Become a sponsor to mhagiwara

Hi! I'm Masato, working as an independent NLP/ML engineer and researcher. I work with world-class institutions and start-ups including Allen Institute for AI and RIKEN AIP.

I love language and technologies, and help people connect the two. I work on a book and a blog to teach NLP to the world, and several open-source projects including GitHub Typo Corpus, TEASPN, NanigoNet, and CC-KEDICT.

In order to keep working on open-source projects and to stay independent, I'm looking for sponsors!
