IST 597 Special Topic (Srping 2019)

Crowdsourcing & Crowd-AI Systems


  1. Please bring a laptop to class.
  2. Please finish each week's required reading (2 to 3 papers) before class.
  3. We will have a quiz, containing 2 to 3 simple questions about that week's reading, at the beginning of each class. These quizzes must be completed while in class and without consultation with online resources.
  4. If you cheat, you fail the course. You are allowed to discuss assignments with others, but nothing written (on paper, in electronic format, on whiteboards, etc) should exist after these discussions.
