Challenge: Multimodal Dialogue Summarization (MDS) is a critical task with wide-ranging applications.
Approach: They propose a meta-evaluation benchmark for multimodal dialogue summarization based on image-sharing dialogues, corresponding summaries and human judgments .
Outcome: The proposed framework is the first to identify and formalize key evaluation dimensions specific to MDS.
