2. INTRODUCTION Modern homes are not any more environments where various devices perform separate and isolated tasks but a system of distributed smart objects working together in a reliable and predictable manner

3. INTRODUCTION In the field of Ambient Assisted Living (AAL), smart home provides tailored services that assist users for a better, healthier and safer life in their preferred living environment A smart home is a residence equipped with various smart objects which aim at anticipating and responding to the needs of its dwellers, in order to promote their comfort, well-being, security and entertainment

4. INTRODUCTION The smart home design and development poses a number of technical challenges New strategies have to look for smart and efficient ways to capture and view disparate sets of data, aiming at extracting meaningful knowledge The efforts are addressed in particular toward handling Big Data

5. MATERIALS AND METHODS A lot of work has been done on volume and velocity, whereas the increase of data variety remains much more difficult to solve It is necessary to adopt a new model of collaboration between the various involved sources, regardless of the formats used to represent the data

6. MATERIALS AND METHODS Various generic models of interoperability have been proposed by researchers D4All proposes the Virtual Home Framework (VHF) : it represents a possible pattern based on Sematic Web technologies to be applied to solve such issue of integration On the basis of the VHF, the herein presented research analyzes and designs a technological platform in which the data are enriched with semantic metadata in order to integrate different types of Smart Objects

8. A significant study during this research has regarded the identification of a valid Semantic Repository The managed data comprise: the models, as representation of the knowledge about home environment the population, compliant to the models the derivation rules needed to properly entail the implicit knowledge It must also provide reasoning capability

9. ADVANTAGES Ease the interoperability of different devices, using a formal semantics Efficiently model and manage distributed data Exploit generic tools that can infer from and reason about an ontology, thus providing a generic support that is not customized on the specific domain Allow Semantic Search through the Knowledge Graph

10. FUTURE STEPS Validation and test of the proposed solution The design and development has to be paired with a quantitative analysis of performance Dealing with legacy systems whose knowledge models are so huge or complex to hinder the integration process
