In addition to declarative sentences, SimpleNLG-DE can also generate six types of interrogative sentences:

  • Yes/No questions
  • How questions
  • Questions about the subject of a sentence (who or what)
  • Questions about the object of a sentence (who or what)

To generate interrogative sentences, simply proceed as you would with a declarative sentence, e.g.:

SPhraseSpec sentence = nlgFactory.createClause();
NPPhraseSpec subject = nlgFactory.createNounPhrase("Klaus");
sentence.setSubject(subject);
VPPhraseSpec verb = nlgFactory.createVerbPhrase("verlieren");
sentence.setVerb(verb);
NPPhraseSpec object = nlgFactory.createNounPhrase("das Spiel");
sentence.setObject(object);

String output = realiser.realiseSentence(sentence);

This code generates the sentence "Klaus verliert das Spiel.". By setting the INTERROGATIVE_TYPE of the sentence, it can be transformed into different interrogative sentences.

  • sentence.setFeature(Feature.INTERROGATIVE_TYPE, InterrogativeType.YES_NO); => Verliert Klaus das Spiel?
  • sentence.setFeature(Feature.INTERROGATIVE_TYPE, InterrogativeType.HOW);=> Wie verliert Klaus das Spiel?
  • sentence.setFeature(Feature.INTERROGATIVE_TYPE, InterrogativeType.WHO_SUBJECT); => Wer verliert das Spiel?
  • sentence.setFeature(Feature.INTERROGATIVE_TYPE, InterrogativeType.WHAT_OBJECT); => Was verliert Klaus?
