 ### Supported Tasks and Leaderboards
 
 - `Fill-Mask`
 - `Text Generation`
-- `other:Language-Modelling`: The dataset is suitable for training a model in Language Modelling, predicting the next 
-word in a given context. Success is measured by achieving a low perplexity score, indicating the model's proficiency 
-in accurately predicting subsequent words. [Perplexity](https://huggingface.co/spaces/evaluate-metric/perplexity)
-- `other:Masked-Language-Modelling`: The dataset is designed for training models in Masked Language Modelling. This task 
-involves predicting masked or hidden words within a sentence. Success is typically measured by achieving a high 
-performance score, such as accuracy or F1 score, on correctly predicting the masked tokens.

 ### Curation Rationale
 
-CATalog is mainly built on filtered, non-overlapping versions of [CommonCrawl](https://commoncrawl.org/) snapshots and a smaller set of manually scored corpora from specific sources. We use the CURATE pipeline, which combines exact deduplication, language identification, and scoring heuristics.
+CATalog is mainly built on filtered, non-overlapping versions of [CommonCrawl](https://commoncrawl.org/) snapshots and a smaller set of manually scored corpora from specific sources. We use the [CURATE](https://github.com/langtech-bsc/corpus-cleaner-v2) pipeline, which combines exact deduplication, language identification, and scoring heuristics.
 
 In the design of CATalog, we adhere to the following values:
 
-- (1) **Scale & Flexibility**. We intend to produce datasets that have a significant impact on the training of multilingual models in the range of 7B-180B parameters. Since Catalan is a medium-resource language and data acquisition is already a challenge, binary filtering will limit us in terms of the amount of data. By providing a score, we are able to easily filter the corpus according to any requirements.

By providing a score, we are able to easily filter the corpus according to our corpus according to our needs.
 - (2) **Neutral scoring**. As opposed to ML-based filtering, we can use simple rules and heuristics to avoid introducing further bias into the model ([Dodge et al., 2021](https://arxiv.org/abs/2104.08758); [Welbl et al., 2021](https://arxiv.org/abs/2109.07445)). We only use [FastText](https://fasttext.cc/docs/en/language-identification.html) to reject documents in other languages.
 
-During development, we performed comparative judgment experiments to evaluate the usefulness of the scoring from the CURATE pipeline, which appears in most documents in CATalog and is intended for further filtering and analysis. We found a moderate correlation between the score and the perceived quality of the text. Our main goal was to maximize the usability of the corpus without getting into a trade-off between quantity and quality.

 #### Initial Data Collection and Normalization

+We applied extensive data processing using our [CURATE](https://github.com/langtech-bsc/corpus-cleaner-v2) pipeline.
 
 We first filter documents by their language content using [FastText](https://fasttext.cc/docs/en/language-identification.html). Only documents with at least 50% of characters in Catalan are kept. We then perform exact document deduplication. After this stage, we score each document with a tested set of 8 heuristic evaluators, inspired from other web filterings and from our own creation.
