Traditional RAG can struggle with highly structured, human-defined knowledge systems.
Research (e.g., TREX) highlights that structuring knowledge as graphs facilitates better retrieval of contextual depth compared to traditional vector-based methods. eccentric_rag_2020_remaster
The field has moved beyond basic RAG, diversifying into hybrid retrievers, iterative retrieval loops, and graph-based retrieval systems. The 2020-2025 maturation of RAG technology shows a
The 2020-2025 maturation of RAG technology shows a distinct shift toward modular, graph-enabled, and interpretable systems. While initial RAG simply linked documents, the "remastered" approach focuses on navigating complex data structures to achieve trustworthy and accurate generative AI outputs. for RAG systems?

This report provides an overview of the landscape following its introduction in 2020, based on systematic literature reviews published through 2025. 1. Executive Summary: RAG Evolution (2020–2025)
The shift toward systems that refine queries iteratively allows for better handling of complex, multi-document synthesis tasks.
