We are happy to announce the release of our paraphrase database Lexpanded-PPDB version 1.0, which comprises 692 million English paraphrase pairs, as well as 942 million, 628 million, and 532 million pairs for French, Spanish, and German, respectively. We do not give features for each pair due to its scale; we instead recommend users to first extract a subset for your targeted texts and then give some features for each pair within it.
A co-authored paper is accepted to this year of MT Summit [Paper].
Paper and poster presented at NAACL-HLT 2015 are now available [Expansion of paraphrase lexicons].


From 2014.04.01, I'll be working at Multilingual Translation Laboratory, Universal Communication Research Institute, National Institute of Information and Communications Technology, located in Kyoto, Japan. My research themes there will be paraphrasing, machine translation, and computer-assisted human translation.
This site is now hosted by a new Web server.
The first update after my return to Japan.
Office relocation is postponed. I'll work at the same place until the end of my project period!
My office at NRC will be relocated to another campus in early March.
Mail services of our university will be unavailable during the following timeframes due to the hardware replacement. Please make sure that you are out of these timeframes (JST, +0900) when sending me an email.

Call for participation! The technical program of the 6th NLP Symposium for Young Researchers is now available. Please feel free to come to the symposium and enjoy chatting with each other.
Call for submissions of free-and-easy poster presentation! We are delighted to announce that the 6th NLP Symposium for Young Researchers will be held under the sponsorship of the Association for Natural Language Processing in Japan. We are welcoming submissions that have potential of future innovativation.
An incredibly huge earthquake (M8.8 M9.0) and consequent tidal waves (tsunami) hit the northern east part of Japan today. But, fortunately I and all of my relatives have no damage. Many thanks go to those who worried about me. As frequent aftershocks still continue, secondary and tertiary damages are expected. I am praying for safety of people in the disaster area including my ex-supervisor Prof. Kentaro Inui and his students in Tohoku Univ.
I will stay at Institute for Information Technology, National Research Council of Canada as a visiting researcher from April 2011 to March 2013. This stay is granted by the program of Postdoctoral Fellowship for Research Abroad of Japan Society for the Promotion of Science.
All the servers including the host for will be stopped from August 20th evening to August 22th morning for the electrical maintenance of the building. But, I can receive e-mails to my university account.
I am relocated to the new department according to the reorganization of departments in our university. See aim and detail if you are interested in.
