ABSTRACT
Smart city is a hot topic in debates about urban policy and practice across the globe. There is, however, limited knowledge and understanding about trending smart city concepts and technologies; relationships between popular smart city concepts and technologies; and policies that influence the perception and utilisation of smart city concepts and technologies. This chapter aims to evaluate how smart city concepts and technologies are perceived and utilised in cities. The methodology involves a social media analysis approach—i.e., systematic geo-Twitter analysis—that contains descriptive, content, policy, and spatial analyses. For the empirical investigation, the Australian context is selected as the testbed. The results reveal that: innovation, sustainability, and governance are the most popular smart city concepts; the IoT, AI, and autonomous vehicle technology are the most popular technologies; a balanced view exists on the importance of both smart city concepts and technologies; Sydney, Melbourne, and Brisbane are the leading Australian smart cities; and systematic geo-Twitter analysis is a useful methodological approach for investigating perceptions and utilisation of smart city concepts and technologies. The findings provide a clear snapshot of community perceptions on smart city concepts and technologies and can inform smart city policymaking.
