Crowdsourcing: From Analysis to Design to Evaluation
Loren Terveen
The University of Minnesota

In the past decade computational and communication technologies have been deployed to create new and surprisingly effective ways for large, distributed, and loosely connected groups of people to work together. There are many prominent examples, including Wikipedia, open source software projects like Linux and Apache, Amazon's Mechanical Turk infrastructure, and citizen science projects like Galaxy Zoo and Planet Hunters.

My own research into crowdsourcing and human computation combines analysis, design, implementation, and experimental evaluation. We study communities like Wikipedia, Twitter, and Pinterest to identify fundamental patterns and problems of user interaction. We maintain our own online communities, Cyclopath and Movielens. These communities serve as research platforms where we can introduce new algorithms and user interfaces and evaluate them experimentally.

I will give an overview of the problems we work on, the systems we have built, and some of our most interesting results. I also will highlight a few exciting opportunities for new research, particularly in social network analysis, geographically-based crowdsourcing, and mobile crowdsourcing.
