摘要:

知识图谱嵌入(KGE)技术在将符号化知识图谱(KGs)转换为数值表示方面发挥着关键作用,从而为知识增强应用优化各类深度学习模型。与实体不同,知识图谱中的关系是语义的载体,对其进行精准建模对KGE模型的性能至关重要。首先,本文探讨了关系固有的复杂映射属性,如一对一、一对多、多对一和多对多映射,全面总结了基于关系感知映射的模型、利用特定表示空间的模型、基于张量分解的模型以及基于神经网络的模型。其次,聚焦于捕获对称性、非对称性、逆关系、组合关系等各类关系模式,本文综述了采用改进张量分解的模型、基于改进关系感知映射的模型以及利用旋转操作的模型。随后,考虑到实体间隐含的层次关系,本文介绍了融合辅助信息的模型、基于双曲空间的模型以及利用极坐标系的模型。最后,针对稀疏知识图谱、动态知识图谱等更复杂的场景,本文讨论了潜在的未来研究方向,探索了将多模态信息融入KGE、利用规则增强关系模式建模、开发在动态KGE场景下捕获关系特征的模型等创新思路。

英文摘要:

Knowledge Graph Embedding (KGE) techniques play a pivotal role in transforming symbolic Knowledge Graphs (KGs) into numerical representations, thereby enhancing various deep learning models for knowledge-augmented applications. Unlike entities, relations in KGs are the carriers of semantic meaning, and their accurate modeling is crucial for the performance of KGE models. Firstly, we address the complex mapping properties inherent in relations, such as one-to-one, one-to-many, many-to-one, and many-to-many mappings. We provide a comprehensive summary of relation-aware mapping-based models, models that utilize specific representation spaces, tensor decomposition-based models, and neural network-based models. Next, focusing on capturing various relation patterns like symmetry, asymmetry, inversion, and composition, we review models that employ modified tensor decomposition, those based on modified relation-aware mappings, and those that leverage rotation operations. Subsequently, considering the implicit hierarchical relations among entities, we introduce models that incorporate auxiliary information, models based on hyperbolic spaces, and those that utilize the polar coordinate system. Finally, in response to more complex scenarios such as sparse and dynamic KGs, this paper discusses potential future research directions. We explore innovative ideas such as integrating multimodal information into KGE, enhancing relation pattern modeling with rules, and developing models to capture relation characteristics in dynamic KGE settings.
