Crowdsourcing Guide

This guide walks you through running annotation tasks on crowdsourcing platforms like Prolific and Amazon MTurk.

Platform Setup

Authentication for Crowd Workers

  • Adjudication - Resolve disagreements between multiple annotators
  • MACE - Statistical estimation of annotator competence and label recovery
