FAIR-PReSONS, a DG JUST project, funded by the European Union aims to address and mitigate gender bias in recidivism data to ensure fair and equitable decisions in the criminal justice systems at the national and European level. The project focuses on the collection and digitalisation of data from prison establishments and offender management systems(OMS) across a number of participating countries (Greece, Portugal and Bulgaria), structuring this data into knowledge graphs, and making it accessible via a dedicated data portal. The project employs advanced algorithms and integrates knowledge graphs as well as artificial neural networks (ANNs), aiming to enhance the accuracy and explainability of predictions. This holistic approach to fair AI aspires to support unbiased decision-making, thereby assisting judges and legal practitioners in their efforts.
