Research Interests

My research interests lie in Data Mining, Natural Language Processing and Social Computing. In particular, I am interested in:
(i) Knowledge representation and reasoning, which involves extracting, interpreting and transforming digital content into structured knowledge representations; (ii) Discovering and leveraging user intents or intentions from their natural language interactions for various downstream NLP tasks; and (iii) Understanding Human Behavioral characteristics from heterogeneous data sources for interdisciplinary applications such as public health, emergency response and marketing.
