NASN 2021: Grand Challenge

> > Back to NASN 2021

North American Social Network Conference: 2021 Grand Challenge 

The NASN 2021 Grand Challenge asks researchers to explore a dataset and share their insights. The datasets selected for the Grand Challenge  are typically both fairly new and not fully explored. There are no preconceived notions of what researchers should find or what conclusions should be reached. The goal is for the researchers to present what they determine are key insights or unique findings. 

For 2021, we have created a new Twitter dataset around COVID disinformation.  The Federation of American Scientists ( recently published two papers around vaccines and herd immunity.  We have merged and expanded upon that work to produce a single dataset. The data was pulled using the Twitter data access API.  The data has not been cleaned or altered. 

CAUTION:  DO NOT explore links in the tweets.  Some are known to point to viruses and malware.

The selection criteria are as follows:
Date Range:
  •  Sept  1st  to Oct 23rd, 2020
  • AstraZeneca
  • “Astra Zeneca”
  • AZD1222
  • ·COVID
