Abstract
In recent years, cities have undergone a dramatic evolution as they become increasingly connected, data‐rich environments. Urban artificial intelligence (AI) has emerged as a transformative force, empowering city planners, policymakers, and researchers to address complex challenges ranging from resource management to public safety. However, the sheer abundance of data in contemporary urban settings also presents significant ontological challenges that become even more crucial when undertaking urban planning. These challenges revolve around the conceptualisation, classification, and integration of heterogeneous data sources into coherent models capable of supporting intelligent decision-making. In this article, we examine these ontological issues, discuss existing frameworks that aim to unify fragmented information, and explore the practical implications for urban AI applications. The thesis is that ontologies, which are structured and formal representations of knowledge, offer a powerful tool to address the challenges outlined above, while serving as a blueprint for defining, categorising, and interrelating the entities present in urban environments and put to work in urban planning.
