Tau-Eval: A Unified Evaluation Framework for Useful and Private Text Anonymization (2025.emnlp-demos)
Copied to clipboard
| Challenge: | Existing studies on text anonymization prioritize privacy preservation at the expense of utility, relying on reference-based metrics like ROUGE, BERTScore, or METEOR to measure textual fidelity. |
| Approach: | They propose an open-source framework for benchmarking text anonymization methods through the lens of privacy and utility task sensitivity. |
| Outcome: | The proposed framework is open-source and provides a Python library, documentation and tutorials. |
Adaptive Text Anonymization: Learning Privacy-Utility Trade-offs via Prompt Optimization (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing methods for anonymizing textual documents lack flexibility to adapt to diverse requirements. |
| Approach: | They propose a task formulation in which anonymization strategies are automatically adapted to specific privacy–utility requirements. |
| Outcome: | The proposed framework achieves better privacy–utility trade-off than existing baselines on open-source language models while remaining computationally efficient and effective on larger closed-source models. |
