# BART-ToSSimplify

This model is a fine-tuned version of [facebook/bart-large-cnn](https://huggingface.co/facebook/bart-large-cnn) on an unknown dataset.
It achieves the following results on the evaluation set:
- Loss: 0.3895
- Rouge1: 0.6186
- Rouge2: 0.4739
- Rougel: 0.5159
- Rougelsum: 0.5152
- Gen Len: 108.6354

## Model description

BART-ToSSimplify is designed to generate summaries of Terms of Service documents.

## Intended uses & limitations

Intended Uses:
- Generating simplified summaries of Terms of Service agreements.
- Automating the summarization of legal documents for quick comprehension.

Limitations:
- This model is specifically designed for the English language and cannot be applied to other languages.
- The quality of generated summaries may vary based on the complexity of the source text.

## Training and evaluation data

BART-ToSSimplify was trained on a dataset consisting of summaries of various Terms of Service agreements. The dataset was collected and preprocessed to create a training and evaluation split.

## Training procedure
