The purpose of this work is to label COVID-19 Vaccine English tweets that are posted on Twitter about Covid19 all over the world. In the platform we will show a tweet and the annotator will examine if the tweet contains a factual claim. Based on the answer (YES, NO, or Don’t know or can’t judge), the annotator might need to answer more questions.
A detailed annotation instructions with example tweets can be found here: Annotation Instructions Tutorial
Thanks a lot for helping us label the tweets!
