We observe that current dialogue summarization models have flaws that may not be well exposed by frequently used metrics such as ROUGE. In our paper, we 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. Some noteworthy trends which are different from the conventional summarization tasks are identified. We will release DialSummEval, a multi-faceted dataset of human judgments containing the outputs of 14 models on SAMSum. %R 10.18653/v1/2022.naacl-main.418 %U https://aclanthology.org/2022.naacl-main.418 %U https://doi.org/10.18653/v1/2022.naacl-main.418 %P 5693-5709
