# WikiCAT\_ca: Catalan Text Classification Dataset

## Dataset Description

* **Homepage:** [Projecte AINA](https://projecteaina.cat/tech/)
* **Repository (HF):** [huggingface.co/projecte-aina](https://huggingface.co/projecte-aina)
* **Repository (GitHub):** [TeMU-BSC/WikiCAT](https://github.com/TeMU-BSC/WikiCAT)
* **Point of Contact:** [langtech@bsc.es](mailto:langtech@bsc.es)

### Dataset Summary

WikiCAT\_ca is a Catalan corpus for thematic text classification tasks. It is automatically generated from Wikipedia and Wikidata sources, and contains **13,201 articles** from the Viquipèdia classified under **13 different categories**.

The dataset was developed by the **Text Mining Unit (TeMU) at the Barcelona Supercomputing Center (BSC)** within the framework of **Projecte AINA**. It is intended as an evaluation resource for language technologies applied to Catalan.

### Supported Tasks and Leaderboards

* Text classification (multi-class)
* Evaluation for Catalan language models

### Languages

* **Catalan (ca-ES)**

## Dataset Structure

### Data Instances

Each instance consists of an article text and its associated thematic label.

Example:

```json
{
  "sentence": "Celsius és conegut com l'inventor de l'escala centesimal del termòmetre...",
  "label": "Ciència"
}
```

### Data Fields

* **sentence**: `string` — text extracted from a Wikipedia article.
* **label**: `string` — one of 13 thematic categories.

### Labels

* Ciència\_i\_Tecnologia
* Dret
* Economia
* Enginyeria
* Entreteniment
* Esport
* Filosofia
* Història
* Humanitats
* Matemàtiques
* Música
* Política
* Religió

### Data Splits

* **train\_ca.json**: 9,907 label-document pairs
* **dev\_ca.json**: 2,484 label-document pairs

## Dataset Creation

### Curation Rationale

The dataset was created to provide a freely available resource for Catalan, a low-resource language, supporting the development of classification models.

### Source Data

* **Collection:** Pages were selected from thematic categories in Wikipedia (Catalan edition), including main pages, subcategories, and individual articles.
* **Text extraction:** The article summaries were used as representative text.

### Annotations

* **Process:** Automatic annotation based on Wikipedia categories.
* **Annotators:** N/A (fully automated).

### Personal and Sensitive Information

The dataset does not contain personal or sensitive information.

## Considerations for Using the Data

### Social Impact

This corpus supports the development of NLP resources for Catalan, helping reduce the resource gap for minority languages.

### Bias and Limitations

* Thematic coverage is dependent on Wikipedia categories, which may introduce systemic biases.
* No steps were applied to mitigate potential biases.
* Some categories may be underrepresented compared to others.
