New Book: Text Data Management: A Practical Introduction to Information Retrieval and Text Mining,
by ChengXiang Zhai and Sean Massung, ACM and Morgan & Claypool Publishers, July 2016.

Teaching two MOOCs on Coursera (which use the book above as the main reference book) :
Research Interests: My general interests are in developing all kinds of novel Intelligent Information Systems (e.g., intelligent search engines, recommender systems, text analysis engines, and intelligent task assistants) to help people manage and exploit large amounts of data (i.e., "big data"), especially text data. I am particularly interested in building such intelligent systems for improving health, medical care, education, and accelerating scientific discovery, and bulding them based on theoretically sound frameworks, models, and algorithms that are also effective empirically. My current interests include Intelligent Information Retrieval, Text Data Mining, Applied Machine Learning, Optimization of Human-Computer Collaboration, Biomedical and Health Informatics, and Intelligent Educational Systems.
