Researchers have introduced REPAIR, a novel data augmentation framework designed to improve the accuracy of scientific information retrieval systems. This self-evolving framework addresses challenges posed by long-tailed concepts and fact-sensitive corpora, which often hinder dense retrievers and LLM augmentations. REPAIR iteratively generates training data by identifying knowledge gaps, expanding evidence using APIs, and differentiating through hard negative mining, thereby grounding retrieval in factual reality. Experiments show REPAIR significantly outperforms 19 existing baselines across nine materials science and biomedical benchmarks, underscoring the importance of factually augmenting data for robust scientific retrieval.
