BIM Visual Analysis at Home and Abroad Based on Knowledge Graphs

Abstract

［Objective］ Through visual analysis, an overview of the research status, the hot trends and evolutionary dynamics in the field of BIM (building information modeling) at home and abroad are comprehensively revealed. ［Method］ With the bibliometric method, the VOSviewer software is used to analyze the keyword co-occurrence in a total of 2 919 pieces of literature sourced from the CNKI （China National Knowledge Infrastructure） database and the Web of Science Core Collection database, so as to identify the current research hot spots and topic distribution in the BIM field. Through the author co-occurrence and country co-occurrence analyses, the cooperation patterns of researchers, the breadth and depth of cross-institutional communication and cooperation are evaluated. Based on the time evolution analysis, the development trend and stage characteristics of researches in the BIM field are discussed. ［Result & Conclusion］ From the point view of the number of published papers and citations in literature, China′s research strength in the BIM field is more prominent. However, the cross-institutional communication and cooperation are still insufficient compared with other countries, and the cross-development in frontier fields such as BIM+high and new technology needs to be strengthened. From the perspective of keyword and author co-occurrence results, the research hot spots at home and abroad have gradually shifted from theoretical exploration in the initial stage to engineering applications, and until now, showing a coordinated development trend of multiple perspectives such as multi-disciplinary fields, integration, greening, and intelligence.
