CosmoQuest has a large presence at this year’s AGU in Washington, DC, from Dec 10-14, 2018. We have a number of posters and presentations by our team members. If you’re there, come by and check out what we’ve been doing!
Lead Programmer Tanner Burge-Beckley will be presenting PA23C-01: Analyzing Integrity of Citizen Science Data
When: Tuesday, 11 December 2018 13:41 – 13:44
Where: Walter E Washington Convention Center – eLightning Theater I
Description: One of the most important steps in science analysis is data validation. In observational environments, this may mean having two observatories document the same supernova, or using observations of standard stars to place asteroid measurements on a standard magnitude system. Regardless of how data validation is achieved, it typically requires the standardizing of data and comparing measurements across multiple programs. In citizen science where the data used are obtained by amateur astronomers and other volunteers, data validation has the added complexity of combining data acquired by different individuals as well as systematically accounting for common errors that arise. In this presentation, we examine how the CosmoQuest citizen science platform validates image annotations submitted by volunteers. We review strategies for combining data from multiple people, ways to identify common errors that must be cleansed from the data, and techniques for comparing expert data with volunteer data.
