| Abstract_FL | Entity alignment is the task of identifying entities from different knowledge graphs that point to the same item and is important for KG fusion.Most of the existing approaches are based on graph neural networks that learn the entities embedding by modeling the neighborhood information of the entities.However,graph neural networks-based approaches have difficulty learning triples information in knowledge graphs,the triples information is not sufficiently utilized.In order to solve this problem,an entity alignment model with joint triple embedding is proposed in this paper.The proposed model computes a triple embedding for each entity and then uses this triple embedding for entity alignment.In addition,consider-ing that the relations in the knowledge graphs have different types,in order to exploit these relation types,a relation type-aware calculation method of triple embedding is proposed.Meanwhile,constraints based on relation types are added to this model,to learn the mapping properties of relations.Experiments conducted on three real-world datasets show that this approach outperforms state-of-the-art methods,the effectiveness of the proposed method is verified. |
