CheckThat Lab Task 2 on Claim Normalization Monolingual

This tasks addresses the growing need to extract verified claims from the informal language found on social media. Unlike standard fact-checking pipelines that rely on well-formed input, our task aimed to rewrite user-generated content --often imprecise, opinionated, or fragmented-- into clear, concise, and factual statements, the way that human fact-checkers formulate the claims they are checking. The monolingual track covered thirteen languages, including English, German, French, Spanish, Portugese, Hindi, Marathi, Punjabi, Tamil, Arabic, Thai, Indonesian, and Polish.
