# Kurdish Poetry Meter Classification

Multi-class **meter (prosody) classification** of **Central Kurdish** poetry for PoetryMTEB embedding evaluation.

Derived from the [VejinBooks Poem Dataset](https://github.com/AsoSoft/Vejinbooks-Poem-Dataset) (AsoSoft): expert-annotated meter and form tags for poems from [vejinbooks](https://books.vejin.net). Used in automatic Kurdish meter identification research ([Mahmudi & Veisi, PLOS ONE 2023](https://doi.org/10.1371/journal.pone.0280263)).

## Dataset Card

| Item | Description |
|------|-------------|
| **Dataset version (PoetryMTEB)** | `1.0.0` |
| **Source (GitHub)** | [AsoSoft/Vejinbooks-Poem-Dataset](https://github.com/AsoSoft/Vejinbooks-Poem-Dataset) |
| **Source (Zenodo)** | [https://doi.org/10.5281/zenodo.4079471](https://doi.org/10.5281/zenodo.4079471) |
| **Paper** | Mahmudi A, Veisi H. *Automatic meter classification of Kurdish poems*. *PLOS ONE*, 2023 ([DOI](https://doi.org/10.1371/journal.pone.0280263)) |
| **Languages** | Central Kurdish (`ckb`) |
| **Unit** | Full poem text (`poem`) |
| **Labels** | Single-label **15** meter patterns (`label` / `label_name`) |
| **Size** | train=624; validation=208; test=209; **total=1041** |
| **Splits** | Preserved from the previous PoetryMTEB release (~6:2:2 stratified by meter) |
| **License** | [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) (PoetryMTEB redistribution; cite original authors) |
| **Evaluation metrics** | Embedding classification: **accuracy**, **macro/micro F1** (see `scripts/evaluate_kurdish_meter.py`) |

> **Note on size:** Upstream VejinBooks release has **1154** poems. This packaging keeps **1041** poems after filtering to meters with **≥10** examples (and format checks), matching the prior PoetryMTEB release.

## Label taxonomy (15 meters)

| id | label_name (meter) | train | validation | test | total |
|---:|--------------------|------:|-----------:|-----:|------:|
| 0 | `مفاعیلن مفاعیلن مفاعیلن مفاعیلن` | 146 | 48 | 49 | 243 |
| 1 | `فاعلاتن فاعلاتن فاعلاتن فاعلن` | 132 | 44 | 44 | 220 |
| 2 | `مفاعیلن مفاعیلن فعولن` | 79 | 26 | 27 | 132 |
| 3 | `مفعولُ مفاعیلُ مفاعیلُ فعولن` | 69 | 23 | 24 | 116 |
| 4 | `فعلاتن فعلاتن فعلاتن فعلن` | 44 | 14 | 15 | 73 |
| 5 | `10Syllabic` | 27 | 9 | 10 | 46 |
| 6 | `FreeVerse` | 26 | 9 | 8 | 43 |
| 7 | `فاعلاتن فاعلاتن فاعلن` | 20 | 7 | 6 | 33 |
| 8 | `مفعولُ فاعلاتُ مفاعیلُ فاعلن` | 18 | 7 | 6 | 31 |
| 9 | `8Syllabic` | 18 | 6 | 6 | 30 |
| 10 | `فعلاتن مفاعلن فعلن` | 15 | 5 | 5 | 25 |
| 11 | `مفعولُ مفاعیلن مفعولُ مفاعیلن` | 10 | 3 | 3 | 16 |
| 12 | `فعلاتن فعلاتن فعلن` | 8 | 3 | 2 | 13 |
| 13 | `7Syllabic` | 6 | 2 | 2 | 10 |
| 14 | `مفعولُ فاعلاتن مفعولُ فاعلاتن` | 6 | 2 | 2 | 10 |

Codebook: `label_taxonomy.json`.

## Features

| Field | Type | Description |
|-------|------|-------------|
| `id` | string | Example id (`kpmc-{split}-{legacy_id}`) |
| `poet` | string | Poet name (from upstream filename, e.g. `Diɫdar`) |
| `poem_number` | string | Poem number within poet (e.g. `002`) |
| `title` | string | Poem title (often first hemistich) |
| `form` | string | Poetic form in Kurdish (e.g. غەزەل, مەسنەوی, نوێ) |
| `poem` | string | **Classification input**: poem body (`#` couplet markers removed; newlines kept) |
| `label` | int64 | Meter class id |
| `label_name` | string | Meter pattern string (formerly `meter`) |

Schema aligns with other PoetryMTEB classification datasets (`id`, `poem`, `label`, `label_name`).

## Construction method

1. Load existing `PoetryMTEB/KurdishPoetryMeterClassification` parquet splits.
2. Normalize fields: `text`→`poem`, `meter`→`label_name` + integer `label`.
3. Keep `poet`, `poem_number`, `title`, `form`; assign stable ids.
4. **Preserve train / validation / test** membership (no re-split in this packaging pass).
5. Write parquet + `dataset_infos.yaml` + Dataset Card + supporting materials.

### Upstream file format (reference)

```
title: ...
form: ...
meter: ...
<poem text from line 4>
```

- `#` marks a new couplet (stripped in this packaging).
- `++` marks non-Kurdish hemistiches in upstream files.
