(apologies for cross-posting) Dear colleague, We invite you to participate in the 2026 edition of the CheckThat! Lab at CLEF 2026. This year, we feature three tasks ---two follow-up and one new--- that correspond to important components within and around the full fact-checking pipeline in multiple languages: Task 1 Source Retrieval for Scientific Web Claims: Given a social media post that contains a scientific claim and an implicit reference to a scientific paper (mentions it without a URL), retrieve the mentioned paper from a pool of candidate papers. Available in English, German, and French. Task 2 Fact-Checking Numerical Claims:Given claims, potential evidence, and possible reasoning paths, rank the reasoning paths and provide an output of verdict. Available in Arabic, English, and Spanish. Task 3 Generating Full Fact-Checking Articles:Given a claim, its veracity, and a set of evidence documents consulted for fact-checking the claim, generate a full fact-checking article.
