Title: Crowdwork’s Invisible Engine: Valuing the Organic Collaboration in Crowdsourcing Labor Markets
This presentation shares key findings from joint research with Siddharth Suri that examines workers’ experiences of what we call crowdwork—paid, short contract tasks, distributed to a large pool of online workers (aka the ‘crowd’) through crowdsourcing platforms, that might otherwise go to a full time employee. Combining 21 months of ethnographic fieldwork and interviewing with computational analysis of backend metadata, we compare the cases of workers in India and the United States, to understand the cultural meaning, political implications, and ethical demands of crowdwork. This talk lays out the evidence we have that, despite the designs of crowdsourcing to maximize efficiencies through atomized, autonomous workflows, the most active crowdworkers are not the independent workers they are assumed to be. Instead, workers collaborate extensively to address both technical and social needs generated by the platforms they work on. Our work suggests that crowdsourcing’s successes are driven as much by the invisible labor of organic collaboration—connections organized by workers—as the matching and routing capacities of an API. While our study includes examples of what we call “engineered collaboration,”—interaction organized by the platform—the persistence of organic collaboration even in these systems suggests that there’s an untapped reservoir of productivity and better work conditions to be found in models of facilitated organic collaboration. We argue that before we can improve the technical capacities of crowdsourcing systems, we need methodologies that help us get a clearer sense of the people doing this work, what it means to them, and how it fits into their daily lives. In short, we should recognize that crowdsourcing systems are not, simply, technologies. In the case of crowdwork, crowdsourcing platforms are sites of employment with complicated social dynamics that, ultimately, hold value beyond a single moment of task completion.

Mary L. Gray is a Senior Researcher at Microsoft Research. She maintains an appointment as Associate Professor in the Media School, with adjunct appointments in American Studies, Anthropology, and Gender Studies, at Indiana University. She studied Anthropology before receiving her Ph.D. in Communication from the University of California, San Diego in 2004. Her research looks at how media access and everyday uses of technologies transform people's lives. Her last book, Out in the Country: Youth, Media, and Queer Visibility in Rural America, looked at how young people in the rural United States use media to negotiate their sexual and gender identities, local belonging, and connections to broader, imagined communities. Mary's current book project, co-authored with computer scientist Siddharth Suri, combines ethnography, interviews, survey data and large scale data analysis of four crowdsourcing platforms operating in the United States and India to examine workers’ experiences of digital labor and the future of employment in platform economies.

Title: Human Cooperation

David Rand is an assistant professor of psychology, economics, and management at Yale University, and the director of Yale University’s Human Cooperation Laboratory. His research combines a range of theoretical and experimental methods in an effort to explain the high levels of cooperation that typify human societies, and to uncover ways to promote cooperation in situations where it is lacking. He received his B.A. in computational biology from Cornell University in 2004 and his Ph.D. in systems biology from Harvard University in 2009, and was a post-doctoral research in Harvard University’s psychology department from 2009 to 2013.

HCOMP 2015 Sponsorship Levels & Benefits

Two sources of income pay for HCOMP conference expenses: registration fees paid by the attendees and sponsorships from corporations, universities, and other institutions. Sponsors’ funds allow HCOMP conferences to limit increasing registration, especially for students and the assistance provided by our sponsors is greatly appreciated.

HCOMP 2015 will provide benefits to sponsors in exchange for their financial support. To build awareness of sponsorship, we will publically acknowledge all sponsors in the opening and closing plenary sessions, on the conference website, in the proceedings, and final program. We will list the sponsors in order of contribution. We will also acknowledge Champion and Benefactors sponsors for their contribution to well attended social events including receptions, the conference banquet/party, coffee breaks, and student dinners.

Sponsors are given the opportunity to provide information (e.g., brochures) directly to HCOMP 2015 attendees. Champion, Benefactor, and Contributor sponsors are invited to present demonstrations of their relevant technology. HCOMP 2015 will also accommodate sponsors interested in recruiting conference attendees. Sponsors may also receive a complimentary HCOMP 2015 registration.

HCOMP 2015 offers four levels of sponsorship: Champion, Benefactor, Contributor, and Friend.

  • Champions ($7,500 or greater contribution)

  • Benefactors ($5,000 or greater contribution)

    Lead Genius
  • Contributors ($2,500 or greater contribution)

    Lead Genius
  • Friends (contribution of less than $2,500)
