There are numerous multi-step relationship paths between entities in the knowledge graph to indicate semantic relationships between entities, as well as the neighborhood heterogeneity between relationship structures and attribute structures. In response to this problem, An entity reliable path information semantic augmentation model is proposed in this paper, which simultaneously captures and aggregates multi-source information of aligned entities and their heterogeneous neighbors, an initial reliable path reasoning algorithm to generate. The model aggregates the relationship structure, attribute structure, and entity name information reliable path of the entities for semantic augmentation, which solves the problem of domain heterogeneity in knowledge graph alignment. The paper evaluated the entity reliable path information semantic augmentation model on three datasets(WK31-15K, DBP-15K and DWY-100K)show that this model is improved by 1.5%~3.2%compared with the state-of-art entity alignment method Hits@1, which shows that the proposed method has better performance.
