⚙️ Usage

Installation

pip install transformers torch

Single Prediction

from transformers import pipeline

classifier = pipeline(
    task="text-classification",
    model="nahiar/hatespeech-abusive-xlm-roberta-v1",
    return_all_scores=True
)

result = classifier("Dasar bodoh, otak udang!")
print(result)

Output

[
  {'label': 'HATESPEECH', 'score': 0.9123},
  {'label': 'ABUSIVE', 'score': 0.9841}
]

Because this is a multilabel model, more than one label can be active for a single input.

🏷️ Label Definitions

HATESPEECH → Content that attacks or demeans a group based on identity
ABUSIVE    → Insulting, offensive, or aggressive language without protected targets

📦 Batch Inference

texts = [
    "Dasar kaum ini selalu bikin rusuh",
    "Kamu memang bodoh dan tidak berguna",
    "Saya tidak setuju dengan pendapat kamu"
]

results = classifier(texts)

for text, preds in zip(texts, results):
    labels = [(p["label"], round(p["score"], 4)) for p in preds]
    print(text, "→", labels)
