Entity structured matching method and matching system, electronic equipment and storage medium

The invention discloses an entity structured matching method and system, electronic equipment and a storage medium, and relates to the technical field of artificial intelligence. The entity structured matching method comprises the steps of receiving a service request sent by a user, determining to-be-identified information based on the service request, identifying fine-grained entity information in the to-be-identified information based on a preset entity identification model, and determining first entity information based on the target knowledge graph and the fine-grained entity information, and determining target entity information based on the first entity information and a preset entity library. According to the method, fine-grained entity recognition is carried out on the demand information of the user, and then searching is carried out based on the target knowledge graph, so that the robot can more accurately understand the demand information of the user, the demand entity matched with the demand inform
