将复数名词转换为单数

时间:2016-11-06 10:38:20

标签: java nlp nlg

这是使用SimpleNLG Java API

完成的

我想转换精灵"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));

2 个答案:

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)here(tutorial)以获取答案。
