This book constitutes the post-conference proceedings of the First International Workshop on Value Engineering in Artificial Intelligence, VALE 2023, held in Krakow, Poland, on September 30, 2023.The 16 full papers presented  were carefully reviewed and selected. The papers have been grouped into four themes, addressing a number of research questions for each:I. Frameworks for norms and values: What are existing or new frameworks for norms and values and how can they be represented in AI systems in order to make these systems norm- and value-aware?II. Detection of moral values: Given an existing AI system, how can we figure out whether its behavior is aligned with human values?III. Learning and engineering of value-aligned policies: How can policies for implementing norms and values be acquired or designed?IV. Implementation of norms: How can norms be implemented in concrete AI applications?
