Research Interests

  • Natural Language Processiong for Educational Applications
  • Large-scale natural language processing using the Web
  • Robust natural language processing
  • Statistical natural language processing (machine translation)
  • Natural language processing with deep learning (representation learning, deep neural network)

Current projects include large-scale natural language processing using the web, especially in the field of semantics analysis and information extraction. I am working on large corpora to extract semantic knowledge with minimal human annotation cost.

I am also interested in statistical machine translation (SMT). We are working on incorporating syntactic and semantic information to SMT framework.
