Note, however, that this is over-optimistic: the lexicon contains a tag-class for each word type in our testing dataset, i.e., while there can be word types not seen in the training dataset, there are no word types that are not listed in the lexicon.
this high accuracy is probably due to a large extent to the scale and quality of our morphological lexicon, and it might not be as strong with smaller lexicons; we plan to investigate this in future work.
