Report on the First Ethical Web Science Workshop (EWSW 2025) at the ACM Web Science Conference 2025 (WebSci 2025)

The Web Science conference series (WebSci) is an established venue for Web related research in an interdisciplinary field dedicated to understanding the complex and multiple impacts of the Web on society and vice versa. This is where the Ethical Web Science Workshop kicks in-by bringing together quantitative, qualitative and mixed methods research, including techniques from the social sciences and computer science. The Workshop aims at investigating ethics in research and Web-based data collections. To this end, explainability is a core aspect of Ethical Web Science. Systems failing to deliver data without providing accessible and meaningful to stakeholders risk perpetuating opacity and eroding trust. Hence, explainability is not only a technical problem but a fundamental ethical issue. Thus, the workshop investigates the shift in global digital discourse from a technical and societal point of view. Date: 20 May, 2025. Website: https://ethical-web-science.github.io.
