My general research area is machine learning of natural language. My recent projects have focused primarily on developing unsupervised and semi-supervised machine learning techniques for natural language processing, with the goal of reducing the amount of annotated data needed to build NLP applications and process resource-scarce languages. Areas in which my group has been working include:
natural language applications (automated essay scoring, AI for law, AI for software engineering, health informatics)
opinion and argumentation mining
anaphora and coreference resolution
