Design and Evaluation of a Post-NER Refinement Pipeline for Clinical Note De-identification

This project presents a transparent, locally deployable post-NER de-identification framework that augments NER-based extraction with two refinement stages: a Verification loop for correcting candidate entities and a Candidate Expansion loop for recovering missed protected health information (PHI).

Improving Clinical Note De-identification via Post-NER Verification and Candidate Expansion

De-identification of clinical notes is critical for protecting patient privacy, yet existing approaches often struggle under real-world variation and provide limited support for auditing and error analysis. By examining the outputs of NER-based systems, we observe three recurring failure modes—false positives, false ne...
