java - 如何获取 Java WordNet 库中的类别

Question

我已经提取了每个单词的同义词集。现在我想获取每个同义词集的域或类别，这意味着例如，如果我有单词 light 我想获取 physicals 即同义词集的域.

现在假设我有同义词集 sense 这应该通过以下方式完成:

Pointer[] domain = sense.getPointers(PointerType.CATEGORY);

通过这样做，我总是得到 domain"empty 错误。我哪里错了？

此外，有没有办法获取表示域的字符串？

好吧，似乎没有人对此感兴趣，但我会发布我的工作解决方案。

 //'WordnetPOS' is an instance of the class POS defined in JWNL. It indicates the part of        
//speech tag. token
JWNL.initialize(new FileInputStream("path/file_properties.xml"));
Dictionary wordnet = Dictionary.getInstance();
IndexWord token = wordnet.lookupIndexWord(WordnetPos, word); //word is a string
Synset[] senses = token.getSenses();
String Dom = new String();

for (int i = 0; i < senses.length; i++) {
   String domSet = new String();
   try {

   //CATEGORY is the pointer type of the synset containing the domains

   Pointer[] pointerArr = senses[i].getPointers(PointerType.CATEGORY);
   for (Pointer pointer : pointerArr) {
       Synset syn = pointer.getTargetSynset();
       Word[] words = syn.getWords();
       for (Word word : words) {
           domaSet = domaSet + word.getLemma().trim().toLowerCase() + " ";
       }
   }
   catch (NullPointerException e) {
   }
   Dom = Dom + domSet;
}
