Self-Attention for Incomplete Utterance Rewriting

no code implementations24 Feb 2022 Yong Zhang, Zhitao Li, Jianzong Wang, Ning Cheng, Jing Xiao

In this paper, we propose a novel method by directly extracting the coreference and omission relationship from the self-attention weight matrix of the transformer instead of word embeddings and edit the original text accordingly to generate the complete utterance.
