スマートシティ技術に倫理的行動を持たせる新アプローチ(How to Make ‘Smart City’ Technologies Behave Ethically)

ノースカロライナ州立大学(NC State)の研究者らは、スマートシティ技術を倫理的に運用するための理論モデル「Agent-Deed-Consequence(ADC)モデル」を提案した。AIが公共安全や交通制御などを担う際、人間のように「行為者の意図」「行為そのもの」「結果」の三要素から道徳的判断を行うよう設計する手法である。これは義務論的論理(deontic logic)を基盤とし、「何が起こるべきか」を数理的に表現できる点が特徴。例えば、救急車が通行する際の信号制御を正当化し、不正な車両による模倣行為を拒否するなどの判断をAIが自律的に下せる。研究は国立科学財団(NSF)の支援を受け、『Algorithms』誌に掲載され、今後シミュレーションおよび実環境での検証が予定されている。

スマートシティ技術に倫理的行動を持たせる新アプローチ(How to Make ‘Smart City’ Technologies Behave Ethically)

Abstract

Smart cities are an emerging technology that is receiving new ethical attention due to recent advancements in artificial intelligence. This paper provides an overview of smart city ethics while simultaneously performing novel theorization about the definition of smart cities and the complicated relationship between (smart) cities, ethics, and politics. We respond to these ethical issues by providing an innovative representation of the agent-deed-consequence (ADC) model in symbolic terms through deontic logic. The ADC model operationalizes human moral intuitions underpinning virtue ethics, deontology, and utilitarianism. With the ADC model made symbolically representable, human moral intuitions can be built into the algorithms that govern autonomous vehicles, social robots in healthcare settings, and smart city projects. Once the paper has introduced the ADC model and its symbolic representation through deontic logic, it demonstrates the ADC model’s promise for algorithmic ethical decision-making in four dimensions of smart city ethics, using examples relating to public safety and waste management. We particularly emphasize ADC-enhanced ethical decision-making in (economic and social) sustainability by advancing an understanding of smart cities and human-AI teams (HAIT) as group agents. The ADC model has significant merit in algorithmic ethical decision-making, especially through its elucidation in deontic logic. Algorithmic ethical decision-making, if structured by the ADC model, successfully addresses a significant portion of the perennial questions in smart city ethics, and smart cities built with the ADC model may in fact be a significant step toward resolving important social dilemmas of our time.
