• Question Answering
• Knowledge Discovery from the Web
• Information Retrieval & Text Processing
• Machine Transliteration

Short Bio.

I have been working in NICT as an expert researcher since Oct. 2005. I was involved in the "Japanese-Chinese machine translation project" and charge of unknown word translation including machine transliteration. Since 2008, I had been working on knowledge acquisition from Wikipedia, especially for acquisition of multilingual semantic knowledge such as hyponymy relations. I am currently interested in non-factoid question answering using semantic knowledge.
