JWNL是用JAVA语言编写的用于读取WordNet词典库的组件库。
此次采用JWNL1.4-RC2，最高支持WordNet2.1(WINDOWS)，3.0(UNIX)。
1. 配置WordNet词典库。
配置文件位置：..\jwnl14-rc2\config\file_properties.xml中的<param name="dictionary_path" value="D:\Programs\WordNet\2.1\dict"/>
2. 在Main函数中使用JWNL加载
1 String propsFile = "..\jwnl14-rc2\config\file_properties.xml";
2 JWNL.initialize(new FileInputStream(propsFile));
3. 获得某一单词，如dog
1 IndexWord DOG = Dictionary.getInstance().getIndexWord(POS.NOUN, "dog");
4. 获得单词的直接上义词(Hypernym)
使用PointerUtils.getInstance().getDirectHypernyms(Synset synset)
1 this.demonstrateListOperation(DOG);
具体方法实现：
1 private void demonstrateListOperation(IndexWord word) throws JWNLException {
2 // Get all of the hypernyms (parents) of the first sense of <var>word</var>
3 PointerTargetNodeList hypernyms = PointerUtils.getInstance().getDirectHypernyms(word.getSense(1));
4 System.out.println("Direct hypernyms of \"" + word.getLemma() + "\":");
5 for(int idx = 0; idx < hypernyms.size(); idx++){
6 PointerTargetNode nn = (PointerTargetNode)hypernyms.get(idx);
7 for(int wrdIdx = 0; wrdIdx < nn.getSynset().getWordsSize(); wrdIdx++){
8 System.out.println("Syn" + idx + " of direct hypernyms of\"" + word.getLemma() + "\" : " +
9 nn.getSynset().getWord(wrdIdx).getLemma());
10 }
11 }
12 hypernyms.print();
13 }
5. 获得所有下义词树(Hyponym)，包含了其下义词的下义词
5.1 直接使用JWNL的方法打印出，单词DOG所有的下义词
1 this.demonstrateListOperation(ACCOMPLISH);
2
3
4 private void demonstrateTreeOperation(IndexWord word) throws JWNLException {
5 // Get all the hyponyms (children) of the first sense of <var>word</var>
6 PointerTargetTree hyponyms = PointerUtils.getInstance().getHyponymTree(word.getSense(1));
7 System.out.println("Hyponyms of \"" + word.getLemma() + "\":");
8 hyponyms.print();
9 }
5.2 通过循环获得单词的下义词来遍历DOG的所有下义词
1 BMTreeNode root = new BMTreeNode(DOG.getLemma());
2 demonstrateTreeOperation(DOG.getSense(1), root);
3 System.out.println(root.toString());
4
5
6 private void demonstrateTreeOperation(Synset word, BMTreeNode myTreeNode) throws JWNLException {
7 // Get all the hyponyms (children) of the first sense of <var>word</var>
8 PointerTargetNodeList hypernyms = PointerUtils.getInstance().getDirectHyponyms(word);
9 System.out.println("Direct hypernyms of \"" + getAllWordString(word.getWords()) + "\":");
10 for(int idx = 0; idx < hypernyms.size(); idx++){
11 PointerTargetNode nn = (PointerTargetNode)hypernyms.get(idx);
12 if (nn.getSynset().getWordsSize() > 0){
13 BMTreeNode child = new BMTreeNode(getAllWordString(nn.getSynset().getWords()));
14 myTreeNode.addChild(child);
15 this.demonstrateTreeOperation(nn.getSynset(), child);
16 }
17 }
18 }
5.3 将所有下义词添加到一个JTree控件中
1 HyponymsWindow win = new HyponymsWindow();
2 DefaultMutableTreeNode rootTreeNode = new DefaultMutableTreeNode(CAT.getLemma());
3 win.getDefaultTreeModel().setRoot(rootTreeNode);
4 demonstrateTreeOperation(CAT.getSense(1),win, rootTreeNode);
5 win.setVisible(true);
6
7
8 private void demonstrateTreeOperation(Synset word,HyponymsWindow win,DefaultMutableTreeNode parentTreeNode) throws JWNLException {
9 // Get all the hyponyms (children) of the first sense of <var>word</var>
10 PointerTargetNodeList hypernyms = PointerUtils.getInstance().getDirectHyponyms(word);
11 //System.out.println("Direct hypernyms of \"" + getAllWordString(word.getWords()) + "\":");
12 for (int idx = 0; idx < hypernyms.size(); idx++) {
13 PointerTargetNode nn = (PointerTargetNode) hypernyms.get(idx);
14 if (nn.getSynset().getWordsSize() > 0) {
15 String strWord = this.getAllWordString(nn.getSynset().getWords());
16 DefaultMutableTreeNode childTreeNode = new DefaultMutableTreeNode(strWord);
17 win.getDefaultTreeModel().insertNodeInto(childTreeNode, parentTreeNode, idx);
18 this.demonstrateTreeOperation(nn.getSynset(), win, childTreeNode);
19 }
20 }
21 }
