User-driven knowledge graph construction method and device and medium

The invention provides a user-driven knowledge graph construction method and device and a medium, and relates to the field of artificial intelligence, and the method comprises the steps: designing a knowledge graph representation scheme based on a user intention flow sequence behavior log answer document; constructing a knowledge graph design knowledge graph flow sequence and answer document association method through a knowledge graph representation scheme, and obtaining a document answer data set of the flow sequence; constructing an answer document generation model based on thinking chain imitation learning; and obtaining a to-be-retrieved process sequence, and generating an answer document of the to-be-retrieved process sequence through the answer document generation model and the document answer data set of the to-be-retrieved process sequence. The process sequence of the event is mined to construct the process graph, so that the knowledge graph can provide more comprehensive and accurate semantic inform
