Are you interested in both smartness and the city in the smart city concept?
Summary of the article titled Ontological review of smart city research from 2017 by Arkalgud Ramaprasad, Aurora Sánchez-Ortiz and Thant Syn, presented at the Twenty-third Americas Conference on Information Systems.
Since we are investigating the future of cities, I thought it would be interesting to see how academic research investigated smart cities in 2016. This article investigates how smartness is very much interesting for the research community, but the city seems largely unexplored in the smart city term.
As the most important things, I would like to highlight 3 aspects:

The introduced ontological framework approaches smart cities from smartness with structure, functions, focus and semiotics and city with stakeholders and outcomes which can be used to investigate any smart city initiative or research.
In the investigated research, the authors found more focus on the structure aspect with systems and IT than on stakeholders and outcomes.
Researchers should consider the interdisciplinary nature of the smart city research and must integrate technological, social, and urban aspect of the smart city with the aim to achieve the desired outcomes in a more unified approach.

Abstract: The meaning of the word “city” has evolved since the first urban civilization was labeled as such more than 5,000 years ago. The concept of Smartness in Cities appeared initially because of the advancements in information technology; now cities are working diligently towards being considered “Smart”. However, the term Smart City is still conceptually vague and sometimes biased towards the use of information technology, and not on the city. This article a) presents an ontological framework of Smart City which is logically constructed but grounded in the literature of Smart Cities, and b) maps 373 journal articles—published in 2016 on the topic “smart city”—onto the framework. The mapping reveals that Smart City research in 2016 mainly focuses on the Smart part of the framework, specifically the structural elements, while the City part remains largely unexplored.
