This book is the second open access volume in a series reporting results of the EU MUHAI project. The first volume was published as Steels, L., ed. (2022) Foundations for Meaning and Understanding in Human-centric AI. Venice International University, Venice. (https://zenodo.org/record/ 6666820). In this second volume the challenge of meaning and understanding is explored with concrete case studies that are all about understanding everyday activities in the real world. The case studies come from the domain of cooking: the preparation and execution of recipes and the invention of recipes by constructing variations of existing ones. The different papers push the state of the art in technologies needed to operationalize understanding: computational linguistics, semantic web technology, knowledge-based robotics, and generative AI. There are also contributions on data structures and strategies for integrating these components in the construction of integrative narrative networks.
