Table 1: Normalized keywords list. assessment\", \"information management\", and \"digital storage\". The predominance of \"BIM\" within the keyword network underscores its pivotal role as a linchpin technology in industrialized construction. Its multifaceted functionalities, including information management and digital storage, constitute foundational pillars underpinning the realization of digital collaboration and information integration within industrialized construction workflows. Meanwhile, the prominence of \"precast elements\" reflects the increasing use of precast elements, which relies heavily on digital technologies for standardized and modular design, manufacturing, and assembly. The frequent appearance of \"life cycle assessment\" suggests a growing emphasis on sustainability considerations, with digital tools being leveraged to optimize building performance and minimize environmental impact. Collectively, these keyword connections depict an industrialized construction sector harnessing digital technologies to streamline conventional construction processes, enhance information collaboration, and improve overall project effectiveness. Furthermore, the Avg. Pub. Year metric provides valuable insights into the temporal evolution of research interests, enabling the identification of emerging trends in recent years. For instance, the relatively recent average publication year of keywords such as \"digital twin\", \"structural health monitoring\", \"augmented reality\", \"blockchain\", and \"machine learning\" indicates that these technologies are gradually gaining prominence in industrialized construction. The emergence of these technologies suggests a continuous exploration of avenues toward virtual-reality integration, human-machine interaction, building structural monitoring, information security and transparency, and intelligent decision-making within the field.
