Research Interests and Projects
BALANCE: Enhancing Diversity in News and Opinion Aggregators
Aggregators such as Digg, Reddit, and Google News rely on ratings and links to select and present subsets of the large quantity of news and opinion items generated each day. If a majority of the raters or linkers share a political viewpoint, minority viewpoints may get little representation in the results, creating an echo chamber for the majority. The goals of this research are to: 1) form alternative measures of diversity for result sets; 2) develop algorithms for selecting result sets that jointly optimize for diversity and popularity; 3) assess the impacts of alternative selection and presentation methods on people’s willingness to use an aggregation service, their exposure to diverse opinions, and the size of their argument repertoires. The results of the project will provide a better understanding of alternative notions of what it means for a set of items to be diverse or balanced, and the range of reactions that different people have to varying levels and presentations of diversity.
Online recommender systems are widely deployed as tools to guide users towards items they will like. There is a growing concern that recommender systems may be manipulated by people with a vested interest in having certain items recommended (or not recommended). This is exacerbated as it is often easy for a manipulator to create multiple online accounts to execute an attack. The goal of this project is to develop general techniques for the design of manipulation-resistant recommender systems as well as specific solutions for applications in which such a recommender could have a significant impact. (Joint work with Rahul Sami. Funded by NSF under Grant No. IIS-0812042.
We are drawing on theories and data from social psychology and public goods economics to drive design decisions about on-line communities with the goal of increasing participants' contributions to the communal good.

In 1999, I started the Community Information Corps at the University of Michigan School of Information. It brings together faculty and students who are studying how to organize information flows for community and public purposes. With support from the Packard Foundation, the Alliance for Community Technology and the Microsoft Foundation, we have offered financial assistance and professional development opportunities to alumni who pursue public interest careers. Salary supplements are also available for public interest summer internships.
I play the fiddle and guitar, and sing, mostly country and folk styles.

Paul Resnick is a Professor at the University of Michigan School of Information. He previously worked as a researcher at AT&T Labs and AT&T Bell Labs, and as an Assistant Professor at the MIT Sloan School of Management. He received the master's and Ph.D. degrees in Electrical Engineering and Computer Science from MIT, and a bachelor's degree in mathematics from the University of Michigan.
Professor Resnick's research focuses on SocioTechnical Capital, productive social relations that are enabled by the ongoing use of information and communication technology. His current projects include analyzing and designing reputation systems, ride share coordination services, and applying principles from economics and social psychology to the design of on-line communities.
Resnick was a pioneer in the field of recommender systems (sometimes called collaborative filtering or social filtering). Recommender systems guide people to interesting materials based on recommendations from other people. His articles have appeared in Scientific American, Wired, Communications of the ACM, The American Economic Review, Management Science, and many other publications.
