A New Biomedical Passage Retrieval Framework for Laboratory Medicine: Leveraging Domain-specific Ontology, Multilevel PRF, and Negation Differential Weighting

<div>Effect of parameter values for GPRF-NEG in terms of P@1, P@3, and P@5. The best performances are achieved when (a) <i>m</i> = 35, (b) <i>λ</i> = 0.65, and (c) <i>γ</i> = 2.0.</div>
