Pen Picture

I am Professor of Computational Linguistics and Natural Language Processing of the University of Tokyo and Professor of Text Mining of the University of Manchester, UK.
   My first degree, from Kyoto University, was in Electronics and I have an MSc and a PhD from Department of Electrical Engineering, Kyoto University. I was Associate Professor of Kyoto University from 1979 to 1988 with a break at CNRS Grenoble, France as invited senior researcher in 1981-1982. Before taking up the position at the University of Tokyo, I was Professor of Computational Linguistics of University of Manchester Institute of Science and Technology (UMIST) in the UK from 1988 to 1995, where I kept the position of Research Professor until 2001. At July 2005 I was appointed Director of National Center for Text Mining (NacTeM)
@of the UK in Manchester, as well as Professor of the University of Manchester.  Since 2008, I am Scientific Director of the centre. I have also been Advisory Professor of Beijing University of Post and Telecommunication (BUPT), China since May, 2005.

I have been a permanent member of International Committee of Computational Linguistics (ICCL) from 1994.@I was Vice-President (2005) and President (2006) of ACL (Association for Computational Linguistics), and President (2008) of AFNLP (Asian Federation of Natural Language Processing).

I was awarded IBM Science Award in 1988, SEYMF Visiting professorship in 2000, Daiwa-Adrian Prize for the project jointly carried out by Dr.S.Ananiadou (University of Manchester, UK) in 2004, IBM Faculty Award in 2005, and Achievement Award (Japan Society of Artificial Intelligence) in 2008.

Research Interests

While language can be studied from various points of view and by diverse methods, I am interested in formalizing human language by using the concept of computation that has emerged in computer science since the mid of the 20th century, and in combining the formalization with other mathematical models of language, in particular, statistical language models. I am also being involved in applying such theoretical models of language to practical application such as Information Extraction from texts, Intelligent Information Exploitation in Web, and Text Mining for Biology, Multilingual Information Exploitation, and Machine Translation.
    After the JSPS project (1995-2000) focused on grammar formalisms and parsing completed, our research team is now involved in several projects such as GENIA (Text Mining for Biology), aNT (Advanced Natural Language Processing and Text Mining) , and U-Compare (UIMA-based NLP toolkits). These projects are to show viability of theoretically sound grammar formalisms and NLP frameworks in practical application.
