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

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.
