Zusammenfassung: | The invention relates to a construction method of a space-based data-oriented target time sequence knowledge graph. The construction method comprises the following steps: S100, constructing a target body, a radar body, a region body and an event body; s200, performing knowledge extraction according to the target body, the radar body, the region body and the event body; s300, performing knowledge fusion on a knowledge extraction result to obtain a target knowledge graph; s400, embedding a time model in the target knowledge graph; and S500, constructing the time sequence knowledge graph according to the structure in the step S400. According to the method, a processing mechanism about time and space is added on the basis of a traditional knowledge graph, multi-source heterogeneous data can be extracted and modeled, and support can be better provided for intelligence analysis, activity law analysis, auxiliary decision making and subsequent target recognition.
