Our group’s research interests broadly lie in Natural Language Processing, Data Mining, and Artificial Intelligence, with emphasis on various kinds of question answering systems, natural language interfaces, network analysis, and human behavior understanding.
We aim to develop advanced computational frameworks that enable users to easily query big data, write compute programs, collaborate with each other, and acquire knowledge for decision making in various domains such as healthcare, education, and business. Please check out the code/data we have released!
