# GolemGuard: Hebrew Privacy Information Detection Corpus

GolemGuard is a comprehensive Hebrew language dataset specifically designed for training and evaluating models for Personal Identifiable Information (PII) detection and masking. The dataset contains ~600MB of synthetic text data representing various document types and communication formats commonly found in Israeli professional and administrative contexts.

## Source Data
### Initial Data Collection and Normalization

The dataset combines synthetic data generated from multiple authoritative sources:

1. Names:
   - Israeli government open data portal (data.gov.il) for first names
   - Hebrew Wikipedia category for family names
   - Faker library
   - Additional curated sources

2. Addresses:
   - Israeli government datasets for cities
   - Israeli government street names datasets
   
3. Synthetic Identifiers:
   - ID numbers: Generated following Israeli ID number format and checksum rules
   - Bank accounts: Generated following Israeli bank account number formats
   - Postal codes: Based on valid Israeli postal code ranges
   - Credit cards: Generated following valid card number algorithms
   - Email addresses: Constructed using collected names and top Israeli email providers

## Considerations for Using the Data

### Social Impact of Dataset

The dataset aims to improve privacy protection in Hebrew text processing by enabling better PII detection and masking. This has important applications in:

| Application Area | Description |
|-----------------|-------------|
| Regulatory Compliance | Support for GDPR and PPLA requirements |
| Document Processing | Privacy-preserving text analysis and storage |
| Information Security | Automated PII detection and protection |
| Data Loss Prevention | Real-time PII identification and masking |

### Discussion of Biases

1. Geographic Bias
   - Dataset focuses on Israeli context and formats   

2. Name Distribution
   - While effort was made to include diverse names, distribution may not perfectly match population demographics


## Additional Information

### Dataset Curators

Dataset was generated by [Liran Baba](https://huggingface.co/CordwainerSmith).


### Model Training

Dataset was generated for training the [GolemPII-xlm-roberta-v1][model-link] model by Liran Baba (CordwainerSmith), model, demonstrating its effectiveness for PII detection and masking tasks in Hebrew text.

### Recommended Uses

| Use Case | Description |
|----------|-------------|
| Privacy Protection | Identifying and masking PII in Hebrew documents |
| Compliance Checking | Automated PII detection for regulatory compliance |
| Data Sanitization | Cleaning sensitive information from text data |
| Information Security | Supporting data loss prevention systems |
