摘要:

现实中的多模态知识图谱(MKGs)本质上是异构的,涉及与多样模态关联的实体。传统知识图谱嵌入(KGE)方法擅长学习实体和关系的连续表示,但通常适用于单模态设置。最近的方法扩展KGE到多模态设置,但受限于处理模态隔离,导致跨模态对齐薄弱,并依赖于简单的假设,如实体间模态可用性的均匀性。视觉-语言模型(VLMs)提供了一种强大的方法,以共享嵌入空间对齐不同模态。我们提出视觉-语言知识图谱嵌入(VL-KGE),一个框架,将VLMs的跨模态对齐与结构关系建模相结合,以学习统一的多模态知识图谱表示。在WN9-IMG和两个新的细艺术MKGs,WikiArt-MKG-v1和WikiArt-MKG-v2上的实验表明,VL-KGE在链接预测任务中优于传统单模态和多模态KGE方法。我们的结果突显了VLMs在多模态KGE中的价值,使在大规模异构知识图谱上进行更稳健和结构化的推理成为可能。

英文摘要:

Real-world multimodal knowledge graphs (MKGs) are inherently heterogeneous, modeling entities that are associated with diverse modalities. Traditional knowledge graph embedding (KGE) methods excel at learning continuous representations of entities and relations, yet they are typically designed for unimodal settings. Recent approaches extend KGE to multimodal settings but remain constrained, often processing modalities in isolation, resulting in weak cross-modal alignment, and relying on simplistic assumptions such as uniform modality availability across entities. Vision-Language Models (VLMs) offer a powerful way to align diverse modalities within a shared embedding space. We propose Vision-Language Knowledge Graph Embeddings (VL-KGE), a framework that integrates cross-modal alignment from VLMs with structured relational modeling to learn unified multimodal representations of knowledge graphs. Experiments on WN9-IMG and two novel fine art MKGs, WikiArt-MKG-v1 and WikiArt-MKG-v2, demonstrate that VL-KGE consistently improves over traditional unimodal and multimodal KGE methods in link prediction tasks. Our results highlight the value of VLMs for multimodal KGE, enabling more robust and structured reasoning over large-scale heterogeneous knowledge graphs.
