We test these claims by comparing character-level models to an oracle with access to explicit morphological analysis on twelve languages with varying morphological typologies. Our results highlight many strengths of character-level models, but also show that they are poor at disambiguating some words, particularly in the face of case syncretism. We then demonstrate that explicitly modeling morphological case improves our best model, showing that character-level models can benefit from targeted forms of explicit morphological modeling. %R 10.18653/v1/D18-1278 %U https://aclanthology.org/D18-1278 %U https://doi.org/10.18653/v1/D18-1278 %P 2573-2583
