KBQA: Learning Question Answering over QA Corpora and Knowledge Bases
Table 10: Results on the WEBQUESTIONS test set.
['system', 'P', 'P@1', 'R', 'F1']
Results on WEBQUESTIONS We compared KBQA with some state-of-the-art systems by precision@1 (p@1), precision (P), recall (R), and F1 score as computed by the official evaluation script. The “WebQuestions” data set still has many non-BFQs. The results again show that KBQA is excellent at BFQ (the high precision for BFQs). The lower F1 score is caused by the recall, that KBQA cannot answer non-BFQs.
