Oh, I expect that you'd use NN NLP to do accurate parsing/tagging/NER then write rules based on the output of that parsing. If you look at https://explosion.ai

Oh, I expect that you'd use NN NLP to do accurate parsing/tagging/NER then write rules based on the output of that parsing. If you look at https://explosion.ai/demos/displacy https://explosion.ai/demos/displacy, you can see the high-level information you can extract from sentences nowadays, which better matches our understanding of how grammar rules work. And that's an approach that does generalize to languages like Japanese.
