这是使用SimpleNLG Java API
完成的我想转换精灵＆＃34;对精灵。下面的代码从单数转换为复数，如何修改为从复数转换为单数？
final XMLLexicon xmlLexicon = new XMLLexicon();
final WordElement word = xmlLexicon.getWord("elves", LexicalCategory.NOUN);
final InflectedWordElement pluralWord = new InflectedWordElement(word);
pluralWord.setPlural(true);
final Realiser realiser = new Realiser(xmlLexicon);
System.out.println(realiser.realise(pluralWord));
答案 0 :(得分：1)
在这个API中显然没有setSingular()方法（我真的很依赖那个方法，而且我觉得它有点像这样的东西没什么好笑的。）另外从V4开始，没有setPlural()方法。
[1]请注意，在SimpleNLG V4中，没有词典方法 直接得到一个单词的变形变体;换句话说，没有 相当于SimpleNLG V3的V4中的getPlural（），getPastParticiple（）， 等方法。在V4中可以计算变形的变体 单词，但过程更复杂：基本上我们需要 在基本表单周围创建一个InflectedWordElement，添加适当的 这个InflectedWordElement的功能，然后实现它。
我认为这可能会成功:(我没有测试它，因为我现在没有时间。）
final XMLLexicon xmlLexicon = new XMLLexicon();
final WordElement word = xmlLexicon.getWord("elves", LexicalCategory.NOUN);
final InflectedWordElement singularWord = new InflectedWordElement(word);
WordElement sw = singularWord.getBaseWord();
final Realiser realiser = new Realiser(xmlLexicon);
System.out.println(realiser.realise(sw));
如果这不起作用，欢迎您或其他任何人查看here(docs)和here(tutorial)以获取答案。
