emiemimi/privacy-filter-multilingual-500

Multilingual Fine-Tuned Privacy Filter

This model is a fine-tuned version of openai/privacy-filter for multilingual PII token classification.

https://huggingface.co/emiemimi/privacy-filter-multilingual-500

Training Data

• Dataset: ai4privacy/pii-masking-openpii-1m
• Languages: English, Polish, Swedish, German, French, Spanish
• Training setting: 500 examples per language
• Base model: openai/privacy-filter

OpenPII labels were mapped to the output label set used by openai/privacy-filter, including person, email, phone, date, address, account number, and secret categories.

Evaluation

The retained final evaluation uses the shared 50 examples per language, 300 rows total.

simple counts a prediction as correct when it overlaps a gold PII span. improved also requires the mapped PII category to match.

Usage

from transformers import AutoModelForTokenClassification, AutoTokenizer

model_id = "emiemimi/privacy-filter-multilingual-500"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForTokenClassification.from_pretrained(model_id)
