Abstract
Cities worldwide are facing the challenge of digital information governance: different and competing service providers operating Internet of Things (IoT) devices often produce and maintain large amounts of data related to the urban environment. As a consequence, the need for interoperability arises between heterogeneous and distributed information, to enable city councils to make data-driven decisions and to provide new and effective added value services to their citizens. In this paper, we present the Urban IoT suite of ontologies, a common conceptual model to harmonise the data exchanges between municipalities and service providers, with specific focus on the sharing mobility and electric mobility domains.
Highlights
E According to the United Nations, today 55% of the world’s population lives in urban areas,1 a proportion that R is expected to increase to 68% by 2050.2 For the last decade, our cities have been digitally instrumented in many different ways, becoming the producers of a continuously increasing wealth of data, that spans multiple humanR activities and business domains
As a consequence, exchanging data with the city councils and between organizations becomes a challenge: a strong urgency for interoperability arise, with the need for common languages and interfaces. Our work addresses this interoperability challenge, by designing a modular suite of ontologies for Urban Internet of Things (IoT) devices, with specific modules dedicated to sharing mobility and electric mobility
O To complement the description of the Urban IoT ontologies we report general statistics about the different modules developed, and we discuss the evaluation of the modules considering pitfalls detected by automatic scanning tools and well-established ontology evaluation criteria
Summary
E According to the United Nations, today 55% of the world’s population lives in urban areas, a proportion that R is expected to increase to 68% by 2050.2 For the last decade, our cities have been digitally instrumented in many different ways, becoming the producers of a continuously increasing wealth of data, that spans multiple human. R SENSORIS specification and other similar projects, the Urban IoT ontologies focus on the exchange of macro-data from different service providers and do not investigate the details of communication protocols between devices. The. R initial release of the Urban IoT ontologies models the sharing and electric mobility domains, but the ontologies aim at offering core concepts for semantic interoperability of different IoT-enabled services in a smart city. The Open Mobility Vocabulary (MobiVoc) was reused This ontology, developed with the support of industrial partners, is mainly based on Datex II, the European standard for traffic information and traffic data, and currently describes electric charging points, parking facilities and highway roadworks sites. 12https://schema.org/ 13https://velopark.ilabt.imec.be/openvelopark/vocabulary 14http://schema.mobivoc.org/ 15https://www.datex2.eu/ 16https://joinup.ec.europa.eu/collection/semantic-interoperability-community-semic 17https://joinup.ec.europa.eu/solution/e-government-core-vocabularies 18Cf. for example the Italian profiles defined at https://github.com/italia/daf-ontologie-vocabolari-controllati. 19http://www.w3.org/2003/01/geo/ 20https://ciudadesabiertas.es/ 21http://vocab.ciudadesabiertas.es/def/transporte/bicicleta-publica
