A framework and methodology---termed LogiKEy---for the design and engineering of ethical reasoners, normative theories and deontic logics is presented. The overall motivation is the development of suitable means for the control and governance of intelligent autonomous systems. LogiKEy's unifying formal framework is based on semantical embeddings of deontic logics, logic combinations and ethico-legal domain theories in expressive classic higher-order logic (HOL). This meta-logical approach enables the provision of powerful tool support in LogiKEy: off-the-shelf theorem provers and model finders for HOL are assisting the LogiKEy designer of ethical intelligent agents to flexibly experiment with underlying logics and their combinations, with ethico-legal domain theories, and with concrete examples---all at the same time. Continuous improvements of these off-the-shelf provers, without further ado, leverage the reasoning performance in LogiKEy. Case studies, in which the LogiKEy framework and methodology has been applied and tested, give evidence that HOL's undecidability often does not hinder efficient experimentation.

为道德和法律推理设计规范理论：LogiKEY 框架、方法论和工具支持

提出了一种框架和方法——称为 LogiKEY——用于伦理推理、规范理论和道义逻辑的设计和工程。总体动机是为智能自治系统的控制和治理开发合适的手段。LogiKEy 的统一形式框架基于道义逻辑、逻辑组合和伦理-法律领域理论在表达性经典高阶逻辑 (HOL) 中的语义嵌入。这种元逻辑方法可以在 LogiKEy 中提供强大的工具支持：HOL 的现成定理证明者和模型发现者正在协助 LogiKEy 道德智能代理的设计者灵活地试验底层逻辑及其组合，与 ethico-legal领域理论，并提供具体的例子——同时进行。这些现成的证明器的持续改进，不用多说，利用 LogiKEy 中的推理性能。案例研究，其中 LogiKEY 框架和方法已被应用和测试，证明 HOL 的不可判定性通常不会阻碍有效的实验。
