A Survey on Dialogue Summarization: Recent Advances and New Frontiers
share
With the development of dialogue systems and natural language generation techniques, the resurgence of dialogue summarization has attracted significant research attentions, which aims to condense the original dialogue into a shorter version covering salient information. However, there remains a lack of comprehensive survey for this task. To this end, we take the first step and present a thorough review of this research field. In detail, we provide an overview of publicly available research datasets, summarize existing works according to the domain of input dialogue as well as organize leaderboards under unified metrics. Furthermore, we discuss some future directions and give our thoughts. We hope that this first survey of dialogue summarization can provide the community with a quick access and a general picture to this task and motivate future researches.
