  Online news and information sources are convenient and accessible ways to
learn about current issues. For instance, more than 300 million people engage
with posts on Twitter globally, which provides the possibility to disseminate
misleading information. There are numerous cases where violent crimes have been
committed due to fake news. This research presents the CovidMis20 dataset
(COVID-19 Misinformation 2020 dataset), which consists of 1,375,592 tweets
collected from February to July 2020. CovidMis20 can be automatically updated
to fetch the latest news and is publicly available at:
https://github.com/everythingguy/CovidMis20. This research was conducted using
Bi-LSTM deep learning and an ensemble CNN+Bi-GRU for fake news detection. The
results showed that, with testing accuracy of 92.23% and 90.56%, respectively,
the ensemble CNN+Bi-GRU model consistently provided higher accuracy than the
Bi-LSTM model.
