The research paper "Recursive Ontological Refinement: Multi--Step Logical Deduction in RAG Systems" (arXiv:2607.01001), published on July 1, 2026, presents a significant advancement in multi--hop logical reasoning. Researchers from the University of Cambridge and Google DeepMind introduce "Recursive Ontological Refinement" (ROR), a framework designed to facilitate iterative symbolic validation during the retrieval process. The system utilizes a "Deductive Feedback Controller" to verify each inference step against a formal ontology, effectively mitigating logical inconsistencies and hallucinations in complex generative tasks.
