A Survey of Crowdsourcing on Social Media Platforms
PhD Qualifying Examination Title: "A Survey of Crowdsourcing on Social Media Platforms" by Mr. Chen CAO Abstract: Crowdsourcing as a form of Human Processing Unit(HPU) is a new computation paradigm to solve CPU-hard problems. Typically, in a crowdsourcing application, the CPU-hard problems are decomposed into a batch of sub-tasks, and the sub-tasks are distributed to the crowds via a marketplace provided by the crowdsourcing platform. The final knowledge are harvested by aggregating the answers from the crowds. With the rapid development of social media/network services, as well as the development of mobile devices, the power of crowdsourcing is no longer constrained in the general purpose platforms. On social media and some of social network services, it is practical to enroll normal users as crowdsourcing "workers" actively, with both quality and cost control. In this survey, we will first introduce the fundamental principles in crowdsourcing application and algorithms. Then we will illustrate the current research on the topic of crowdsourcing on social media platforms, including the system framework and essential algorithms for controlling the quality and the cost. In the end, we brief about the directions of future research on this topic.
