Flood control scheduling rule question and answer recommendation method and system based on large language model

The invention discloses a flood control scheduling rule question and answer recommendation method and system based on a large language model, and the method comprises the steps: extracting and collecting flood control scheduling rule information from a scheduling rule official document, constructing a flood control scheduling rule map, and providing external recallable data for the large language model; user questions are filtered, and the large language model is prevented from answering questions except the scheduling rule; classifying user questions according to intentions; a graph query method is used for generating a corresponding flood control dispatching Neo4j graph special CQL query statement for data recall query according to the intention classification result by using different model weights; using a recommendation generation method to generate rule-containing recommendation answers for the user according to the scheduling information recalled from the map; the big language model is finely adjusted
