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. |

Neural Text Sanitization with Explicit Measures of Privacy Risk (2022.aacl-main)
Copied to clipboard
| Challenge: | Personal data, also known as Personally Identifiable Information (PII), often abound in text documents. |
| Approach: | They propose a method for text sanitization that uses a neural entity recognizer to detect and classify potential personal identifiers and a classifier trained on labelled data to determine which entities to mask . |
| Outcome: | The proposed approach masks all personal identifiers and thereby conceals the identity of the individuals mentioned in the document. |
STAMP: Selective Task-Aware Mechanism for Text Privacy (2026.eacl-long)
Copied to clipboard
| Challenge: | Experimental evaluations on SQuAD, Yelp, and AG News datasets demonstrate that STAMP achieves superior privacy–utility trade-offs across varying per-token privacy budgets. |
| Approach: | They propose a new framework for task-aware text privatization that selectively allocates privacy budgets across tokens by jointly considering (i) each token’s importance to the downstream task and (ii) its privacy sensitivity. |
| Outcome: | The proposed framework achieves superior privacy–utility trade-offs on SQuAD, Yelp, and AG News datasets. |
Deep Reinforcement Learning-based Text Anonymization against Private-Attribute Inference (D19-1)
Copied to clipboard
| Challenge: | Recent research shows textual data alone may contain enough information about users' private-attributes that they do not want to disclose such as age, gender, location, political views and sexual orientation. |
| Approach: | They propose a novel Reinforcement Learning-based Text Anonymizor which extracts a latent representation of the original text w.r.t. a given task and leverages deep reinforcement learning to learn an optimal strategy for manipulating text representations w/ the received privacy and utility feedback. |
| Outcome: | The proposed approach preserves both privacy and utility of textual data while preserving its utility. |
