The motivation of the paper is still unclear for me in the introduction, and the reasons for the limitations of smart city services are not clear in Section 2, but is much better explained later in the paper, which is a nice improvement.
There are still some "Reference not found" errors and line breaks when referring to figures in the text, but almost everything regarding the format has been fixed, which gives the revised paper a much more professional look than its previous version. Regarding the references, my point was that there are many references *with formatting mistakes in them*, and not that there are too many references in the bibliography. Please feel free to add them back if you feel they should be included.
