Yusuke Matsubara

I'm Yusuke Matsubara. I work at the Social ICT Research Center at The University of Tokyo in 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.
