Managing the Wisdom of Crowds on Social Media Services

Abstract

Recently, the “Wisdom of Crowds” has attracted a huge amount of interests from both research and industrial communities. For the current stage, most of focus has been put on several specific crowdsourcing marketplaces like Amazon MTurk or CrowdFlower, on which “requesters” publish tasks and “workers” select tasks according to their own benefits. However, users on social media services can also serve as candidate “workers” for crowdsourcing tasks, and it is possible for the “requesters” to actively manage the quality and cost of such crowds.

In this tutorial, we will first review the basic concept of crowdsourcing and its applications. Then, we will discuss the current popular crowdsourcing platforms and several interesting crowdsourcing related algorithms. Finally, we will discuss the benefits of using social media services as the crowdsourcing platform and propose several research challenges on managing the wisdom of crowds on social media.
