FairBelief - Assessing Harmful Beliefs in Language Models

no code implementations27 Feb 2024 Mattia Setzu, Marta Marchiori Manerba, Pasquale Minervini, Debora Nozza

Language Models (LMs) have been shown to inherit undesired biases that might hurt minorities and underrepresented groups if such systems were integrated into real-world applications without careful fairness auditing.

Weigh Your Own Words: Improving Hate Speech Counter Narrative Generation via Attention Regularization

1 code implementation5 Sep 2023 Helena Bonaldi, Giuseppe Attanasio, Debora Nozza, Marco Guerini

Regularized models produce better counter narratives than state-of-the-art approaches in most cases, both in terms of automatic metrics and human evaluation, especially when hateful targets are not present in the training data.

What about em? How Commercial Machine Translation Fails to Handle (Neo-)Pronouns

no code implementations25 May 2023 Anne Lauscher, Debora Nozza, Archie Crowley, Ehm Miltersen, Dirk Hovy

As 3rd-person pronoun usage shifts to include novel forms, e. g., neopronouns, we need more research on identity-inclusive NLP.

Measuring Harmful Representations in Scandinavian Language Models

1 code implementation21 Nov 2022 Samia Touileb, Debora Nozza

Scandinavian countries are perceived as role-models when it comes to gender equality.

Easily Accessible Text-to-Image Generation Amplifies Demographic Stereotypes at Large Scale

1 code implementation7 Nov 2022 Federico Bianchi, Pratyusha Kalluri, Esin Durmus, Faisal Ladhak, Myra Cheng, Debora Nozza, Tatsunori Hashimoto, Dan Jurafsky, James Zou, Aylin Caliskan

For example, we find cases of prompting for basic traits or social roles resulting in images reinforcing whiteness as ideal, prompting for occupations resulting in amplification of racial and gender disparities, and prompting for objects resulting in reification of American norms.

Data-Efficient Strategies for Expanding Hate Speech Detection into Under-Resourced Languages

1 code implementation20 Oct 2022 Paul Röttger, Debora Nozza, Federico Bianchi, Dirk Hovy

More data is needed, but annotating hateful content is expensive, time-consuming and potentially harmful to annotators.

The State of Profanity Obfuscation in Natural Language Processing

1 code implementation14 Oct 2022 Debora Nozza, Dirk Hovy

Work on hate speech has made the consideration of rude and harmful examples in scientific publications inevitable.

Is It Worth the (Environmental) Cost? Limited Evidence for Temporal Adaptation via Continuous Training

no code implementations13 Oct 2022 Giuseppe Attanasio, Debora Nozza, Federico Bianchi, Dirk Hovy

Consequently, we should continuously update our models with new data to expose them to new events and facts.

ferret: a Framework for Benchmarking Explainers on Transformers

1 code implementation2 Aug 2022 Giuseppe Attanasio, Eliana Pastor, Chiara Di Bonaventura, Debora Nozza

With ferret, users can visualize and compare transformers-based models output explanations using state-of-the-art XAI methods on any free-text or existing XAI corpora.

Language Invariant Properties in Natural Language Processing

1 code implementation nlppower (ACL) 2022 Federico Bianchi, Debora Nozza, Dirk Hovy

We introduce language invariant properties: i. e., properties that should not change when we transform text, and how they can be used to quantitatively evaluate the robustness of transformation algorithms.
