Dr. Luther accepted an invitation to serve as program co-chair for ACM Collective Intelligence 2018, to be held July 7-8, 2018 in Zurich, Switzerland, and co-located with HCOMP 2018.
Our paper on GroundTruth, a system that allows experts to collaborate with crowds on image geolocation tasks, was accepted for the second GroupSight workshop at HCOMP 2017. Congratulations to Crowd Lab alumni Rachel Kohler and John Purviance, co-authors on the accepted paper.
Here’s the abstract for the paper:
Geolocation, the process of identifying the specific location where a photo or video was taken, is an important task in verifying evidence for investigations in journalism, national security, human rights, and other domains. However, experts typically perform geolocation work as a time-consuming, manual process. This paper introduces GroundTruth, a web-based system that leverages the powerful vision system of crowd workers to support experts in image geolocation tasks. We describe the technical contributions of GroundTruth and present preliminary results from an evaluation with expert geolocators and novice crowds.
The Crowd Lab’s research on crowdsourced investigations was featured in an article, Crowd Sleuthing: Harnessing the Power of Crowds, by our local NPR affiliate, WVTF & Radio IQ. Dr. Luther is quoted multiple times discussing the lab’s Photo Sleuth and GroundTruth research projects, as well as general potential risks and benefits of crowd sleuthing. The story also includes an accompanying radio broadcast.
