Urban geographic semantic knowledge network construction method, system and device and medium

The invention provides an urban geographic semantic knowledge network construction method, system and device and a storage medium, and the method comprises the steps: a server obtains geographic entity data, and constructs a geographic entity data set according to the geographic entity data; the server classifies the geographic entity data set according to at least one preset feature to obtain classified geographic entity data; the server constructs a semantic relation model about the geographic entity; the server obtains a semantic relationship between the geographic entity data based on the semantic relationship model and the classified geographic entity data; and the server constructs a geographic knowledge network based on a graph database, the semantic relationship and the geographic entity data set, the geographic knowledge network is constructed based on the graph database, and richer and more complete geographic position information can be provided for various geographic information services. 本发明提供了一种
