Abstract
The Canadian Smart Cities Challenge grant program provided a unique opportunity to investigate what communities across Canada mean when they propose becoming a smart city. We investigated the utility of human-centered machine learning to analyze 137 grant proposals submitted to this program, containing approximately 1.5 million words. We explored whether results generated by topic modeling aligned with or differed from standard smart city definitions in the literature and current urban applications of topic modeling. The analysis resulted in three main findings. First, the prevalence of topics describing rural, regional and Indigenous communities challenged conventional definitions of “city” in the smart city. Second, context (e.g., local culture and language) inferred what constitutes smart, although smartness was not focused on technical innovations. Finally, our abductive approach generated new insights missing from conventional smart city research methods, including 40 percent of finalists and all four winning cities being identified as most representative users of topics.
