This difficulty in generation, however, does not mean the choice of case markers is insignificant: when a generated sentence contains mistakes in grammatical elements, they often lead to severe unintelligibility, sometimes resulting in a different semantic interpretation from the intended one.
having a model that makes reasonable predictions about which case marker to generate given the content words of a sentence, is expected to help MT and generation in general, particularly when the source (or native) and the target languages are morphologically divergent.
