Question Answering with Subgraph Embeddings
Table 3: Results on the WebQuestions test set.
['Method', 'P@1 (%)', 'F1 (Berant)', 'F1 (Yao)']
(p@1) of the first candidate entity (even when there are a set of correct answers), comparing to recently published systems. Our default approach uses the Subgraph representation for answers and C2 as the candidate answers set. Replacing C2 by C1 induces a large drop in performance because many questions do not have answers thatare directly connected to their inluded entity (not in C1). However, using all 2-hops connections as a candidate set is also detrimental, because the larger number of candidates confuses (and slows a lot) our ranking based inference.
