Biography

Bing Liu is a Distinguished Professor and Peter L. and Deborah K. Wexler Professor of Computing at the University of Illinois at Chicago (UIC). He received his PhD in Artificial Intelligence from the University of Edinburgh. Before joining UIC, he was a faculty member (associate professor) at School of Computing, National University of Singapore (NUS). He was also with Peking University for one year (2019-2020).

• Current Research Interests: Lifelong or continual learning, open-world AI and continual learning, continual learning language models and dialogue systems, natural language processing, Machine learning, Artificial General Intellgience (AGI).
• Previous research interests include sentiment anaysis and opinion mining, fake opinion detection, PU learning, data mining and Web mining.


• Research Publications: He has published extensively in top conferences and journals such as NeurIPS, ICML, ICLR, ACL, EMNLP, KDD, WWW, AAAI, IJCAI, TKDE, TWEB, CL, etc. His papers with citations can be found from his Google Scholar page (or his publication page or DBLP). He has also authored five books (4 monographs and 1 textbook):


1. S. Mazumder and B. Liu. Lifelong and Continual Learning Dialogue Systems. Springer, February 2024. (First ever book on the topic)
2. Z. Chen and B. Liu. "Lifelong Machine Learning." Morgan & Claypool Publishers. First edition, November 2016; Second edition, August 2018. (First ever book on the topic).
3. B. Liu. “Sentiment Analysis: Mining Opinions, Sentiments, and Emotions.” Cambridge University Press, June 2015. (An Amazon reviewer comment: Bible for sentiment analysis)
4. B. Liu. “Sentiment Analysis and Opinion Mining.” Morgan & Claypool Publishers, May, 2012.
5. B. Liu. “Web Data Mining: Exploring Hyperlinks, Contents and Usage Data.” Springer, First Edition, 2006; Second Edition, 2011.


• Research Contributions:
  1. He is best known for his pioneering work on sentiment analysis and opinion mining. His KDD-2004 paper opened up the field for research and applications. It defined the main concepts and tasks of the field. The paper won the KDD-2015 Test-of-Time award. He also published two popular books on the topic.
  2. He published the first ever paper on fake/deceptive opinion detection, which started the research of detecting deception, misinformation, and disinformation on the social media. His WSDM-2008 paper is the first on the topic and it won the WSDM-2019 Test-of-Time award,
  3. He also published the first ever paper on association rules based classification. His KDD-1998 pioneered the topic of using association rules for supervised classification, which won the KDD-2014 Test-of-Time award.
  4. He is also a pioneer researcher of lifelong and continual learning. He wrote the first ever book dedicated to the topic with his student in 2016. Recently, his group made a breakthrough (AAAI-2025 and NeurIPS-2025) that enables continual learning to achieve its theoretical upper bound accuracy.
  5. He is also a pioneer researcher of PU learning (learning from positive and unlabeled examples), Web data extraction and interestingness in data mining.
