“a method responding in-time sequential by flexibly combining”
The content of the paper raises major concerns as well. In the introduction, I could not understand the motivation of the paper. The authors argue that the smart city services failed to be flexible enough to predict and fight the pandemic. However, I am lacking a concrete example of failure that proves the authors’ point. It is well-known that different services are hard to integrate together (this is not specific to the smart city), but I would have liked the authors to illustrate in light of the pandemic context, and maybe to the context of Korea since their contribution is specific to this geographic context in that it integrates the 12 smart city categories of Korea and the healthcare phases of Korea. The contribution is not presented in the introduction, only the problem is.
