My Curriculum Vitae


I obtained my Ph.D. from Computer Science Department, Rensselaer Polytechnic Institute (RPI).
My advisor is Prof. Heng Ji at Blender Lab.
My Ph.D. thesis topic is "Moving from News to Social Media: Unsupervised Knowledge Enrichment for Event Extraction".

Generally, my research interests lie in Natural Language Processing and Machine Learning, especially Information Extraction, Information Retrieval and Question Answering. I have conducted research on the following NLP tasks:
  • Information Extraction: identify information from bank records, news and social media messages
  • Question Answering: automatically understand and answer natural language questions
  • Document Retrieval: efficiently retrieve similar documents in big data
  • Tweets-News linking: bridge the lexical semantics between tweets and news articles
  • Sentiment Analysis: identify user sentiment of online reviews, tweets and forums
I have the experience to tackle various NLP tasks in different genres including bank records, news, tweets, Facebook messages, forums, clinical documents and e-commerce product descriptions.

Research Interests:
  • Information Extraction
  • Information Retrieval
  • Question Answering
  • Sentiment Analysis
