Functional Status Information refers to a person’s overall mental and physical health. Collecting and analyzing Function Status Information data is crucial for addressing the needs of a growing elderly population, as well as for providing effective care to those with chronic diseases, multiple health issues, or disabilities. Knowledge Graphs provide an effective method for organizing and representing Functional Status Information data in a structured way. Furthermore, they can also allow reasoning over this data to create personalized health support solutions that assist people in maintaining a healthy lifestyle and improving daily living. In this paper, we describe the integration of our Functional Status Knowledge Graph, namely FuS-KG , into a real-world application run within a large-scale living lab involving more than 4,000 people. We provide the road map of this experience including the challenges, the platform’s architecture, the focus on the knowledge layer, the evaluation and the insights observed.

The use of knowledge resources in the digital health domain is a trending activity significantly grown in the last decade. In this paper, we present HeLiS : an ontology aiming to provide in tandem a representation of both the food and physical activity domains and the definition of concepts enabling the monitoring of users’ actions and of their unhealthy behaviors. We describe the construction process, the plan for its maintenance, and how this ontology has been used into a real-world system with a focus on “Key to Health”: a project for promoting healthy lifestyles on workplaces.
