Morphology Matters: A Multilingual Language Modeling Analysis (2021.tacl-1)

Copied to clipboard

Challenge: Existing studies on inflectional morphology disagree on whether or not it makes languages harder to model.
Approach: They propose to use a corpus of 145 Bible translations in 92 languages to investigate whether inflectional morphology makes languages harder to model.
