An Expert System for Danish Traffic Law Cases (Student Abstract)

We present FÆRDXEL, an expert system for providing answers and explanations to legal questions (queries) regarding Danish traffic law cases. It utilizes a Datalog encoding of Danish traffic laws and uses SLD-resolution to answer queries. The SLD-resolution’s trace of operations can be converted into a legal explanation for the query. A user interface allows legal professionals to input case facts, ask questions, and explore explanations. Feedback from legal experts identified usability challenges and potential end-users, including traffic police and judges. Future steps include empirical evaluation of soundness, integrating punishment reasoning, and enhancing usability through natural language processing.
