Searching WordNet for Synonym gives only one result

Question

I am using java jwi API for searching the wordnet to get the synonyms of a word. The problem is that it only gives me one result the word to find its synonyms itself. Please guide me. Is it possible to get the list of all possible synonyms of a given word? My code is:

  public void searcher() {
    try {

        url = new URL("file", null, path);


        dict = new Dictionary(url);
        try {
            dict.open();
        } catch (IOException ex) {
            JOptionPane.showMessageDialog(null, "Dictionary directory does not exist\n" + ex + "\nClass:Meaning Thread", "Dictionary Not Found Error", JOptionPane.ERROR_MESSAGE);

        }

        IIndexWord idxWord = dict.getIndexWord("capacity", POS.NOUN);
        IWordID wordID = idxWord.getWordIDs().get(0);
        IWord word = dict.getWord(wordID);


        //Adding Related Words to List of Realted Words
        ISynset synset = word.getSynset();
        for (IWord w : synset.getWords()) {
            System.out.println(w.getLemma());
        }


    } catch (Exception e) {
    }

}

The output is only:

capacity

itself! The actual synonyms must be:

  capability
  capacitance 
  content
  electrical capacitance
  mental ability...(so on)

So is there anything I missed in the code or can somebodygive me any ideas what is the real problem?

Thanks in advance

Answer 1

So, here comes the answer i use Java JAWS for wordnet searching! The steps are:

    1- Download WordNet Dictionary from 

Here

    2- Install WordNet
    3- Go to Installed Directory and copied the WordNet Directory (in my case C:\Program Files (x86) was the Directory for WordNet Folder)
    4- Pasted it into my Java Project (under MyProject>WordNet)
    5- Making Path to the directory as:
       File f=new File("WordNet\\2.1\\dict");
       System.setProperty("wordnet.database.dir", f.toString());
    6- Got Synonyms as:

       public class TestJAWS{
              public static void main(String[] args){
                    String wordForm = "capacity";
                    //  Get the synsets containing the word form=capicity

                   File f=new File("WordNet\\2.1\\dict");
                   System.setProperty("wordnet.database.dir", f.toString());
                   //setting path for the WordNet Directory

                   WordNetDatabase database = WordNetDatabase.getFileInstance();
                   Synset[] synsets = database.getSynsets(wordForm);
                   //  Display the word forms and definitions for synsets retrieved

                   if (synsets.length > 0){
                      ArrayList<String> al = new ArrayList<String>();
                      // add elements to al, including duplicates
                      HashSet hs = new HashSet();
                      for (int i = 0; i < synsets.length; i++){
                         String[] wordForms = synsets[i].getWordForms();
                           for (int j = 0; j < wordForms.length; j++)
                           {
                             al.add(wordForms[j]);
                           }


                      //removing duplicates
                       hs.addAll(al);
                       al.clear();
                       al.addAll(hs);

                      //showing all synsets
                      for (int i = 0; i < al.size(); i++) {
                            System.out.println(al.get(i));
                      }
                   }
              }
              }
              else
              {
               System.err.println("No synsets exist that contain the word form '" + wordForm + "'");
              }
       } 

The Thing is you must have jaws-bin.jar
