MS-RAG: A Multimodal Retrieval-Augmented Framework for Digital Twins with Knowledge Graph Reasoning

2025

Traditional Retrieval-Augmented Generation (RAG) frameworks struggle to effectively handle multi-source heterogeneous data in digital twin scenarios, leading to insufficient accuracy in component relationship analysis and fault reasoning. This paper proposes a Multi-Stage Retrieval-Augmented Framework (MS-RAG), …
