Thunder-DeID: Accurate and Efficient De-identification Framework for Korean Court Judgments (2025.findings-emnlp)
Copied to clipboard
| Challenge: | a recent study shows that the current de-identification process is inadequate for court judgments at scale . |
| Approach: | They propose a framework for de-identification that aligns with relevant laws and practices . they construct and release the first Korean legal dataset containing annotated judgments . |
| Outcome: | The proposed framework achieves state-of-the-art in the de-identification of court judgments. |
Generalizing Clinical De-identification Models by Privacy-safe Data Augmentation using GPT-4 (2024.emnlp-main)
Copied to clipboard
| Challenge: | De-identification (de-ID) is critical for patient confidentiality in clinical data management due to the difficulty of retaining training corpora and labeling standards vary across institutions. |
| Approach: | They propose to exploit GPT-4 for data augmentation through one-shot and zero-shot prompts to exploit the problem of PHI leakage by redacting PHI before processing. |
| Outcome: | The proposed approach significantly improves on three types of F1 scores in cross-dataset testing. |
