面向知识图谱实体对齐的实例化嵌入方法

AN INSTANCE EMBEDDING METHOD FOR KNOWLEDGE GRAPHS ENTITY ALIGNMENT

  • 摘要: 针对知识图谱实体对齐需大量的数据标注且较难适应一致性冲突问题,提出一种实例化嵌入方法;结合图卷积网络和多阶关系嵌入捕获实体链接信息;构建基于关系和属性的实例化嵌入,形成跨语言实体对齐矩阵。实验表明:所提方法可以消除数据标注需求,比现有基准方法的评价指标精度高出20%以上,具有更有效的超参数敏感性和一致性冲突鲁棒性,为跨语言知识图谱融合提供了支持。

     

    Abstract: Existing entity alignment techniques often require large amounts of labelled data, and are unable to encode multi-modal data simultaneously. Aiming at this problem, we propose an instance embedding method for knowledge graphs entity alignment. It captured the linked information by graph convolution networks and multi-order relation embedding. It constructed instantiation embedding based on relationship and attribute to form cross-language entity alignment matrix. Experimental results show that our scheme can eliminate data label requirements and obtain a general increase in the accuracy of evaluating indicator by about 20% compared with the existing methods, while it can get an effective hyperparameter sensitivity and consistency conflict robustness of aligning results, which provides support for cross language knowledge graph fusion.
