Summary:The invention provides a knowledge graph construction method and a recommendation method and device based on a knowledge graph database, and the method comprises the steps: carrying out the semantic feature coding of a target text, and obtaining a first feature sequence corresponding to the target text; and performing entity relationship identification on the first feature sequence corresponding to the target text to obtain an entity relationship set corresponding to the target text. And based on a first feature sequence corresponding to the target text and the entity relationship set, determining an entity identifier sequence of each entity relationship in the entity relationship set corresponding to the target text. And extracting a head entity and a tail entity corresponding to each entity relationship in the entity relationship set from an entity identifier sequence corresponding to each entity relationship in the entity relationship set corresponding to the target text, and according to each entity relat
