Our mission is to develop innovative and robust natural language processing technologies that improve machine understanding of human language.

We conduct research in the areas of automatic text summarization, language generation, social media analytics, semantics, and machine Learning for NLP. Much of the technologies involve natural language processing, machine learning, probabilistic graphical models, and deep learning as applied to large-scale text data.

Notes to Prospective Students.
