I'm using SimpleNLG 4.4.2 to get plural form for a noun:
final XMLLexicon xmlLexicon = new XMLLexicon();
final WordElement word = xmlLexicon.getWord("apple", LexicalCategory.NOUN);
System.out.println(word);
System.out.println(word.getFeature(LexicalFeature.PLURAL));
However even for this simple example, getFeature returns null instead of apples. What am I doing wrong?
