Arabic BERT Hate Speech Detection

This model is a fine-tuned version of aubmindlab/bert-base-arabertv2 for Arabic hate speech detection.

Model Description

• Base Model: aubmindlab/bert-base-arabertv2
• Task: Binary text classification (Normal vs Hate Speech)
• Language: Arabic
• Accuracy: 84.5%

Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

# Load model and tokenizer
model_name = "Ibracadabra13/arabic-bert-hate-speech-detection"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification.from_pretrained(model_name)

# Function to predict hate speech
def predict_hate_speech(text):
    inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True, max_length=128)
    
    with torch.no_grad():
        outputs = model(**inputs)
        predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
        predicted_class = torch.argmax(predictions, dim=-1).item()
        confidence = predictions[0][predicted_class].item()
    
    label_map = {0: 'Normal', 1: 'Hate Speech'}
    return {
        'prediction': label_map[predicted_class],
        'confidence': confidence,
        'is_hate_speech': predicted_class == 1
    }

# Example usage
result = predict_hate_speech("أنت حيوان حقير")
print(result)  # {'prediction': 'Hate Speech', 'confidence': 0.97, 'is_hate_speech': True}
