ModerationBERT-ML-En

ModerationBERT-ML-En is a moderation model based on bert-base-multilingual-cased. This model is designed to perform text moderation tasks, specifically categorizing text into 18 different categories. It currently works only with English text.

Dataset

The model was trained and fine-tuned using the text-moderation-410K dataset. This dataset contains a wide variety of text samples labeled with different moderation categories.

Model Description

ModerationBERT-ML-En uses the BERT architecture to classify text into the following categories:

harassment
harassment_threatening
hate
hate_threatening
self_harm
self_harm_instructions
self_harm_intent
sexual
sexual_minors
violence
violence_graphic
self-harm
sexual/minors
hate/threatening
violence/graphic
self-harm/intent
self-harm/instructions
harassment/threatening

Training and Fine-Tuning

The model was trained using a 95% subset of the dataset for training and a 5% subset for evaluation. The training was performed in two stages:

Initial Training: The classifier layer was trained with frozen BERT layers.
Fine-Tuning: The top two layers of the BERT model were unfrozen and the entire model was fine-tuned.

Installation

To use ModerationBERT-ML-En, you will need to install the transformers library from Hugging Face and torch.

pip install transformers torch

Usage

Here is an example of how to use ModerationBERT-ML-En to predict the moderation categories for a given text:

python

import json
import torch
from transformers import BertTokenizer, BertForSequenceClassification

# Load the tokenizer and model
model_name = "ifmain/ModerationBERT-En-02"
tokenizer = BertTokenizer.from_pretrained(model_name)
model = BertForSequenceClassification.from_pretrained(model_name, num_labels=18)

# Device configuration
device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')
model.to(device)

def predict(text, model, tokenizer):
    encoding = tokenizer.encode_plus(
        text,
        add_special_tokens=True,
        max_length=128,
        return_token_type_ids=False,
        padding='max_length',
        truncation=True,
        return_attention_mask=True,
        return_tensors='pt'
    )
    input_ids = encoding['input_ids'].to(device)
    attention_mask = encoding['attention_mask'].to(device)
    model.eval()
    with torch.no_grad():
        outputs = model(input_ids, attention_mask=attention_mask)
    predictions = torch.sigmoid(outputs.logits)  # Convert logits to probabilities
    return predictions

# Example usage
new_text = "Fuck off stuped trash"
predictions = predict(new_text, model, tokenizer)

# Define the categories
categories = ['harassment', 'harassment_threatening', 'hate', 'hate_threatening', 
              'self_harm', 'self_harm_instructions', 'self_harm_intent', 'sexual', 
              'sexual_minors', 'violence', 'violence_graphic', 'self-harm', 
              'sexual/minors', 'hate/threatening', 'violence/graphic', 
              'self-harm/intent', 'self-harm/instructions', 'harassment/threatening']

# Convert predictions to a dictionary
category_scores = {categories[i]: predictions[0][i].item() for i in range(len(categories))}

output = {
    "text": new_text,
    "category_scores": category_scores
}

# Print the result as a JSON with indentation
print(json.dumps(output, indent=4, ensure_ascii=False))

Output:
