Participate in CLEF-2025 CheckThat! Lab
Participate in the 2025 edition of the CheckThat! Lab at CLEF 2025 and contribute to the development of fact-checking technologies.
We invite you to participate in the 2025 edition of the CheckThat! Lab at CLEF 2025.
This year, we feature four tasks that correspond to important components within and around the full fact-checking pipeline in multiple languages:
- Task 1: Subjectivity in news articles to spot text that should be processed with specific strategies.
- Task 2: Claim Normalization to simplify the primary claim made in the social media post into a concise form.
- Task 3: Fact-Checking Numerical Claims to verify claims with numerical quantities and temporal expressions.
- Task 4: Scientific Web Discourse Processing (SciWeb) to classify different forms of science-related online discourse and retrieve the scientific paper that serves as the source for the claim.
