Abstract The construction of smart cities can effectively improve the capability of urban governance and operation and break the dilemma of modern urban development. In this paper, we aim to explore how to use big data in urban physical, social, and cyber spaces to construct smart cities. Relying on the three-world theory to analyze the composition of urban space, the concept of urban digital space was proposed to help achieve the construction of smart cities, and city profiling was accordingly presented as a construction method of urban digital spaces and city profiles. According to the goal of constructing urban digital space, we first analyzed the concept of the city profile. Then, we illustrated how to realize the construction of city profiles through urban facet modeling and profiling with smart data. Finally, we discussed the feasible applicable fields of city profiles and analyzed three typical application scenarios in detail. The urban digital space constructed by city profiling can provide a panoramic view of the urban operating conditions, treating cities as organisms that are assisted by smart data to govern, operate, and develop, and then intelligent information services can be provided to users.
