Query: Filling Conversation Ellipsis for Better Social Dialog Understanding   The phenomenon of ellipsis is prevalent in social conversations. Ellipsis
increases the difficulty of a series of downstream language understanding
tasks, such as dialog act prediction and semantic role labeling. We propose to
resolve ellipsis through automatic sentence completion to improve language
understanding. However, automatic ellipsis completion can result in output
which does not accurately reflect user intent. To address this issue, we
propose a method which considers both the original utterance that has ellipsis
and the automatically completed utterance in dialog act and semantic role
labeling tasks. Specifically, we first complete user utterances to resolve
ellipsis using an end-to-end pointer network model. We then train a prediction
model using both utterances containing ellipsis and our automatically completed
utterances. Finally, we combine the prediction results from these two
utterances using a selection model that is guided by expert knowledge. Our
approach improves dialog act prediction and semantic role labeling by 1.3% and
2.5% in F1 score respectively in social conversations. We also present an
open-domain human-machine conversation dataset with manually completed user
utterances and annotated semantic role labeling after manual completion.
