+# PoetryFoundationSubjectsClassification
+
+Multi-label **poetry subject / theme classification** dataset for PoetryMTEB embedding evaluation, derived from Poetry Foundation poem subjects.
+
+## Dataset Card
+
+| Item | Description |
+|------|-------------|
+| **Source** | [suayptalha/Poetry-Foundation-Poems](https://huggingface.co/datasets/suayptalha/Poetry-Foundation-Poems); subject taxonomy aligned with [Poetry Foundation Topics](https://www.poetryfoundation.org/topics) |
+| **Languages** | English (`en`) |
+| **Size** | train=10259; validation=1283; test=1283 (poems with ≥1 mapped subject) |
+| **Label type** | Multi-label subjects at two granularities: L1 (coarse) and L2 (fine), with hierarchical codes |
+| **Splits** | Poet-aware ~8:1:1 split (`train` / `validation` / `test`) |
+| **Construction** | Parse original `Tags` → exclude occasions/holidays & emotion-like tags → alias to official subject names → assign `S{i}` / `S{i}-{j}` codes |
+| **License** | [GNU Affero General Public License v3.0](https://www.gnu.org/licenses/agpl-3.0.html) (same family as the upstream HF dataset) |
+| **Evaluation metrics** | Multi-label classification on embeddings: **macro/micro F1**, **Average Precision (AP)**; evaluate **L1 and L2 separately** |
+
+---
+
+## Features
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `id` | string | Example id |
+| `title` | string | Poem title |
+| `author` | string | Poet name |
+| `poem` | string | Poem body |
+| `labels_l1` | list[string] | Coarse subject codes, e.g. `S1`, `S6` |
+| `labels_l2` | list[string] | Fine subject codes with parent index, e.g. `S1-8`, `S6-6` |
+| `labels_l1_names` | list[string] | Human-readable L1 names |
+| `labels_l2_names` | list[string] | Human-readable paths `Parent/Child` |
+
+Full codebook: `label_taxonomy.json`.
+
+### L1 codes
+
+| Code | Subject |
+|------|---------|
+| `S1` | Love |
+| `S2` | Nature |
+| `S3` | Social Commentaries |
+| `S4` | History & Politics |
+| `S5` | Religion |
+| `S6` | Living |
+| `S7` | Time & Brevity |
+| `S8` | Relationships |
+| `S9` | Activities |
+| `S10` | Arts & Sciences |
+| `S11` | Mythology & Folklore |
+
+L2 codes are `S{i}-{j}` where `j` is the child index under that L1 (see taxonomy file). Example: `Living/Health & Illness` → `S6-6` (index depends on Living child order).
+
+---
+
+## Construction method
+
+1. **Upstream text & tags** from [suayptalha/Poetry-Foundation-Poems](https://huggingface.co/datasets/suayptalha/Poetry-Foundation-Poems) (`Title`, `Poet`, `Poem`, `Tags`).
+2. **Taxonomy** follows Poetry Foundation [Topics / Subjects](https://www.poetryfoundation.org/topics), with project adjustments:
+   - Occasions/holidays excluded
+   - Emotion-like `The Mind` / `Horror` excluded from subject labels
+   - `Health & Illness` placed under **Living**
+   - Dataset aliases (e.g. `Death`→`Death & Dying`, `First Love`→`New Love`)
+   - `Classic Love` kept as a Love L2 leaf
+3. **Hierarchical codes**: L1=`S{i}`; L2=`S{i}-{j}` (parent index explicit in the L2 code).
+4. **Split**: group by author, then allocate poet groups to train/validation/test ≈ 80%/10%/10%.
+
+---
+
+## Label statistics (all splits pooled)
+
+| Level | #label types | notes |
+|-------|-------------:|-------|
+| L1 | 11 | codes in use |
+| L2 | 71 | codes in use |
+| Avg L1 / poem | 2.55 | |
+| Avg L2 / poem | 2.27 | |
+
+---
+
+## How to load
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("PoetryMTEB/PoetryFoundationSubjectsClassification")
+print(ds["test"][0]["title"], ds["test"][0]["labels_l1"], ds["test"][0]["labels_l2_names"])
+```
+
+For embedding evaluation, encode `poem` (optionally prepend `title`), then train multi-label classifiers separately on `labels_l1` and `labels_l2`.
