Crowdsourcing and human computation are emerging fields that sit squarely at the intersection of economics and computer science. They examine how people can be used to solve complex tasks that are currently beyond the capabilities of artificial intelligence algorithms. Online marketplaces like Mechanical Turk provide an infrastructure that allows micropayments to be given to people in return for completing human intelligence tasks. This opens up previously unthinkable possibilities like people being used as function calls in software. We will investigate how crowdsourcing can be used for computer science applications like machine learning, next-generation interfaces, and data mining. Beyond these computer science aspects, we will also delve into topics like the sharing economy, prediction markets, how businesses can capitalize on collective intelligence, and the fundamental principles that underlie democracy and other group decision-making processes.

NETS 213 will not be offered in the 2019-2020 school year. If you’re interested in related courses, recommend taking Julia Ticona’s course Comm 432: Digital Inequality in Fall 2019.

Course Readings
Each lecture has an accompanying set of academic papers
This is a project-based course. Instead of exams, you will do a series of hands-on assignments and a final project.
  • Weekly assignments (50%)
  • Final project (45%)
  • Participation (5%)
Late day policy
Each student has five free “late days”. Homeworks can be submitted at most two days late. If you are out of late days, then you will not be able to submit your homework. One “day” is defined as anytime between 1 second and 24 hours after the homework deadline. The intent of the late day policy it to allow you to take extra time due to unforseen circumstances like illnesses or family emergencies, and for forseeable interruptions like on campus interviewing and religious holidays. You do not need to ask permission to use your late days. No additional late days are granted.
Course materials
Students should expect to spend around $50-$100 of their own money on MTurk or other crowdsourcing platforms. If this will cause you undue financial hardship, please let the instructor know.
