  • Knowledge graph-driven groundwater-oriented method and device for building risk warning
    Patent number: 12688337
    Abstract: A knowledge graph-driven groundwater-oriented method for building risk warning includes: extracting a relationship quadruple between groundwater level change and building structure change based on collected groundwater level data and building data; creating a cross-domain knowledge graph based on the relationship quadruple, and associating two different fields; updating the cross-domain knowledge graph in real time to realize the building risk warning caused by groundwater level changes. The risk warning is based on the causal relationship reflected in the factual data, making the risk warning more accurate, which can effectively solve the problem of the lack of risk warning system for buildings due to groundwater level changes in the related art.
