The invention provides an
aerospace application
knowledge graph construction method, device,
system and equipment and a medium, and relates to the technical field of
artificial intelligence, and the method comprises the steps: obtaining multi-
modal data; based on the data types,
data processing is carried out on the
modal data, and lightweight markup language texts and embedded vectors are obtained; performing
knowledge extraction on the lightweight markup language text on the basis of a preset cue word and a large
language model to obtain
metadata information, and constructing an entity relationship triple on the basis of a relationship between entities and the
metadata information; and based on the
aerospace knowledge file number information, determining an association relationship among the
aerospace knowledge file, the lightweight markup language text, the embedded vector and the entity relationship triple, and constructing the aerospace application
knowledge graph according to the association relationship and the entity relationship triple. According to the space application
knowledge graph constructed by the method, the space application field entities and the association relationship can be accurately presented, and efficient and accurate knowledge support is provided for space application knowledge
questions and answers.
