Introduction of the tutorial topics and presenters Microtask crowdsourcing fundamentals

Microtask crowdsourcing platforms, as one of the most popular instance of social computing technologies, are increasingly used to support massively collaborative projects on semantic content management. In this tutorial we will introduce the most popular approaches to microtask crowdsourcing for Semantic Web problems, as a mean to realize hybrid human-machine content management architectures. We will explain the core notions and technologies, including Amazon Mechanical Turk, CrowdFlower and specifically purposed tools building upon the functionality of these platforms. We will address questions related to quality assurance, resource management, and workflow design, and discuss a series of technical and socio-economical challenges and open issues related to the application of microtask crowdsourcing in given Semantic Web scenarios. **Tutorial webpage: https://sites.google.com/site/microtasktutorial/**
