+# 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
+
+## Dataset Structure
+
+### Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `url` | string | Original article URL |
+| `title` | string | Article headline |
