People Make Better Edits: Measuring the Efficacy of LLM-Generated Counterfactually Augmented Data for Harmful Language Detection

1 code implementation2 Nov 2023 Indira Sen, Dennis Assenmacher, Mattia Samory, Isabelle Augenstein, Wil van der Aalst, Claudia Wagner

CADs introduce minimal changes to existing training data points and flip their labels; training on them may reduce model dependency on spurious features.

Counterfactually Augmented Data and Unintended Bias: The Case of Sexism and Hate Speech Detection

no code implementations NAACL 2022 Indira Sen, Mattia Samory, Claudia Wagner, Isabelle Augenstein

Especially, construct-driven CAD -- perturbations of core features -- may induce models to ignore the context in which core features are used.

Hate Speech Detection

Pathways through Conspiracy: The Evolution of Conspiracy Radicalization through Engagement in Online Conspiracy Discussions

"Call me sexist, but...": Revisiting Sexism Detection Using Psychological Scales and Adversarial Samples

1 code implementation27 Apr 2020 Mattia Samory, Indira Sen, Julian Kohne, Fabian Floeck, Claudia Wagner

By providing a scale-based codebook and insights regarding the shortcomings of the state-of-the-art, we hope to contribute to the development of better and broader models for sexism detection, including reflections on theory-driven approaches to data collection.
