Nowadays, cities are a source of benefits and problems related to social, economic and environmental aspects. There is no doubt that the benefits of urbanization are drawing more and more people to live in urban centers. However, such a situation favors the creation of many threats to various socio-economic spheres. Smart cities and advanced information and communication technologies are now becoming the research area of ​​many scientists. Attempts to define and characterize the Smart City concept show how many disciplines are interested in addressing this topic. However, research on Smart City and its components lacks a clear definition of the directions of scientific research supported by practical ICT solutions, taking into account the correlation of scientific research in the field of Smart City. To this end, the authors carried out a detailed structured review of scientific articles to provide a synthetic insight into the characteristics of current smart city research. The article presents a bibliometric analysis showing the correlations of the studied phenomena in economic practice. The presentation of the author's visualization of the use of ICT in the Smart City concept based on a review of scientific articles with the use of an advanced analysis of the interdependence of identified research areas in the field of Smart City, will allow to determine the relationship between the variables and their directions and scenarios for future research. The authors also made a schematic classification of the areas of the analyzed systematic units - taxa (keywords and areas of coexistence). The VOSViewer and CitNetExplorer software used enriched the bibliometric analysis by showing the degree of correlation of the studied areas by means of visualization of network connection maps.
