Paper accepted for GroupSight workshop at HCOMP 2017
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.
