Research Interests

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.
