Retweeting—re-posting original content without any change—is a popular function in Twitter and can be seen as amplifying the spread of original messages. This makes retweet prediction a crucial task when studying online information diffusion processes during a time of crisis such as the current COVID-19 pandemic The retweet prediction task in the challenge is based on the TweetsCOV19 dataset <https://data.gesis.org/tweetscov19/>--- a publicly available dataset containing more than 8 million COVID-19-related tweets, spanning the period October 2019 to April 2020.
