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.
