Automated knowledge graphs for life-cycle management of coastal bridge networks

With the advancement of computational resources and the emergence of big data, digital twins have become increasingly popular as tools to enable the digital transformation of our cities. In terms of managing coastal bridge networks, digital twins show the potential to better monitor the life-cycle risk of the bridge networks by fusing the big data from disparate sources with the traditional life-cycle risk assessment models. To construct such a digital twin, a prerequisite and a main challenge are to establish a knowledge graph. The objective of this project is hence to generate a city-scale knowledge graph to represent the relationships between the needed variables related to data-driven life-cycle risk analysis of a coastal bridge network. In contrast to existing knowledge graphs developed for digital twins, the knowledge graph in this project will consider statistical correlations within a system (e.g., spatially correlated climate-related hazards) and across different systems (e.g., correlations between flooding and bridge failure).
