Basser Seminar Series

User Experience and System Issues

Professor Joseph A. Konstan
President ACM SIGCHI, University of Minnesota

Tuesday 13 June 2006, 4-5pm (Note different day)

Basser Conference Room (Madsen Building, Room G92)


Over the past decade, recommender systems employing collaborative filtering technology have evolved from research proofs-of-concept to commonplace components of e-commerce web sites and direct marketing. At the same time, research has moved forward to embrace more sophisticated algorithms and more detailed exploration of the user experience. This talk introduces recommender systems and the algorithms and interfaces used to construct them. It then reviews recent highlights from the 13-year-old GroupLens
Research Project, including advances in algorithms, innovations in user interfaces for enhancing user experience, experiments in applying recommender systems to digital libraries, and developments in leveraging the power of on-line communities to construct and maintain artifacts of lasting value.

Speaker's biography

Joseph A. Konstan is Professor of Computer Science and Engineering at the University of Minnesota. His research addresses a variety of human-computer interaction issues, including personalization (particularly through recommender systems), eliciting on-line participation, and designing computer systems to improve public health. He is probably best known for his work in collaborative filtering recommenders (the GroupLens project), and for his work in online HIV prevention. He is co-author of Word of Mouse: The Marketing Power of Collaborative Filtering, a book that reviews three dozen good and poor examples of personalization in research and deployed systems.

Dr. Konstan received his Ph.D. from the University of California, Berkeley in 1993. He is an ACM Distinguished Lecturer and a former IEEE Distinguished Visitor. He is President of ACM SIGCHI, the 4500-member Special Interest Group on Human-Computer Interaction, and serves on two of the ACM's five governing boards. Dr. Konstan is an active consultant who has worked for more than 15 companies on issues related to human-computer interaction, personalization, and general software issues. He has traveled and lectured extensively, giving over 200 talks in more than 25 countries worldwide. Further details:
