15 – Algorithmic Transparency in the Public Sector Case studies of repositories of public algorithms in Chile, the EU and the UK

As part of a broader project aimed at studying algorithmic transparency in the public sector, with an emphasis on assessing both reactive and proactive transparency instruments that help governments comply with algorithmic transparency principles, standards, and rules, this report focuses on the development and management of public algorithm repositories (GPAI, 2024). These repositories are essential for fostering "meaningful transparency" and serve as a key tool in ensuring accountability to independent stakeholders, including citizens and government agencies (Suzor et al., 2019). This report explores the strengths, weaknesses, and challenges involved in building these instruments, as well as their diverse uses, users, and associated costs. It examines how transparency tools complement one another and contribute to goals such as explainability and accountability. To further understand these objectives, this report scrutinises three case studies of public algorithm repositories, providing a comprehensive overview of key findings. The selected cases represent a diverse range of factors, including the type of organisation managing the repository and the scope of its database. This will allow us to evaluate how these tools contribute to public value creation and enhance transparency in governments and societies' use of algorithms and AI technologies.
