When a question involves several linked concepts, the retrieved pieces often produce a disjointed answer. LightRAG (Guo et al., BUPT and University of Hong Kong) addresses this by building a knowledge graph at indexing time. Documents are split into chunks, an LLM… 2. **[AnyGraph: Graph Foundation Model in the Wild](https://md.research.elamur.ai/free/en/papers/xia-2026-anygraph-graph-foundation-model-wild/)** *(2026 · 3 citations)* Graph neural models usually need heavy fine-tuning for each new graph, and they transfer poorly when structure or node features change across domains. ## All works 8 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1.
