Large Knowledge Model (LKM) paper maps literature into reasoning graphs to form a Scientific Reasoning Landscape
The arXiv paper introduces the Large Knowledge Model (LKM), a corpus-scale scientific knowledge infrastructure that represents papers as source-grounded reasoning graphs and aligns questions, claims, and reasoning chains across works to form a three-part Scientific Reasoning Landscape (Question, Workflow, Evidence). The authors describe system design and evaluations showing that LKM retrieval, with a fixed answering model, improves accuracy by 9.30%, 4.20%, and 14.69% on ChemBench, PubMedQA, and SciBench respectively, and enables reasoning-aware search, evidence-grounded QA, comparative evidence analysis, and research planning.
