Construction method

1. Load SAHITTO.ods (sheet Poems: title, poem, writer, label).
2. Keep all 11 category labels; map to contiguous label ids (frequency-descending).
3. Stratified train / validation / test split by category (each class appears in all three splits).

---

How to load

from datasets import load_dataset

ds = load_dataset("PoetryMTEB/SahittoCategoryClassification")
print(ds["test"][0]["label_name"], ds["test"][0]["title"])

For embedding evaluation, encode poem (optionally prepend title), fit a classifier on train, optionally tune on validation, score on test.
