To reduce hallucination rates and overcome the limitations of static, outdated knowledge within parametric-only models.
Research (e.g., TREX) highlights that structuring knowledge as graphs facilitates better retrieval of contextual depth compared to traditional vector-based methods.
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)
Traditional RAG can struggle with highly structured, human-defined knowledge systems.
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? Specific use cases (like RAG in healthcare or finance)?
