work in my research group. Specifically, I will present three approaches to
improve work quality and increase the complexity of work that can be
completed on paid microtask platforms: 1) Our work on the Shepherd system
demonstrates how timely feedback and self-assessment can lead to better work
and higher worker perseverance. 2) Our Turkomatic system recruits crowd
workers to aid requesters in planning and solving complex jobs. Requesters
can view the status of workflows in real time; intervene to change tasks and
solutions; and request new solutions to subtasks from the crowd. 3) Finally,
I will introduce an alternative mechanism for crowdsourcing tasks that
require specialized knowledge or skill from workers: communitysourcing — the
use of physical kiosks to elicit work from specific populations.
Bio: Björn Hartmann is an Assistant Professor at UC Berkeley in EECS,
