Description

Since 1992, the GroupLens Research Project has been exploring ways to use the opinions of a community of users to help each member more effectively filter content in a personalized way. This talk reviews the history of the GroupLens project, including its Usenet News and MovieLens research recommenders, and the experiences of five years of commercial recommender applications. It focuses on major research results and experiments with new and different interfaces to support communities of recommender system users. A variety of research papers on the topic can be found at www.grouplens.org, and MovieLens, our current research system, can be found at www.movielens.org.
