At present，the application and improvement of artificial intelligence technology in the field of law creation and implementation still cannot overcome the difficult barrier of normative deduction represented by Jorgensen’s conundrum. The derivation jurisprudence is precisely the establishment of a system of legal normative forms by symbolizing legal propositions and completing the derivation process through basic principles and rules. The concept of legal derivation is a world first，providing a basic model for the design of jurisprudence by AI technology，making the application of AI technology in the legal field provide more comprehensive，accurate and reliable，providing a broader prospect for the seamless connection between AI technology and the rule of law，and at the same time providing solutions to many difficulties existing in traditional jurisprudence.
