| # Pravda.sk URL-based Clustering Dataset | |
| A Slovak news article clustering dataset based on URL structure from [pravda.sk](https://pravda.sk), designed for evaluating text clustering and embedding models. | |
| ## Dataset Description | |
| This dataset contains 15,000 Slovak news articles categorized by their URL structure. Articles are organized into 50 categories across 11 subdomains, providing a hierarchical classification based on editorial decisions. | |
| ### Use Case | |
| This dataset is designed for: | |
| - Evaluating Slovak text embedding models | |
| - Clustering benchmark tasks (MTEB) | |
| - Text classification experiments | |
| - Slovak NLP research | |
