Visualization analysis of domestic and overseas intelligent construction assisted by mapping knowledge domains

As a new way of engineering construction, intelligent construction has won more and more attention in recent years. In order to comprehensively understand the research and development in the field of intelligent construction, China national knowledge internet (CNKI) and Web of Science domestic and foreign databases were employed as data sources with the assistance of visual tools CiteSpace, the domestic and foreign intelligent construction literature published over 2000-2019 were sorted out, the map of scientific knowledge was drawn, and multi-dimensional comparative analysis was carried out in terms of the research topics, evolution trends and research hotspots, respectively. It is concluded that the development of intelligent construction is increasingly inseparable from human education, psychological will and social development. In this process, the evolution trend of the field of intelligent construction at home and abroad is much consistent, that is, the information source is gradually abundant, the information technology has developed in a multidisciplinary way, and the information application mode has evolved from combined one to integrated one. The research preferences at home and abroad have their own emphasis, the literature in the source of foreign journals is more inclined to analyze the specific application in engineering, while the domestic literature is inclined to analyze such application at the macro level, and pays more attention to building an autonomous theoretical framework. Nowadays, the integrated application of new multi-technologies has become the key research object in the field of intelligent construction. © 2021, Editorial Office of Journal of Building Structures.
