+# Multilingual Poetry Meter Classification
+
+Multilingual **metrical foot classification** for PoetryMTEB embedding evaluation, built from EN/DE/ES/CS corpora with full text in [multilingual-annotated-poems](https://github.com/riazhsks/multilingual-annotated-poems).
+
+Hungarian and modern Czech (C3P) standalone annotation files are excluded (no poem text in-repo).

+| Item | Description |
+|------|-------------|
+| **Source** | [https://github.com/riazhsks/multilingual-annotated-poems](https://github.com/riazhsks/multilingual-annotated-poems) English / German / Spanish / CCV JSONL |
+| **Languages** | `en`, `de`, `es`, `cs` |
+| **Size** | train=24464; test=6114 (no validation) |
+| **Classes** | 7 meters with frequency ≥ 10 (after per-language cap) |
+| **Filtering** | Valid `metrical_foot`; drop noisy tags (`s`/`c`/`single`/…); length ∈ [40, 8000]; ≤10000 poems / language (stratified by meter) |
+| **Splits** | Stratified by `language×meter` ≈ 80% / 19%, seed=42 |

+
+## Construction method
+
+1. Load EN/DE/ES/CCV JSONL with `text` + `metrical_foot`.
+2. Normalize meters; drop invalid/noisy tags; length-filter.
+3. Cap each language at 10000 (stratified by meter) for balance.
+4. Keep meters with ≥ 10 examples; assign frequency-descending ids.
+5. Stratified train/test by language×meter.
+
+## How to load
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("PoetryMTEB/MultilingualPoetryMeterClassification")
+print(ds["test"][0]["language"], ds["test"][0]["label_name"])
+```
+
