Yutaka Sasaki received the B.E., M.Eng., and Ph.D. in Engineering from the University of Tsukuba, Ibaraki, Japan, in 1986, 1988, and 2000, respectively. In 1988, he joined the NTT Communications and Information Processing Laboratories, Yokosuka, Japan. From 1991 to 1994, he studied a meta-level control architecture for rule-based CAI systems at the NTT Network Information System Laboratories. From 1994 to 2004, he was with the NTT Communication Science Laboratories. From 1995 to 1996, he spent one year at the Intelligent Software Group, Simon Fraser University, Canada as a visiting researcher. During the days with NTT CS Labs, he devised hierarchically-sorted Inductive Logic Programming systems, RHBs, and applied them to Natural Language Processing tasks, especially Information Extraction tasks. He also developed world's first practical *Japanese* Question Answering (QA) system, SAIQA, based on large-scale newspaper corpora (9 years of Mainichi Newspapers, approx. one million articles). The system was exhibited to the public at the Open House in June 2001. Another his achievement was world's first fully trainable Japanese QA system, SAIQA-II, where its key components are automatically constructed from QA sample data. The system was exhibited to the public at the Open House in June 2002. In June 2004, he was seconded to ATR Spoken Language Translation Research Laboratories. He investigated Statistical Machine Translation and Machine Learning approach to Cross-Lingual Question Answering systems. From August 2006, he joined the BOOTStrep Project, University of Manchester, UK. Since November 2009, he is with Toyota Technological Institute, Nagoya, Japan, where he is a professor at the School of Advanced Science and Technology. He is a member of the Association for Computational Linguistics, the Japanese Society for Artificial Intelligence, the Information Processing Society of Japan, and the Association for Natural Language Processing.
