GroupLens Research is a research lab in the Department of Computer Science and Engineering at the University of Minnesota, Twin Cities specializing in recommender systems, online communities, mobile and ubiquitious technologies, digital libraries and local geographic information systems.

History

In 1992, John Riedl and Paul Resnick attended the CSCW conference together. After they heard keynote speaker Shumpei Kumon talk about the information economy[1], they originated the idea for a collaborative filtering system used for Usenet news that they'd later call GroupLens. GroupLens allowed for postings to be rated on a scale. These ratings allowed for the system to predict how much an individual would like an article, based on their ratings of previous articles. A feasibility test was done between MIT and the University of Minnesota and the published results were part of the CSCW conference of 1994.[2]

In 1995, GroupLens Research expanded the team and hired Joseph Konstan, Bradley Miller, and later others, to re-implement GroupLens over the internet with a centralized server, called the Better Bit Bureau.[3] Later, in the Spring of 1996, the first workshop on collaborative filtering was put together by Resnick and Hal Varian at the University of California, Berkeley. There, researchers from GroupLens and other projects that were studying similar systems came together to explore what each other were doing.

  • NetPerceptions: David Gardiner, Steven Snyder, Brad Miller, John Riedl, Joseph Konstan
  • E-commerce awards[4]
  • 1996-2004. Commercialized tech from GroupLens

Meanwhile, research continued at the University of Minnesota where the the area of human–computer interaction became GroupLens Research, named after the first system of collaborative filtering by Riedl and Resnick. The department was given its first grant from the National Science Foundation to study algorithmic issues in collaborative filtering[5].

When the EachMovie site closed in 1997[citation needed], the researchers behind it gave out, for free, the anonymous rating data behind the site. The GroupLens researchers Brent Dahlen and John Herlocker took advantage of this dataset and had the MovieLens movie recommendation engine running within a few months. Since then, the site has had substantial success in attracting publicity and users and its data set has been used in numerous research papers.[citation needed]

  • ABC Nightline[6]

In 2002 the group expanded into social computing and online communities with the addition of Loren Terveen.

  • Phoaks paper[7], Loren was doing other types of recommendations -- more socially oriented
  • Collaborations with Bob Kraut and Sara Kiesler of CMU. Incorporated more social psychology work (ConversationLens)[8]
  • The Value of Information (Mamun)[9]
  • Also Paul Resnick, and Yan Chen of UMich. More of an economics perspective. User Modelling (Max, 2004)[10]
  • NYT article, John Riedl
  • Information Leakage paper (DanFr) in SIGIR[11]

GroupLens Research has since diversified from collaboriative filtering into the study of online communities[citation needed], mobile and ubiquitious technologies[citation needed], digital libraries[citation needed], and local geographic information systems[citation needed].

Contributions

  • MovieLens - Members of GroupLens Research constructed and maintain MovieLens, a non-commercial movie recommendation site that has hosted experiments in collaborative filtering algorithms[citation needed], tagging interfaces[citation needed], and other features since 1997. The datasets released by the MovieLens team have become a standard test set in the recommender systems research community
  • Wikipedia - Since their initial study into value and vandalism in Wikipedia published in 2007[12], GroupLens has provided insight wiki-work recommendations[citation needed], editing behaviors of Wikipedians[citation needed], how the encyclopedia's library is growing[citation needed] and the informal peer review system that decides what content is accepted[citation needed].
  • Cyclopath - In 2008, GroupLens member Reid Preidhorsky launched Cyclopath, a computational geowiki for local bicyclists.
