Additions

  • Expand your morphology to cover at least 5 more elements of some paradigm(s). This can be anything from additional verb or noun morphology, to adding all the forms of all the determiners (articles, demonstratives, etc.), to implementing nominal morphology on adjectives (e.g., if your language allows adjectives to be substantivised, which you'll want to add a tag for too).
  • At least 3 new disambiguation rules that make the output of your tagger more accurate.
  • At least 2 new transfer rules that make more of the output of your MT system closer to an acceptable target translation.
