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") and augment human intelligence, 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. For a more detailed view of my research interests, you may want to take a look at the slides of some of my recent talks.

Publications & Recent Talks (Google Scholar Profile, DBLP Profile)

The Book Text Data Management: A Practical Introduction to Information Retrieval and Text Mining, ChengXiang Zhai and Sean Massung, ACM and Morgan & Claypool Publishers, July 2016. has now been translated into Chinese (see the Chinese version). The book is the main reference book for two MOOCs on Coursera that I'm teaching: (1) Text Retrieval and Search Engines ; (2) Text Mining and Analytics.
