GraphRAG and Multimodal Knowledge Graphs: Research and Applications
From discovery in narrative text to image–text evidence fusion: when graph structure helps, how to test it, and how to apply it.

Original design
Connect knowledge.
Follow the evidence.
Anchored in Microsoft Research’s GraphRAG article and Meituan’s dish-graph article, the report combines papers and official sources to examine construction, retrieval, generation and multimodal alignment.
A critical narrative synthesis separates source-reported findings, proposed designs and toy experiments. Bibliographic records state reading scope. Costs are hypothetical; toy experiments do not reproduce model performance.
