Abstract
Abstractive dialogue summarization is the task of capturing the highlights of a dialogue andrewriting them into a concise version. In this paper we present a novel multi-speaker dialogue summarizer to demonstrate how large-scale commonsense knowledge can facilitate dialogue un-derstanding and summary generation. In detail we consider utterance and commonsense knowl-edge as two different types of data and design a Dialogue Heterogeneous Graph Network (D-HGN) for modeling both information. Meanwhile we also add speakers as heterogeneous nodes to facilitate information flow. Experimental results on the SAMSum dataset show that our modelcan outperform various methods. We also conduct zero-shot setting experiments on the Argu-mentative Dialogue Summary Corpus the results show that our model can better generalized tothe new domain.- Anthology ID:
