Knowledge graph construction method and device based on big language model knowledge distillation

The embodiment of the invention discloses a knowledge graph construction method and device based on knowledge distillation of a large language model. The method comprises the following steps: acquiring metadata; the metadata comprises relation description information of the knowledge graph and a plurality of entity pairs corresponding to the relation description information; splicing the relation description information of the metadata and the entity pair to obtain a spliced statement, performing synonymous rewriting on the spliced statement, and extracting the rewritten spliced statement to obtain a relation description set; the relation description set comprises multiple pieces of relation description information in the rewritten assembled statement; according to the relation description set and the entity pairs, constructing cue words, and according to the cue words, obtaining a candidate entity pair set by utilizing a knowledge distillation module; and generating a knowledge graph according to the candida
