“The recognition and accurate translation of proper nouns, many of which are bilingually non-compositional, are a major issue⟳ in MT and other NLP applications. This is especially true for Chinese and Japanese, whose scripts present⟳ linguistic and algorithmic challenges not found in other languages.”
