Munson, S., Zhou, D. X., & Resnick, P. (2009). Designing Interfaces for Presentation of Opinion Diversity. CHI 2009
News aggregators rely on links and users votes to se- lect and present subsets of the large quantity of news and opinion items generated each day. Opinion diver- sity in the output sets can provide several benefits. We outline a range of diversity goals and discuss user reac- tions to a pilot implementation that selects for diversity as well as popularity. We then describe plans for re- search on alternative presentations and their impacts on users.
