My research focuses on handling human languages (like English or Japanese) with computers -- natural language processing. In particular, I am interested in machine learning approaches that are both linguistically motivated, and tailored to applications such as machine translation and natural language understanding. You can find more details, research page or publications page, and reference my third-person bio for talk introductions, etc..
I like developing, and have created open-source software which I have summarized here: software page. I also have had a chance to give tutorials and talks on subjects such as machine translation, neural networks, and language modeling, which are posted on my teaching page in the hope that people will find them useful.
