According to the test data provided in the article, Fast GraphRAG significantly outperforms the traditional VectorDB method in terms of query accuracy:
- 51 query tests: Fast GraphRAG accuracy of 961 TP3T, nearly 2x that of VectorDB (491 TP3T)
- 101 Query Tests: Fast GraphRAG accuracy of 931 TP3T, more than twice that of VectorDB (421 TP3T)
- Multi-hop query testing: Fast GraphRAG (95%) performed particularly well, nearly 3 times better than VectorDB (32%)
These advantages come mainly from the knowledge graph structure and PageRank algorithm employed by Fast GraphRAG, which enables it to better understand the complex relationships between data, thus improving retrieval quality and accuracy.
