Vector search limitations in enterprise RAG and proposed solutions

By PulseAugur Editorial · [1 sources] ·

Vector search, commonly used in retrieval-augmented generation (RAG), struggles with multi-hop enterprise reasoning where answers depend on facts spread across multiple documents. While adding a knowledge graph can address this by linking entities and relationships, it introduces costs for extraction and entity resolution, and the graph's accuracy is limited by its stored data. The author suggests a hybrid approach, starting with vector search and only implementing a knowledge graph if necessary, after rigorous testing and piloting in specific domains. AI

IMPACT Highlights challenges in applying current RAG techniques to complex enterprise data, suggesting hybrid approaches for improved reasoning.

RANK_REASON The item discusses limitations and potential solutions for a specific AI technique (RAG) in an enterprise context, offering analysis rather than announcing a new development.

    The Polaroid Trap: Why Vector Search Fails at Multi-Hop Enterprise Reasoning

    <p>For multi-hop questions in enterprise RAG you've got two options, and they break in different places. Stay on plain vector retrieval and it works until the answer depends on a middle fact that doesn't sound like the question. Add a knowledge graph and you can follow that fact,…
