BioDivergence: A Benchmark and Evaluation Framework for Hidden Contextual Contradictions in Biomedical Abstracts

In three linesBioDivergence is a benchmark and evaluation framework for hidden contextual contradictions in biomedical abstracts. It proposes a six-class conflict taxonomy, a 13-axis divergence ontology, and four structured outputs per claim pair. The silver benchmark contains 11,865 claim pairs across five biomedical domains. Mistral-7B-Instruct-v0.3 achieves 0.5523 accuracy and 0.3894 contextual-F1.
