论文摘要
知识图的关系预测旨在预测实体之间的缺失关系。尽管有归纳关系预测的重要性,但大多数以前的作品都限于转导设置,并且无法处理以前看不见的实体。最新提出的基于子图的关系推理模型为围绕候选三胞胎的子图结构的联系提供了替代方案。但是,我们观察到这些方法通常忽略了提取子图的定向性质,并削弱了关系信息在子图建模中的作用。结果,他们无法有效处理不对称/反对称三重态,并且为目标三重态产生不足的嵌入。为此,我们介绍了一个\ textbf {c} \ textbf {o} mmmunicative \ textbf {m} essegage \ textbf {p} \ textbf {i} nductive re \ textbf {l textbf {l} r \ textbf {局部定向子图结构,并具有对处理实体无关的语义关系的剧烈归纳偏见。与现有模型相反,编译通过交流内核增强了边缘和权利之间的信息相互作用,并实现了足够的关系信息。此外,我们证明了编译可以自然地处理不对称/反对称关系,而无需通过提取定向的封闭子图的爆炸性增加模型参数的数量。广泛的实验表明,与具有变异感应设置的常用基准数据集的最新方法相比,性能增长。
Relation prediction for knowledge graphs aims at predicting missing relationships between entities. Despite the importance of inductive relation prediction, most previous works are limited to a transductive setting and cannot process previously unseen entities. The recent proposed subgraph-based relation reasoning models provided alternatives to predict links from the subgraph structure surrounding a candidate triplet inductively. However, we observe that these methods often neglect the directed nature of the extracted subgraph and weaken the role of relation information in the subgraph modeling. As a result, they fail to effectively handle the asymmetric/anti-symmetric triplets and produce insufficient embeddings for the target triplets. To this end, we introduce a \textbf{C}\textbf{o}mmunicative \textbf{M}essage \textbf{P}assing neural network for \textbf{I}nductive re\textbf{L}ation r\textbf{E}asoning, \textbf{CoMPILE}, that reasons over local directed subgraph structures and has a vigorous inductive bias to process entity-independent semantic relations. In contrast to existing models, CoMPILE strengthens the message interactions between edges and entitles through a communicative kernel and enables a sufficient flow of relation information. Moreover, we demonstrate that CoMPILE can naturally handle asymmetric/anti-symmetric relations without the need for explosively increasing the number of model parameters by extracting the directed enclosing subgraphs. Extensive experiments show substantial performance gains in comparison to state-of-the-art methods on commonly used benchmark datasets with variant inductive settings.
