Improving Question Answering over Incomplete KBswith Knowledge-Aware Reader
Table 2: Ablation on dev under the 30% KB setting.
['[BOLD] Model', '[BOLD] Hit@1', '[BOLD] F1']
S4SS2SSS0Px1 Ablation Study We see that both query reformulation and knowledge enhancement are essential to the performance. When replacing it with a standard gate function (see the row w/o conditional knowledge gate), the performance is even lower than the reader without knowledge enhancement, suggesting our proposed new gate function is crucial for the success of knowledge-aware text reading. The potential reason is that without the question information, the gating mechanism might introduce some irrelevant and misleading knowledge.
