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.
