Abstract
This work aims to figure out a landscape of the scientific and technological production on the Smart City concept. Smart cities have attracted the attention of both academia and industry. However, the state of the art is still unclear and most of the focus has been on literature reviews without looking at technological aspects. To achieve this objective, a scientometric dynamic methodology has been applied on paper and patent data. This methodology combines traditional systematic reviews with the analysis of networks and keywords. These dynamic analyses allow depicting the evolution of Smart City, the research and technological directions, the critical areas, the emerging topics and it reveals the position of the technological evolution with respect to the scientific one. These techniques reveal that while research papers are concerned with social aspect, the technology is mainly focused on specific technical solutions without completely looking at the citizen role. Moreover, patents are not fully embodying sustainability concepts yet.
