 ## Dataset Description
 
-This dataset contains a specific snapshot of the sustainability procurement criteria catalogs available at [IntelliProcure/sustainability_criteria](https://huggingface.co/datasets/IntelliProcure/sustainability_criteria). This version was used to annotate Swiss calls for tender, which form the core of the [IntelliProcure/SwissSPARK](https://huggingface.co/datasets/IntelliProcure/SwissSPARK) dataset. Users working with [IntelliProcure/SwissSPARK](https://huggingface.co/datasets/IntelliProcure/SwissSPARK) are advised to use this specific catalog version to ensure consistency, as newer iterations may differ from those used in the original annotation.
+This dataset is designed to train and evaluate models for detecting sustainability criteria in Swiss public procurement documents (Call for Tenders, CFT). The dataset classifies text segments based on whether they contain specific sustainability requirements according to official Swiss guidelines.
