Research on Spatio-temporal Semantic Digital Baseplate Technology and Its Application in Logistics Field
With the advancement of digital twin in different fields,the traditional digital baseplate can no longer meet the more intelligent needs of spatio-temporal reduction and deduction.In this paper,the concept of spatio-temporal semantic digital baseplate(STSDB)is proposed,and its overall architecture and each module function are illustrated with a real scenario of logistics.Driven by data and knowledge,the data-driven portrait and spatio-tempord semantic?knonledge groph are constructed,and the key technologies such as address segmentation and fusion and spatio-temporal semantic knowledge graph are analyzed.Finally,this paper briefly introduces the application of STSDB in smart logistics,and shows its abilities of spatio-temporal restoration and spatio-temporal deduction.
