Researchers have developed TIGRAG, a novel graph-augmented Retrieval-Augmented Generation (RAG) framework designed to improve multi-hop reasoning in Large Language Models (LLMs). Unlike previous methods that rely on expensive LLM pipelines for graph construction, TIGRAG utilizes a token co-occurrence knowledge graph built from sliding-window statistics, enabling scalable graph creation. This approach allows for efficient semantic expansion and iterative entity-driven retrieval, which has demonstrated superior performance on multi-hop Question Answering benchmarks compared to existing dense retrieval and graph-based RAG techniques. TIGRAG also significantly reduces indexing time, inference latency, and prompt footprint. AI
