Title: Precision Crowdsourcing: Leveraging the Contributory Potential of User Feedback
Speaker: Loren Terveen (CS, University of Minnesota)
Date: Wednesday, March 5
Time: 12-1pm
Room: GHC 6501

I will discuss my group’s emerging work on Precision Crowdsourcing: crafting targeted requests to information consumers with the goal of closing the loop and turning them into contributors. I will talk about the general approach, then illustrate it through a project we’ve done in Cyclopath. Specifically, we designed and studied several mechanisms Cyclopath users could use to give feedback on bicycling routes they had requested. We analyzed naturally occurring textual route feedback, and found that it contained a significant amount of information that would be useful to the system, e.g., evaluations of road segments and suggestions of alternative routes. We then designed a new UI to let users provide and explain feedback, and ran an experiment that showed promise that users would give and explain route feedback, and that the system could extract useful information from it.

Loren Terveen is a Professor of Computer Science at the University of Minnesota. His research interests include a variety of topics in human-computer interaction and social computing. He helped develop one of the early recommender web sites (PHOAKS) and recently has led projects that have: revealed new information about how valuable content is created on Wikipedia and the lifecycle of Wikipedia users, produced and deployed new interface designs to enhance participation in online communities, developed a novel location-aware messaging system, and combined wiki and geographical information systems technologies to create social web sites that let people enter and access information about places in their local communities. 

Prof. Terveen received his Ph.D. 1991 from the University of Texas at Austin, then spent 11 years at Bell Labs and AT&T Labs before joining the University of Minnesota. He has served the human-computer interaction community in various leadership roles, including as co-chair of the CHI and IUI conferences, program chair of CSCW, and a member of the SIGCHI Executive Committee.
