# FannOrFlopClassification

Single-label **Arabic poetry classification** for PoetryMTEB embedding evaluation, derived from [Fann or Flop](https://huggingface.co/datasets/omkarthawakar/FannOrFlop) (EMNLP 2025).

Three configs share the **same poems and the same poet-aware train/validation/test split**:

| Config | Task | #classes |
|--------|------|---------:|
| `genre` | poetic genre / theme | 14 |
| `meter` | poetic meter (ʿarūḍ) | 19 |
| `era` | historical era | 12 |

## Dataset Card

| Item | Description |
|------|-------------|
| **Source** | [omkarthawakar/FannOrFlop](https://huggingface.co/datasets/omkarthawakar/FannOrFlop); paper [arXiv:2505.18152](https://arxiv.org/abs/2505.18152) |
| **Languages** | Arabic (`ar`) |
| **Size** | train=5176; validation=657; test=1106 (after filtering) |
| **Filtering** | Removed poems with unlabeled meter `غير محدد` (n=45). Raw=6984 → kept=6939. |
| **Label type** | Single-label multiclass (`label` int + `label_name` string) |
| **Splits** | Poet-aware ~8:1:1 (`train` / `validation` / `test`), **shared across configs** |
| **License** | [Apache-2.0](https://www.apache.org/licenses/LICENSE-2.0) (same as upstream) |
| **Evaluation metrics** | Classification on embeddings: **accuracy**, **macro/weighted F1** |

## Construction method

1. Load [omkarthawakar/FannOrFlop](https://huggingface.co/datasets/omkarthawakar/FannOrFlop).
2. Drop poems whose `meter` is `غير محدد` (unlabeled).
3. Normalize `poem_verses` into `poem` (strip numeric verse indices).
4. Build frequency-ordered label vocabularies for `genre`, `meter`, `era`.
5. Poet-aware split ≈ 80% / 10% / 10%; reuse the same split for all three configs.

---

## How to load

```python
from datasets import load_dataset

genre = load_dataset("PoetryMTEB/FannOrFlopClassification", "genre")
meter = load_dataset("PoetryMTEB/FannOrFlopClassification", "meter")
era = load_dataset("PoetryMTEB/FannOrFlopClassification", "era")

print(genre["test"][0]["title"], genre["test"][0]["label_name"])
```

For embedding evaluation, encode `poem` (optionally prepend `title`), then train a linear / MLP classifier on `label`.
