融合关系层次结构的知识图谱嵌入

KNOWLEDGE GRAPH EMBEDDING METHOD WITH RELATION HIERERCHICAL STRUCTURE

  • 摘要: 针对目前知识图谱嵌入方法大都侧重于三元组中的实体和关系信息,忽略了三元组之外与关系相关的丰富信息,提出一种融合关系层次结构信息的知识图谱嵌入方法CompGCN-RHS。在关系表示中融入关系的层次结构信息,将实体和关系联合进行嵌入学习,通过在聚合邻居节点信息时引入注意力机制来学习不同邻居节点对于中心节点的不同贡献。在数据集Sport上该方法的MRR、Hits@1分别提升2.2百分点和2.3百分点;在Location上分别提升了4.7百分点和6百分点,实验结果验证了该方法的有效性。

     

    Abstract: Aimed at the current knowledge graph embedding methods that mostly focus on the entity and relationship information in the triples, thus ignoring the rich information related to the relationships other than the triples, a knowledge graph embedding method, CompGCN-RHS, fused with relational hierarchical structure information is proposed. The hierarchical structure information of the relationship was incorporated into the representation of the relationship, the entity and the relationship were combined for embedded learning, and the attention mechanism was introduced to learn the different contributions of different neighbor nodes to the central node when the neighbor node information was aggregated. On the dataset Sport, the MRR and Hits@1 of this method were increased by 2.2 percentage points and 2.3 percentage points respectively; on the Location, they are increased by 4.7 percentage points and 6 percentage points respectively. The experimental results verified the effectiveness of the method.
