This is a Named Entity Recognition model based on tanaos/tanaos-NER-v1 and fine-tuned on a synthetic dataset to recognize Personal Identifiable Information (PII) entities in text. Once identified, the entities are redacted to ensure privacy and confidentiality, before sharing or processing text data.

While the base NER model was trained to recognize 14 named entity categories, this Text Anonymization was fine-tuned specifically to focus on the following 5 key PII entity categories that are commonly found in text data and are critical for anonymization:

Entity	Description
`PERSON`	Individual people, fictional characters
`LOCATION`	Geographical areas
`DATE`	Absolute or relative dates, including years, months and/or days
`ADDRESS`	Full addresses
`PHONE_NUMBER`	Telephone numbers

How to Use

Use this model through the Artifex library:

install Artifex with

pip install artifex

use the model with

python

from artifex import Artifex

ta = Artifex().text_anonymization()

anonymized_text = ta("John Doe lives at 123 Main St, New York. His phone number is (555) 123-4567.")
print(anonymized_text)

# >>> ["[MASKED] lives at [MASKED]. His phone number is [MASKED]."]

Model Description

Base model: FacebookAI/roberta-base
Task: Token classification (Named Entity Recognition for Text Anonymization)
Languages: English
Fine-tuning data: A synthetic, custom dataset of around 10,000 passages, each containing multiple named entities across 5 Personal Identifiable Information categories.

Training Details

This model was trained using the Artifex Python library

pip install artifex

by providing the following instructions and generating 10,000 synthetic training samples:

python

from artifex import Artifex

ta = Artifex().text_anonymization()

ta.train(
    domain="general",
    num_samples=10000
)

Intended Uses

This model is intended to:

Anonymize text data by redacting personal identifiable information (PII) such as names, addresses, phone numbers, dates, and locations.
Ensure privacy and confidentiality in text data for compliance with data protection regulations.
Be used before sharing or processing text data to protect sensitive information.
Stay GDPR compliant when handling personal data.

Not intended for:

Scenarios involving highly specialized or domain-specific text without further fine-tuning.
