Knowledge graph data cleaning method and device

The invention discloses a knowledge graph data cleaning method and device, and the method comprises the steps: obtaining a to-be-cleaned knowledge graph, the to-be-cleaned knowledge graph comprises a plurality of entities and relationships, and two entities and the relationships between the entities form a triple; according to the to-be-cleaned knowledge graph and all the triples in the to-be-cleaned knowledge graph, a knowledge graph embedding model and a triple classification model are trained, and the knowledge graph embedding model and the triple classification model can promote each other; using the trained triple classification model to classify triads in the knowledge graph to obtain wrong triads; inputting the wrong triad into a trained knowledge graph embedding model to obtain the global confidence of the wrong triad; and repairing the wrong triple through the global confidence to obtain a cleaned knowledge graph. 本发明公开了一种知识图谱数据清洗方法及装置，该方法包括：获取待清洗知识图谱，所述待清洗知识图谱包括若干实体和关系，其中两个实体和它们之间的关系组成一个三元组；根据所述待清洗知
