Smart City Ontologies and Their Applications: A Systematic Literature Review

The increasing interconnections of city services, the explosion available urban data, and need for multidisciplinary analysis decision making sustainability require new technological solutions to cope with such complexity. Ontologies have become viable effective tools practitioners developing applications requiring data process interoperability, big management, automated reasoning on knowledge. We investigate how what extent ontologies been used support smart services we provide a comprehensive reference problems addressed has achieved so far ontology-based applications. To this purpose, conducted systematic literature review finalized presenting ontologies, methods systems where play relevant role in shaping current cities. Based result process, also propose classification sub-domains by found, research issues that considered scientific community. highlight those which semantic technologies mostly demonstrated be enhance concept and, finally, discuss more details about some open problems.
