I'm Yusuke Matsubara. I work at the Decentralized Big Data Team at Riken, Tokyo, Japan.
I have worked on statistical modeling of natural language and its applications to support document authoring. Recent projects I have worked on include mining of less frequent patterns in a text, semantic parsing of Japanese clinical texts, quantitative analysis of Wikipedia contributors. My research interests cover other areas of computational linguistics at large.
In my spare time, I enjoy contributing to free software and free content movement. If you are interested in those activities, see also my other online presence.
