A Joint Model for Dropped Pronoun Recovery and Conversational Discourse Parsing in Chinese Conversational Speech

Jingxuan Yang, Kerui Xu, Jun Xu +5

In this paper, we present a neural model for joint dropped pronoun recovery (DPR) and conversational discourse parsing (CDP) in Chinese conversational speech. We show that DPR and…

Wasserstein Distance Regularized Sequence Representation for Text Matching in Asymmetrical Domains

Weijie Yu, Chen Xu, Jun Xu +4

One approach to matching texts from asymmetrical domains is projecting the input sequences into a common semantic space as feature vectors upon which the matching function can be r…
