Challenge: Existing work on abstractive dialogue summarizations has focused on news summarizing but there is no such comprehensive dataset.
Approach: They propose to use a chat-dialogues corpus with abstractive dialogue summaries to generate a short version of text that covers the main points succinctly.
Outcome: The proposed dataset achieves higher ROUGE scores than the model-generated summaries of news, compared with human evaluators' judgement.

A Finer-grain Universal Dialogue Semantic Structures based Model For Abstractive Dialogue Summarization (2021.findings-emnlp)

Copied to clipboard

Challenge: Abstractive summarization models have achieved impressive results on document summarizing tasks, but their performance on dialogue modeling is poor due to the crude and straight methods for dialogue encoding.
Approach: They propose a model that leverages Finer-grain universal Dialogue semantic Structures to model dialogue and generate better summaries.
Outcome: The proposed model outperforms various dialogue summarization approaches and achieves state-of-the-art (SOTA) ROUGE results on a SAMsum dataset.
DialSummEval: Revisiting Summarization Evaluation for Dialogues (2022.naacl-main)

Challenge: Current models for dialogue summarization have flaws that may not be well exposed by frequently used metrics such as ROUGE.
Approach: They propose to re-evaluate 18 categories of metrics in terms of four dimensions: coherence, consistency, fluency and relevance, as well as a unified human evaluation of various models for the first time.
Outcome: The proposed dataset will be used to evaluate 18 categories of metrics in terms of coherence, consistency, fluency and relevance, and a unified human evaluation of various models for the first time.
