2604.01051 Topological RAG: Retrieving Comprehensive Knowledge Through Small World Entanglement
Current Retrieval-Augmented Generation (RAG) systems face a fundamental completeness-precision dilemma: vector-based approaches optimize for precise needle-in-haystack retrieval but sacrifice comprehensive context through isolated chunk retrieval, while knowledge graph systems aim for completeness but suffer from query specificity challenges and complex traversal overhead. We present **Topological RAG**, a graph-based architecture that reconstructs semantic "small worlds" through weighted multi-hop traversal, prioritizing comprehensive corpus coverage over retrieval speed.
