Electric power heterogeneous knowledge fusion method and device

The invention relates to a power heterogeneous knowledge fusion method. The method comprises the following steps: acquiring a first triple with an entity relationship from ontology layers of at least two knowledge maps; the language model classifies entity relationships in the first triple into synonymous relationships and inclusion relationships according to relationship aggregation prompts; combining the entity relationships belonging to the synonymous relationship; obtaining a second triad with entity attributes or relation attributes from the ontology layers of at least two knowledge maps, wherein the second triad is used for storing entity attributes or relation attributes; the language model classifies attributes in the second triple into synonymous attributes and non-synonymous attributes according to attribute aggregation prompts; combining the entity attributes or relation attributes belonging to synonymous attributes; obtaining entities from instance layers of at least two knowledge maps, and dividi
