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.
Publications, Corpora, Software, and Bibliography
A new version of the MPQA corpus was released January 2009 which includes attitude annotations (such as positive and negative sentiments and arguing) as well as target span annotations. Both versions are available at the resources link below.
