A current vision in the area of ICT-supported independent living of the elderly involves populating the home with electronic devices (“things”), i.e. sensors and actuators, and linking them to the Internet. Creating such an Internet-of-Things (IoT) infrastructure is done with the ambition to provide automated information gathering and processing on top of which e-services can be built, E-care@home.
While the information can be stored in the form of PHRs, it needs to be linked with e.g. EHRs, home-service documentation and documentation generated by information from end-users and their informal caregivers. Semantic-interoperability related technologies play a central role in ambient intelligence systems and their components such as pervasive/ubiquitous computing, profiling, context awareness, and human-centric design. While these things need to “talk” to each other, the heterogeneity of the services, devices and communication technologies is a major challenge for expanding generic IoT technologies to efficient ICT-supported services for elderly. This project is designed to address this interoperability challenge. Semantic interoperability is seen as a key requirement for gaining the benefits of computerization of the health domain and much effort has been invested to understand and provide solutions of the problem of achieving semantic interoperability.
E-care@home is a “SIDUS – Strong Distributed Research Environment” funded by the Swedish Knowledge Foundation – a research financier for universities with the task of strengthening Sweden’s competitiveness and ability to create value. Duration 01.03.2015 – 31.02.2020

The SmartEnv ontology is described in terms of its modules representing different aspects including physical and conceptual aspects of a smart environment. We propose the use of the Ontology Design Pattern (ODP) paradigm in order to modularize our proposed solution, while at the same time avoiding strong dependencies between the modules in order to manage the representational complexity of the ontology. The ODP paradigm and related methodologies enable incremental construction of ontologies by first creating and then linking small modules. Most modules (patterns) of the SmartEnv ontology are inspired by, and aligned with, the Semantic Sensor Network (SSN) ontology, however with extra interlinks to provide further precision and cover more representational aspects. The result is a network of 8 ontology patterns together forming a generic representation for a smart environment. The patterns have been submitted to the ODP portal and are available on-line at stable URIs.},
