This volume contains the papers presented at the 3rd European Workshop on Algorithmic Fairness (EWAF’24) held on July 1-3, 2024 in Mainz, Germany. The purpose of the EWAF workshop series is to provide a venue for research and multidisciplinary dialogue between researchers working on algorithmic fairness in the context of Europe’s legal and societal framework, especially in light of the European Union’s attempts to promote ethical AI. The contributions to EWAF’24 mainly address the following topics: ● Empirical and theoretical perspectives from social sciences on fairness and discrimination in Europe (e.g., analysis of labor markets, the concept of class or race, discrimination against minorities in different social contexts). ● Case studies based on concrete European instances of algorithmic design and regulation that machine learning scholars have encountered in their own work (e.g., datasets or audits of automated decision-making systems that are used in Europe). ● Analysis of the implications of the European legislative framework for the debate on fairness in machine learning and AI more broadly (e.g., specificities connected to anti-discrimination and data collection legislation and the emerging regulatory frameworks for platforms and AI). ● Philosophy (e.g., values embedded in distributive and procedural fairness, foundations of ethical AI, critical studies on AI) ● Social Sciences (e.g., AI-based social assessment technologies, historical perspectives on discrimination, impact of algorithms on marginalized groups, perceptions of (un)fairness, AI and labor, digital governance, management and fairness) ● Policy and Law (e.g., non-discrimination law, data protection law and data governance, impact assessments, accountability measures, sensitive application areas of AI (e.g., the judiciary, government, law enforcement), global regulatory developments) We received 65 submissions of original papers presenting novel research results as well as extended abstracts containing descriptions of ongoing projects or summarizing already published results. The Program Committee (PC) was divided into four areas, i.e. Computer Science, Law and Policy, Philosophy, and Social Sciences. Each submission was reviewed by at least two PC members and one Area Chair. The reviewers evaluated each paper in terms of novelty, technical quality, clarity of presentation, potential impact, and European specificity. Finally, the scientific committee decided to accept 46 papers for presentation at the workshop and subsequent publication. EWAF’24 also had the pleasure to host four keynote talks by esteemed researchers in the topic of algorithmic fairness: CEUR ceur-ws.org Workshop ISSN 1613-0073 Proceedings ● Bettina Berendt, Professor at Technical University of Berlin, Weizenbaum Institute, and KU Leuven. “De-biased, diverse, divisive - On ethical perspectives regarding the de-biasing of GenAI and their actionability” ● Virginia Dignum, Professor at Umeå University. “Beyond the AI hype: Balancing Innovation and Social Responsibility” ● Isabel Valera, Professor at Saarland University. “Society-centered AI: An Integrative Perspective on Algorithmic Fairness” ● Seth Lazar, Professor at Australian National University (online). “What, if anything, should we do, now, about catastrophic AI risk?” Interactive sessions were also an important part of the EWAF’24 scientific program. We would like to thank the following organizers alongside Lorenzo Porcaro (Joint Research Centre - JRC) who reviewed the proposals: ● Thea Radüntz, Martin Brenzke and Dominik Köhler. “Striving for Equity: Navigating Algorithmic Fairness for AI in the Workplace” ● Marilisa D'Amico, Ernesto Damiani, Costanza Nardocci, Paolo Ceravolo, Samira Maghool, Marta Annamaria Tamborini, Paolo Gambatesa and Fatemeh Mohammadi. “Building Bridges from and Beyond the EU Artificial Intelligence Act.
