-------- 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 in Thessaloniki, Greece.
