| ## Dataset Card for ViHOS |
|
|
| ### 1. Dataset Summary |
|
|
| **ViHOS** (Vietnamese Hate and Offensive Spans) is the first Vietnamese corpus with **span-level** annotations of hateful and offensive content. It contains **26,476** annotated spans over **11,056** comments: |
|
|
| * **5,360** comments containing ≥1 hate/offensive spans |
| * **5,696** clean comments (no spans) |
|
|
| Annotations cover a rich variety of phenomena (teencodes, metaphors, puns, etc.), with both span‑extraction and sequence‑labeling formats. |
|
|
| ### 2. Supported Tasks and Leaderboard |
|
|
| * **Primary Task**: Sequence labeling / span extraction for hate/offensive detection |
| * **Metrics**: Precision, recall, F1‑score on span detection |
|
|
| *No public leaderboard; share your results in the ViSoLex repo!* |

| | ------------- | -------- | --------------------------------------------------------------------------- | |
| | `sentence` | `string` | The raw Vietnamese comment. | |
| | `word` | `string` | Words in the sentence after the processing of tokenization using VnCoreNLP tokenizer | |
| | `index_spans` | `string` | JSON‑encoded list of indices (for span extraction) *or* list of BIO labels. | |
| | `tag` | `string` | The tag of the word. The tag is either B-T (beginning of a word), I-T (inside of a word), or O (outside of a word) | |
| | `type` | `string` | Split: `train` / `validation` / `test`. | |
|

|
|
| ### 5. Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| ds = load_dataset("visolex/ViHOS") |
| |
| train_ds = ds.filter(lambda x: x["type"] == "train") |
| dev_ds = ds.filter(lambda x: x["type"] == "dev") |
| test_ds = ds.filter(lambda x: x["type"] == "test") |
| |
| # Example |
| print(train_ds[0]) |
| ``` |
