Multi-Task Learning for Conversational Question Answering over a Large-Scale Knowledge Base
Table 10: Performance of IOB tagging and entity type prediction.
['IOB Tagging', 'Accuracy', 'Ours 0.9967', 'w/o Multi 0.9975']
And, although ∼ 0.002 performance reduction is observed for entity detection subtask, the performance of entity detection and linking is good enough for the downstream task, which thus poses a very minor effect on the performance of KB-QA.
