Researchers have introduced MGDT, a new framework for Multimodal Knowledge Graph Completion (MKGC) that aims to improve the inference of missing entities by better utilizing structural, textual, and visual information. Unlike previous diffusion-based methods that directly process raw multimodal features, MGDT employs a Relation-Adaptive Semantic Routing Mixture-of-Experts (RASR-MoE) module to filter irrelevant modality interference and select relation-relevant semantic paths. This is followed by a frozen Multimodal Large Language Model (MLLM) to align the routed representations into a unified latent space, reducing cross-modal semantic heterogeneity. Finally, a Knowledge Graph Diffusion Transformer (KGDT) performs graph-conditioned denoising to generate the missing entity representation, showing superior performance on benchmark datasets. AI
