Sihem Amer-Yahia on "Quality Experiments Crowdsourced" at the SIGMOD Blog
Crowdsourcing is a powerful paradigm that democratizes the creation, collection, analysis, curation, and dissemination of data, contributed by millions of individuals, who are called workers. Early crowdsourcing platforms in the context of citizen reporting and citizen sciences were dedicated to specific tasks. Today, many other platforms that expect workers with different expertise exist. Among them, we can find Turkit, Mob4hire, uTest, Freelancer, eLance, oDesk, Guru, Topcoder, Trada, 99design, Innocentive, CloudCrowd, and CloudFlower. The most popular one is Amazon Mechanical Turk (AMT) that is generic and allows any requester to post virtually any kind of task in which any worker can participate via self-appointment.
