## Dataset Card for ViSoLex‑HSD

### 1. Dataset Summary

**ViSoLex‑HSD** is a unified Vietnamese hate‐speech detection corpus, combining three benchmark datasets:

* **ViHSD** (Son et al., 2021): 33K comments labeled **CLEAN**, **OFFENSIVE**, or **HATE** 
* **UIT‑ViCTSD** (Nguyen et al., 2020): 10K comments annotated for **TOXIC** (mapped to **HATE**) or **CLEAN** 
* **ViHOS** (Hoang et al., 2023): span‐level labels aggregated into comment‐level **HATE**/**CLEAN** 

After renaming and mapping labels (0 = CLEAN; 1 = OFFENSIVE; 2 = HATE) and concatenating - with duplicate comments removed - the final DataFrame contains:

* **Columns**:

  * `dataset`: original source (`ViHSD`/`ViCTSD`/`ViHOS`)
  * `type`: split indicator (`train`/`validation`/`test`)
  * `comment`: raw text
  * `label`: numeric (0/1/2)


### 2. Supported Tasks and Metrics

* **Task**: Text classification – Hate speech detection
* **Labels**:

  * 0 → CLEAN (no offensive content)
  * 1 → OFFENSIVE (non‐hate offensive language)
  * 2 → HATE (hate speech)
* **Metrics**: Accuracy, Precision/Recall/F1 per class


### 3. Languages

* Vietnamese


### 4. Dataset Structure

| Column    | Type   | Description                            |
| --------- | ------ | -------------------------------------- |
| `dataset` | string | Origin: `ViHSD` / `ViCTSD` / `ViHOS`   |
| `type`    | string | Split: `train` / `validation` / `test` |
| `comment` | string | The social‐media comment in Vietnamese |
| `label`   | int    | 0=CLEAN, 1=OFFENSIVE, 2=HATE           |


### 6. Usage

```python
from datasets import load_dataset

ds = load_dataset("your-namespace/visolex-hsd")

train_ds = ds.filter(lambda x: x["type"] == "train")
val_ds   = ds.filter(lambda x: x["type"] == "dev")
test_ds  = ds.filter(lambda x: x["type"] == "test")

print(train_ds.features)
print(train_ds[0])
```

### 7. Dataset Creation & Processing

1. **Load original CSVs** for ViHSD, ViCTSD, ViHOS.
2. **Rename columns** to `comment` and `label`.
3. **Map labels**:

   * ViHSD: keep 0/1/2.
   * ViCTSD: map `Toxicity` 1→2, 0→0.
   * ViHOS: span‐exists→2, no span→0.
4. **Concatenate**, retain only `dataset`, `type`, `comment`, `label`.
5. **Drop duplicates** on `comment`.
