Selecting ontologies and publishing data of electrical appliances: A refrigerator example

Abstract

Application scenarios for the data generated from the Internet of Things are on the rise. For example, given the appliances’ energy consumption data, energy measurement tools now make it possible to save energy whilst efficiently controlling the consumption of different household devices. Yet, when the precise structured data describing appliance models is missing, it is difficult for such application scenarios to be realized. The developed OpenFridge ontology defines a basic vocabulary for the domain of measuring a refrigerator’s energy consumption, showing that the needed ontology schemata are already in place, but need to be identified and skillfully applied. Further, the ontology has been populated from the Web using data scraping, and the created dataset semantically describing the specifics of 1032 refrigerator models with 18665 triples, make these valuable assets for the development of further applications.
