The Topic Confusion Task: A Novel Evaluation Scenario for Authorship Attribution (2021.findings-emnlp)
Copied to clipboard
| Challenge: | Autorship attribution is the problem of identifying the most plausible author of an anonymous text from a set of candidate authors. |
| Approach: | They propose a topic confusion task where they switch the author-topic configuration between training and testing sets and propose attribution errors that are caused by the topic shift and by the features’ inability to capture the writing styles. |
| Outcome: | The proposed task combines author-topic configuration with other features to lower topic confusion and higher attribution accuracy. |
A Multifaceted Framework to Evaluate Evasion, Content Preservation, and Misattribution in Authorship Obfuscation Techniques (2022.emnlp-main)
Copied to clipboard
| Challenge: | Authorship obfuscation techniques are often evaluated based on their ability to hide the author’s identity (evasion) while preserving the content of the original text. |
| Approach: | They propose to evaluate authorship obfuscation techniques on detection evasion and content preservation using competitive identification techniques in real-life scenarios. |
| Outcome: | The proposed method reveals key weaknesses in state-of-the-art obfuscation techniques and surprisingly competitive effectiveness from a back-translation baseline in all evaluation aspects. |
