DeepEra: A Deep Evidence Reranking Agent for Scientific Retrieval-Augmented Generated Question Answering
DeepEra is a novel agentic reranking framework designed to enhance scientific question answering (SciQA) by improving the selection and summarization of candidate evidence passages. It integrates step-by-step reasoning, semantic relevance, logical consistency, and evidential grounding to overcome the limitations of traditional embedding-based rerankers, which struggle with 'semantically similar but logically irrelevant' (SSLI) passages. DeepEra achieves significant improvements in retrieval robustness and answer accuracy on a new large-scale dataset, SciRAG-SSLI, providing a more reliable and interpretable solution for scientific RAG.

Addressing Semantically Similar but Logically Irrelevant (SSLI) Passages
Traditional RAG methods, relying on vector similarity, are prone to 'semantically similar but logically irrelevant' (SSLI) passages, leading to factual inaccuracies and amplified hallucinations. DeepEra explicitly tackles this by integrating step-by-step reasoning during reranking, allowing it to evaluate contexts based on logical consistency and evidential grounding, not just superficial semantic overlap. This is crucial for maintaining answer fidelity in scientific domains.
The introduction of the SciRAG-SSLI dataset, containing naturally retrieved contexts mixed with LLM-generated distractors, provides a robust benchmark to validate DeepEra's superior performance in these challenging scenarios, showcasing its logical robustness.
