Guiding Text-to-Text Privatization by Syntax

no code implementations2 Jun 2023 Stefan Arnold, Dilara Yesilbas, Sven Weinzierl

Lacking the capability to produce surrogate texts that correlate with the structure of the sensitive texts, we encompass our analysis by transforming the privatization step into a candidate selection problem in which substitutions are directed to words with matching grammatical properties.
