GolemPII-v1 - Hebrew PII Detection Model
This model is trained to detect personally identifiable information (PII) in Hebrew text. While based on the multilingual XLM-RoBERTa model, it has been specifically fine-tuned on Hebrew data to achieve high accuracy in identifying and classifying various types of PII.
Model Details
- Based on xlm-roberta-base
- Fine-tuned on the GolemGuard: Hebrew Privacy Information Detection Corpus
- Optimized for token classification tasks in Hebrew text
Intended Uses & Limitations
This model is intended for:
- Privacy Protection: Detecting and masking PII in Hebrew text to protect individual privacy.
- Data Anonymization: Automating the process of de-identifying Hebrew documents in legal, medical, and other sensitive contexts.
- Research: Supporting research in Hebrew natural language processing and PII detection.
Training Parameters
- Batch Size: 32
- Learning Rate: 2e-5 with linear warmup and decay.
- Optimizer: AdamW
- Hardware: Trained on a single NVIDIA A100GPU.

Model Architecture
The model is based on the FacebookAI/xlm-roberta-base
architecture, a transformer-based language model pre-trained on a massive multilingual dataset. No architectural modifications were made to the base model during fine-tuning.
Usage
import torch
from transformers import AutoTokenizer, AutoModelForTokenClassification
tokenizer = AutoTokenizer.from_pretrained("{repo_id}")
model = AutoModelForTokenClassification.from_pretrained("{repo_id}")
# Example text (Hebrew)
text = "שלום, שמי דוד כהן ואני גר ברחוב הרצל 42 בתל אביב. הטלפון שלי הוא 050-1234567"
# Tokenize and get predictions
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True)
with torch.no_grad():
outputs = model(**inputs)
predictions = torch.argmax(outputs.logits, dim=2)
# Convert predictions to labels
tokens = tokenizer.convert_ids_to_tokens(inputs["input_ids"][0])
labels = [model.config.id2label[t.item()] for t in predictions[0]]
# Print results (excluding special tokens and non-entity labels)
for token, label in zip(tokens, labels):
if label != "O" and not token.startswith("##"):
print(f"Token: {token}, Label: {label}")
