OPICE: Ontology-Guided Pseudo-Label Generation and Inter-Modal Consistency Enhancement for Self-Supervised Multi-Modal Entity Alignment

Yingdi Wang, Ziyu Guo, Yongheng Mu, Xue Li et autres

Multi-modal entity alignment (MMEA) identifies identical real-world entities across two multi-modal knowledge graphs. Most existing methods heavily rely on costly manually labeled seed alignments; in response, self-supervised MMEA has emerged to reduce this dependency. However, current self-supervised approaches suffer from two key …
