Query: CoVERT: A Corpus of Fact-checked Biomedical COVID-19 Tweets   Over the course of the COVID-19 pandemic, large volumes of biomedical
information concerning this new disease have been published on social media.
Some of this information can pose a real danger to people's health,
particularly when false information is shared, for instance recommendations on
how to treat diseases without professional medical advice. Therefore, automatic
fact-checking resources and systems developed specifically for the medical
domain are crucial. While existing fact-checking resources cover
COVID-19-related information in news or quantify the amount of misinformation
in tweets, there is no dataset providing fact-checked COVID-19-related Twitter
posts with detailed annotations for biomedical entities, relations and relevant
evidence. We contribute CoVERT, a fact-checked corpus of tweets with a focus on
the domain of biomedicine and COVID-19-related (mis)information. The corpus
consists of 300 tweets, each annotated with medical named entities and
relations. We employ a novel crowdsourcing methodology to annotate all tweets
with fact-checking labels and supporting evidence, which crowdworkers search
for online. This methodology results in moderate inter-annotator agreement.
Furthermore, we use the retrieved evidence extracts as part of a fact-checking
pipeline, finding that the real-world evidence is more useful than the
knowledge indirectly available in pretrained language models.
