Research Interests

My research areas are artificial intelligence and natural language processing (NLP). My research with students and colleagues has been in discourse processing, pragmatics, and word-sense disambiguation. A major concentration of our research is "subjectivity analysis", recognizing and interpretating expressions of opinions and sentiments in text, to support NLP applications such as question answering, information extraction, text categorization, and summarization.

Recent Activities

Area Co-Chair, Social Media and Sentiment Analysis, ACL 2012

Action Editor, for the new new journal, Transactions of the ACL. TACL is a fairly dramatic change in the ACL publication model. TACL will publish conference-length papers, with fast turnaround reviews, but with journal-style reviewing (in particular, a revise and resubmit option), and with rolling submissions (submissions allowed on the first day of every month). Papers accepted at TACL will be eligible for presentation at the ACL main conference.
