simplenlg.framework.InflectedWordElement

This class defines the NLGElement that is used to represent an word that requires inflection by the morphology. It has convenience methods for retrieving the base form of the word (for example, kiss, eat) and for setting and retrieving the base word. The base word is a WordElement constructed by the lexicon.

    // hopefully will be better supported in later versions
  
    // get word element for "child"

    // create InflectedWordElement from word element
    InflectedWordElement inflectedWord = new InflectedWordElement(word);
    // set the inflected word to plural
    inflectedWord.setPlural(true);
    // realise the inflected word
    String result = realiser.realise(inflectedWord).getRealisation();
