Biomedical Question Answering via Weighted Neural Network Passage Retrieval
Table 1: Passage retrieval performance for biomedical question answering.
['Method', 'MAP', 'Precision', 'Recall', '[ITALIC] F1']
each at a cut-off rank of 10 retrieved passages. Statistical significance of method differences is determined using a Wilcoxon signed-rank test at α<0.05-level and significant improvements over all baselines are indicated with an asterisk. While questions were originally grouped in batches, here we forego this structure in the interest of brevity. Batch-level scores showed some variance but displayed the same relative method ranking as the aggregate overview.
