Base model

This model is based on distilroberta-base.

Examples

The model has an accuracy score of ~96% (0.961206).
Here are a few examples:

Test with name, email and phone

plaintext

Original: My name is John Doe. Email: john@example.com. Phone: +49 123 45678.
Protected: My name is [PERSON]. Email: [EMAIL]. Phone: [PHONE].

Basic test

plaintext

Original: I live in Cambridge
Protected: I live in [ADDRESS]

French test (multilingual)

plaintext

Original: Mon e-mail est jean.dupont@example.fr et mon téléphone est +33 6 12 34 56 78.
Protected: Mon e-mail est [EMAIL] et mon téléphone est [PHONE].

Quickstart

To use this model, just download use.py from this repo and launch it:

bash

mkdir Shield-82M
cd Shield-82M
wget https://huggingface.co/LH-Tech-AI/Shield-82M/resolve/main/use.py
python3 use.py

This outputs something like:

Original: My name is John Doe. Email: john@example.com. Phone: +49 123 45678.
Protected: My name is [PERSON]. Email: [EMAIL]. Phone: [PHONE].

To use it with your own text, you'll have to adjust this line of code in use.py:

sample = "My name is John Doe. Email: john@example.com. Phone: +49 123 45678."
