Yo Ehara, Ph.D.
I am a researcher at Artificial Intelligence Research Center (AIRC), National Institute of Advanced Industrial Science and Technology (AIST), Japan. My research interests include natural language processing (NLP), especially in educational NLP using item response theory and machine learning.
Previously, I was an project assistant professor at Graduate School of System Design, Tokyo Metropolitan University, researcher at National Institute of Information and Communications Technology, postdoc at National Institute of Informatics (JSPS PD, in Prof. Miyao group), in reverse chronological order. I obtained my Ph.D. (Information Science and Technology) in the University of Tokyo, supervised by Prof. Hiroshi Nakagawa, in September 2013.
