Fig. 3From: External features enriched model for biomedical question answeringBiomedical QA case study—answer extraction Heatmap. The left side is the result of our model (BioBERT plus NER, POS features based on Feature Fusion Module), and the right side is the result of the baseline (BioBERT) model. The darker the color, the more likely this location is predicted to be the answer boundaryBack to article page
