JOURNAL OF URBAN TECHNOLOGY 11 articulated thanks to the presence of citations,which indicate an active exchange of knowl- edge among researchers.However,moving towards the outer perimeter,the organization of the network changes completely.Source documents are disconnected or combined in groups that are small in number and detached from the main core. The Divergent Roots of Smart Cities Divergence,lack of cohesion,and limited intellectual exchange among researchers become even more evident when trying to find out a commonly accepted interpretation of smart cities,which is missing.This absence is highlighted in various source documents,such as those produced by Alkandari et al.(2012),Chourabi et al.(2012),Hollands (2008),and Paskaleva(2011).Many definitions of the smart city are provided in scholarly literature and they overlap one another,making it difficult to obtain a common understanding and agreement as to what it means.To illustrate this trend,some of these definitions snany have been extracted from the source documents and reported in Table 1.
