“…Representation, management and application of the heterogeneous data in the smart home data space to provide more intelligent and personalized services for home users still have been considered as a challenging research and industrial topic. Recently, ontology theory and technology have been identified as the representative promising means that can be used to address data, knowledge, and application heterogeneity [10,11,12,13,14,15], as well as to construct the service-oriented framework in smart home environments [16,17,18,19,20,21]. Inspired by the previous research achievements in the proposals, a scheme of ontology-based data semantic management and application is proposed in this paper to address the challenges put forwarded by the continuous expanding smart home data space, which has the following main contributions.…”
