A Joint Model for Question Answering and Question Generation
Table 1: Model evaluation on question- and answer-generation.
['Models', '[ITALIC] Answer Generation F1', '[ITALIC] Answer Generation EM', '[ITALIC] Question Generation QAF1', '[ITALIC] Question Generation PPL', '[ITALIC] Question Generation BLEU4']
We see that A-gen performance improves significantly with the joint model: both F1 and EM increase by about 10 percentage points. Performance of q-gen worsens after joint training, but the decrease is relatively small. We thus consider the overall outcome to be positive.
