Research Interests

My research is focused on natural language processing, machine learning, and artificial intelligence. My research group investigates:

Learning from large data sets: Exploding amounts of data are creating new opportunities for artificial intelligence. Our group is focused on unsupervised and semi-supervised learning from large data sets, in particular the Web. We interested in:

Applications of knowledge extraction from the Web: We're exploring applications of our work on extracting and synthesizing the Web's information, in order to enable new and improved Web search experiences. E.g.:


See also our project page for Web Information Extraction, an NSF-funded project related to the above directions, focused on scaling and integrating knowledge extracted automatically from the Web.
