Query: Can Question Rewriting Help Conversational Question Answering?   Question rewriting (QR) is a subtask of conversational question answering
(CQA) aiming to ease the challenges of understanding dependencies among
dialogue history by reformulating questions in a self-contained form. Despite
seeming plausible, little evidence is available to justify QR as a mitigation
method for CQA. To verify the effectiveness of QR in CQA, we investigate a
reinforcement learning approach that integrates QR and CQA tasks and does not
require corresponding QR datasets for targeted CQA. We find, however, that the
RL method is on par with the end-to-end baseline. We provide an analysis of the
failure and describe the difficulty of exploiting QR for CQA.
