerTargetNodeList(synset.getTargets(PointerType.HYPERNYM) );
      if (targets.size() > 0) {
        parent = getHypernymTerm( targets, parent, term);
      }
    }
  }
  return parent;
}

I managed to get the code working for myself.

Cheers,
