FÆRDXEL: An Expert System for Danish Traffic Law

We present F{\AE}RDXEL, a tool for symbolic reasoning in the domain of Danish traffic law. F{\AE}RDXEL combines techniques from logic programming with a novel interface that allows users to navigate through its reasoning process, thereby ensuring the system's explainability. Towards the goal of better understanding the value of F{\AE}RDXEL, two evaluations of the system have been performed: (1) An empirical evaluation showing that for a selection of court cases, the conclusions of F{\AE}RDXEL align with those of Danish judges. (2) A qualitative evaluation from legal experts indicating that this work has potential to become a foundation for real-world AI tools supporting professionals in the Danish legal sector.
