Research could ensure that crowd work becomes a career option, not a dead end

Carnegie Mellon scientists and other crowd work researchers issue call to action

PITTSBURGH—Crowdsourcing is an effective way to mobilize people to accomplish tasks on a global scale, but some researchers fear that crowd work for pay could easily become the high-tech equivalent of a sweat shop. Trivial work for rock bottom pay isn't inevitable, however, and they've outlined a research agenda to make crowd work both intellectually and monetarily rewarding.

Leading researchers in crowd work from Carnegie Mellon University and other institutions will present their plan, hashed out in a special workshop last spring, at the Association for Computing Machinery's Conference on Computer Supported Cooperative Work and Social Computing, CSCW 2013, Feb. 27 in San Antonio, Texas.

Finding ways to enhance collaboration, incorporate artificial intelligence and create ways for workers to build reputations are among the research challenges ahead.

"When my baby daughter was born I asked myself, 'would I be proud to see her grow up to be a crowd worker?'" said Aniket Kittur, assistant professor in Carnegie Mellon's Human-Computer Interaction Institute.

Co-authors with Kittur of the research strategy include Jeffrey Nickerson, director of the Center for Decision Technologies at Stevens Institute of Technology, and Michael Bernstein, assistant professor of computer science at Stanford University. Other leading crowd work researchers from Carnegie Mellon, Northwestern University and the University of Texas, Austin also contributed to the report, which is available for download.

The crowd work industry has expanded rapidly in recent years, with a number of vendors now offering work for people who get paid per task or who compete for prizes. A prominent vendor is Amazon Mechanical Turk, which claims more than 500,000 workers in more than 190 countries who complete tasks that, in some cases, may take only seconds to perform. Another, CrowdFlower, says it can access more than 2 million contributors worldwide. Others, such as oDesk, provide skilled labor, including web developers, designers and translators. Platforms such as Innocentive invite people to invent solutions to problems in hopes of winning a prize.

The still-young industry could grow very large because portions of almost any job — perhaps as much as 20 percent — potentially can be sent "down the wire," Kittur said. Many crowd workers are paid substantially less than U.S. minimum wage, however, and, left to market forces, the crowd workforce could remain stigmatized and exploited.

"What if I want access to the best people in the world, but for only five minutes of their time?" Kittur said. As beneficial as that might be for some businesses, that possibility will not be achieved if the crowd workplace isn't attractive for the very best workers and thinkers, he added. The call for action by Kittur and his colleagues, also discussed in a recent post on the Follow the Crowd blog, envisions three major research steps:
