SPRINT-PP achieved the strongest tested accuracy while remaining privacy-safe and storing no raw historical PII.

Research framework

A comparable path through privacy datasets

Privacy datasets move through preprocessing and shared PII labels before model training and named-entity recognition evaluation. Relationships: Privacy datasets to Preprocessing; Preprocessing to Shared PII labels; Shared PII labels to Model training; Model training to NER evaluation.

PII-aware NER evaluation

ASC-PIE evaluates named-entity recognition for personally identifiable information across privacy-focused datasets.

Research data pipeline

The ASC-PIE experiments prepare real and synthetic privacy datasets for NER training and evaluation.

PII label standardization

The research pipeline maps differing PII label schemes into a shared representation for comparison.

ASC-PIE experiment stack

ASC-PIE experiments use Python, PyTorch, Hugging Face Transformers, scikit-learn, and seqeval.
