Systematic Literature Review on Knowledge Graphs in Construction Management from a Multi-Modal Perspective

The research of knowledge graph in construction management (KGCM) has become a current research hotspot. However, there are problems of insufficient data sources, low accuracy of information and the need for manual intervention in construction management, which needs to be improved urgently. This article adopts a hybrid review approach to comprehensively analyze the current research status of KGCM and summarizes the research results of KGCM. In addition, the gaps and future development directions are explored from a multi-modal perspective. The study shows that the research on KGCM under the multi-modal perspective still faces three major challenges: (1) Construction process modeling and optimization, (2) construction resource management and scheduling, (3) construction risk identification and response. This research provides new ideas and methods for the planning, design, construction and operation of engineering projects.
