Measuring Fairness with Biased Rulers: A Comparative Study on Bias Metrics for Pre-trained Language Models

no code implementations NAACL 2022 Pieter Delobelle, Ewoenam Tokpo, Toon Calders, Bettina Berendt

We survey the literature on fairness metrics for pre-trained language models and experimentally evaluate compatibility, including both biases in language models and in their downstream tasks.

Addressing the Regulatory Gap: Moving Towards an EU AI Audit Ecosystem Beyond the AIA by Including Civil Society

no code implementations26 Feb 2024 David Hartmann, José Renato Laranjeira de Pereira, Chiara Streitbörger, Bettina Berendt

By considering the value of third-party audits and third-party data access in an audit ecosystem, we identify a regulatory gap in that the Artificial Intelligence Act does not provide access to data for researchers and civil society.

Domain Adaptive Decision Trees: Implications for Accuracy and Fairness

1 code implementation27 Feb 2023 Jose M. Alvarez, Kristen M. Scott, Salvatore Ruggieri, Bettina Berendt

In uses of pre-trained machine learning models, it is a known issue that the target population in which the model is being deployed may not have been reflected in the source population with which the model was trained.

How Far Can It Go?: On Intrinsic Gender Bias Mitigation for Text Classification

1 code implementation30 Jan 2023 Ewoenam Tokpo, Pieter Delobelle, Bettina Berendt, Toon Calders

Considering that the end use of these language models is for downstream tasks like text classification, it is important to understand how these intrinsic bias mitigation strategies actually translate to fairness in downstream tasks and the extent of this.

Political representation bias in DBpedia and Wikidata as a challenge for downstream processing

no code implementations29 Dec 2022 Ozgur Karadeniz, Bettina Berendt, Sercan Kiyak, Stefan Mertens, Leen d'Haenens

We describe a case study of the relative over- or under-representation of Belgian political parties between 1990 and 2020 in the English-language DBpedia, the Dutch-language DBpedia, and Wikidata, and highlight the many decisions needed with regard to the design of this data analysis and the assumptions behind it, as well as implications from the results.

RobBERT-2022: Updating a Dutch Language Model to Account for Evolving Language Use

no code implementations15 Nov 2022 Pieter Delobelle, Thomas Winters, Bettina Berendt

To evaluate if our new model is a plug-in replacement for RobBERT, we introduce two additional criteria based on concept drift of existing tokens and alignment for novel tokens. We found that for certain language tasks this update results in a significant performance increase.

FairDistillation: Mitigating Stereotyping in Language Models

1 code implementation10 Jul 2022 Pieter Delobelle, Bettina Berendt

Large pre-trained language models are successfully being used in a variety of tasks, across many languages.

RobBERTje: a Distilled Dutch BERT Model

no code implementations28 Apr 2022 Pieter Delobelle, Thomas Winters, Bettina Berendt

We found that the performance of the models using the shuffled versus non-shuffled datasets is similar for most tasks and that randomly merging subsequent sentences in a corpus creates models that train faster and perform better on tasks with long sequences.

Measuring Fairness with Biased Rulers: A Survey on Quantifying Biases in Pretrained Language Models

1 code implementation14 Dec 2021 Pieter Delobelle, Ewoenam Kwaku Tokpo, Toon Calders, Bettina Berendt

We survey the existing literature on fairness metrics for pretrained language models and experimentally evaluate compatibility, including both biases in language models as in their downstream tasks.

Whistleblower protection in the digital age -- why 'anonymous' is not enough. From technology to a wider view of governance

no code implementations4 Nov 2021 Bettina Berendt, Stefan Schiffner

When technology enters applications and processes with a long tradition of controversial societal debate, multi-faceted new ethical and legal questions arise.

Measuring Shifts in Attitudes Towards COVID-19 Measures in Belgium Using Multilingual BERT

1 code implementation20 Apr 2021 Kristen Scott, Pieter Delobelle, Bettina Berendt

We classify seven months' worth of Belgian COVID-related Tweets using multilingual BERT and relate them to their governments' COVID measures.

Computational Ad Hominem Detection

1 code implementation ACL 2019 Pieter Delobelle, Murilo Cunha, Eric Massip Cano, Jeroen Peperkamp, Bettina Berendt

Fallacies like the personal attack{---}also known as the ad hominem attack{---}are introduced in debates as an easy win, even though they provide no rhetorical contribution.
