Space-time big data depth analysis method and system based on knowledge graph

The invention relates to the technical field of spatio-temporal data analysis, and particularly discloses a spatio-temporal big data deep analysis method and system based on a knowledge graph. The system comprises a basic configuration module, a historical data table structure forming module, a format labeling module, a classification template construction module, a classification template configuration module, a semantic analysis model construction module, a classification matrix construction module, a guide link construction module and an identification module. Before the knowledge graph is utilized for classification, a data export mechanism is constructed, the data is exported from the database according to the set table structure, and the data structure features are limited, so that the exported data is spatio-temporal data, other data are directly filtered out, and when the knowledge graph is utilized for classification, the data export efficiency is greatly improved. Classifying and labeling according
