Improving LLM Retrieval with GraphRAG-SF: Semantic Filtering for Graph-Based RAG Systems

Published in IEEE International Conference on Big Data (IEEE Big Data 2025), 2025

Graph-based Retrieval-Augmented Generation (RAG) systems enhance LLM responses by structuring knowledge as graphs. This paper introduces GraphRAG-SF, a semantic filtering approach that improves retrieval precision in graph-based RAG by filtering irrelevant subgraph traversals before they reach the LLM context window. Our method reduces noise in retrieved context while maintaining recall, leading to more accurate and grounded LLM responses.
