Intelligent water conservancy-oriented AI knowledge base construction method and system

The invention discloses an AI knowledge base construction method and system for intelligent water conservancy. The method comprises the steps of obtaining related text information of an irrigation area; based on a Light NER model, identifying different types of entities in the related text information of the irrigation area, and naming the entities; based on a KnowPrompt model, extracting a relationship between the entities; based on a TransD model, converting a relationship between entities into points in a low-dimensional vector space so as to construct an intelligent water conservancy AI knowledge graph library; the TransD model provides two vectors for each entity and relationship: one representation vector and one projection vector; the representation vector is used for directly representing the entity or the relation, and the projection vector is used for constructing a specific projection matrix of the entity or the relation. The constructed intelligent water conservancy AI knowledge graph database has
