| ### 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. | |

| ## 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. | |
