Researchers have developed RAGU, an open-source GraphRAG engine designed to improve the construction and retrieval of knowledge graphs for large language models. RAGU separates knowledge graph extraction from consolidation, employing a multi-stage process including typed extraction, deduplication, summarization, and community detection. A key innovation is Meno-Lite-0.1, a compact 7B parameter model optimized for language skills, which outperforms larger models like Qwen2.5-32B in knowledge graph construction and matches them in English GraphRAG tasks, all while running on a single GPU.
