Abstract
En 中文
Artificial intelligence (AI) is spreading rapidly in the construction domain with high expectations and distinct innovation challenges. While many scholars have conducted literature reviews on the development status of AI in construction, patent data, which can objectively reflect technological evolution, is rarely analyzed. This paper conducted the patent analysis to reveal the application hotspots and evolutionary trends of AI in construction. Descriptive analysis showed that China held the majority of patents and the United States played a crucial role in knowledge transfer. The results further indicated that machine learning and computer vision were the most prevalent technologies, while structural health monitoring and safety management were the hottest topics. Additionally, this paper depicted the technology transfer landscape, and forecasted the evolutionary trends of AI technologies. This paper provides valuable insights into AI in construction from a new perspective of patent, and offers references to engineers, managers and policymakers in this field.
