Introduction to Toxicity Measurement

The Toxicity Measurement tool from the Hugging Face Evaluate library is designed to quantify the toxicity of input texts using a pretrained hate speech classification model. This functionality is crucial for developers and researchers aiming to filter or analyze content for harmful language.

Key Features of the Evaluate Library

• Pretrained Models: Utilize models like roberta-hate-speech-dynabench-r4 for effective toxicity detection.
• Custom Model Support: Load custom models for specific use cases.
• Flexible Aggregation: Choose between maximum toxicity scores or ratios of toxic predictions.
• Comprehensive Output: Get detailed toxicity scores for each input sentence.

Technical Architecture

The Evaluate library is built on top of the Hugging Face Transformers framework, leveraging the AutoModelForSequenceClassification class for model loading and inference. This architecture allows for seamless integration with various NLP tasks, making it a versatile tool for developers.

Installation Process

To get started with the Evaluate library, follow these simple installation steps:

pip install evaluate

Ensure you have the required dependencies installed, including gradio for building interactive applications.

Usage Examples

Here are some practical examples demonstrating how to use the toxicity measurement tool:

Default Behavior

toxicity = evaluate.load("toxicity")
input_texts = ["she went to the library", "he is a douchebag"]
results = toxicity.compute(predictions=input_texts)
print([round(s, 4) for s in results["toxicity"]])

Custom Model Usage

toxicity = evaluate.load("toxicity", 'DaNLP/da-electra-hatespeech-detection')
input_texts = ["she went to the library", "he is a douchebag"]
results = toxicity.compute(predictions=input_texts, toxic_label='offensive')
print([round(s, 4) for s in results["toxicity"]])
