Tasks:
We invite you to take part in the CLEF-2020 CheckThat! Lab on Automatic
Identification and Verification of Claims in Social Media. Three tasks are
available in English, one of which features a dataset about COVID-19:

Task 1: Check-Worthiness on Tweets. The task asks to rank a stream of tweets
on a number of topics, including COVID-19, according to their
check-worthiness.  (https://github.com/sshaar/clef2020-factchecking-task1). 

Task 2: Verified Claim Retrieval. Given a check-worthy claim and a set of
verified claims, rank the verified claims, so that those that verify the input
claim (or a sub-claim in it) are ranked on top
(https://github.com/sshaar/clef2020-factchecking-task2). 

Task 5: Check-Worthiness on Debates. Given a debate segmented into sentences,
together with speaker information, prioritize sentences for fact-checking
(https://github.com/sshaar/clef2020-factchecking-task5). 

The CheckThat! Lab also has three tasks in Arabic (check the Lab website for
details). 
The Lab will be held in conjunction with CLEF 2020, which will be an online
event.
