A capability approach to ethical development and internal auditing of AI technology

Responsible artificial intelligence (AI) requires integrating ethical awareness into the full process of designing and developing AI, including ethics-based auditing of AI technology. We claim the Capability Approach (CA) of Sen and Nussbaum grounds AI ethics in essential human freedoms and can increase awareness of the moral dimension in the technical decision making of developers and data scientists constructing data-centric AI systems. Our use of CA focuses awareness on the ethical impact that day-to-day technical decisions have on the freedom of data subjects to make choices and live meaningful lives according to their own values. For internal auditing of AI technology development, we design and develop a light-weight ethical auditing tool (LEAT) that uses simple natural language processing (NLP) techniques to search design and development documents for relevant ethical characterizations. We describe how CA guides our design, demonstrate LEAT on both principle- and capabilities-based use cases, and characterize its limitations.
