  Intelligence Everywhere is predicated on the seamless integration of IoT
networks transporting a vast amount of data streams through many computing
resources across an edge-to-cloud continuum, relying on the orchestration of
distributed machine learning models. The result is an interconnected and
collective intelligent ecosystem where devices, systems, services, and users
work together to support IoT applications. This paper discusses the
state-of-the-art research and the principles of the Intelligence Everywhere
framework for enhancing IoT applications in vertical sectors such as Digital
Health, Infrastructure, and Transportation/Mobility in the context of
intelligent society (Society 5.0). It also introduces a novel perspective for
the development of horizontal IoT applications, capable of running across
various IoT networks while fostering collective intelligence across diverse
sectors. Finally, this paper provides comprehensive insights into the
challenges and opportunities for harnessing collective knowledge from real-time
insights, leading to optimised processes and better overall collaboration
across different IoT sectors.
