Crowdsourcing: Background and Working Definitions
Definition: Although crowdsourcing can have many meanings, we define it here to mean breaking down large tasks into small ones that can be performed asynchronously.
- The Best Practices entry for crowdwork, developed last year and reposted on Class 3, classifies crowdwork three ways:
First, a large group of workers may do microtasks to complete a whole project; the best-known platform in this arena is Amazon Mechanical Turk. Second, companies may use cloudwork platforms to connect with individual workers, or a small group of workers, who then complete larger jobs (e.g., Elance and oDesk). Finally, a company may run “contests,” where numerous workers complete a task and only the speediest or best worker is paid (e.g., InnoCentive and Worth1000). In some contests, the company commits to picking at least one winner; in others, there is no such guarantee.

Although the idea of crowdsourcing has been around for many years, the Internet has made it much easier, cheaper, and efficient to harness the power of crowds. The power of crowds was popularized in 2005, James Surowiecki published a book entitled, The Wisdom of Crowds, which purported to show how large groups of people can, in many cases, be more effective at solving problems than specialists.. The following year, journalist Jeff Howe, coined the phrase "crowdsourcing" to refer to work that was performed by the "masses" online. Since Howe's article was published in 2006, numerous authors have written books on crowdsourcing, each choosing to focus on different aspects of the topic. Howe himself took up the topic in 2008, proclaiming crowdsourcing to be a panecea--a place were a perfect meritocracy could thrive.[ Howe examined crowdsourcing from a variety of perspectives: what benefits it can provide, what kinds of tasks it can accomplish, and the potential changes it may bring about. Howe's diagnosis of crowdsourcing was positive--in it he saw many potential solutions and few potential problems.
Others have followed Howe's lead in describing the benefits of crowdsourced work. Clay Shirky has published two books--Here Comes Everybody (2008) and Cognitive Surplus (2010)--in which he describes how technology does more than enable new tools, it also enables consumers to become collaborators and producers. Although Shirky's book are not expressly about crowdsourcing per se, they mirror the optimism Howe expresses, both in terms of collaborative enterprises and the Internet's power to enable them.
While some focused on the potential consumer revolution, others examined the business-related aspects of crowdsourcing. In Groundswell (2008), Charlene Li and Josh Bernoff focus on how to most effectively use crowdsourcing to advantage businesses. The authors highlight how users bases of products can undermine a product or brand. As a result, the authors propose businesses use the "groundswell" to their advantage, fostering communities that can provide valuable feedback and economic payoffs. Other authors
A Framework For Analyzing Issues in Crowdsourcing
1. How do concerns of reputation and identity play into crowdsourced work quality?
- tasks where want rep known, others not known
- phone card/coupon system
- Verification of workers is becoming a problem (can access the linked article through Harvard Library).
2. Can we ensure work quality using (semi)automated mechanisms?
- Some have attempted to use crowdsourcing to ensure quality on crowsourced tasks using cheat detection mechanisms. This can be done for both routine and complex tasks.
3. Can we enhance work quality using a targeting system
- Amazon rec, ebay sytle, MT?, differentiate tasks?
