MetaphorVU: Towards Metaphorical Video Understanding

Hugging Face Daily Papers Papers

Summary

This paper introduces MetaphorVU-Bench, the first systematic benchmark for metaphorical video understanding, and proposes MetaphorBoost, an inference-time enhancement framework that improves cross-domain mapping in multimodal large language models.

Metaphorical videos are prevalent across various real-world scenarios to convey complex ideas, and understanding them typically requires high-order cognitive capabilities. The lack of systematic studies on metaphorical video understanding not only constrains the real-world applicability of MLLMs but also impedes the thorough assessment of their high-order cognitive capabilities. To bridge this gap, we propose MetaphorVU-Bench, the first systematic and comprehensive benchmark dedicated to metaphorical video understanding. Through experiments, we find current MLLMs struggle with accurate metaphorical video understanding, lagging far behind human level, primarily due to defective cross-domain mapping. Motivated by this finding, we construct a metaphor knowledge graph as mapping augmentation and propose MetaphorBoost, an inference-time enhancement framework achieving consistent performance improvement. Our benchmark, analysis, and method provide useful insights and a foundation for future research on advancing MLLMs.

Abstract

Current multimodal large language models struggle with metaphorical video understanding due to poor cross-domain mapping, prompting the development of a new benchmark and enhancement framework.

Metaphorical videos are prevalent across various real-world scenarios to convey complex ideas, and understanding them typically requires high-order cognitive capabilities. The lack of systematic studies onmetaphorical video understandingnot only constrains the real-world applicability of MLLMs but also impedes the thorough assessment of their high-order cognitive capabilities. To bridge this gap, we propose MetaphorVU-Bench, the first systematic and comprehensive benchmark dedicated tometaphorical video understanding. Through experiments, we find current MLLMs struggle with accuratemetaphorical video understanding, lagging far behind human level, primarily due to defectivecross-domain mapping. Motivated by this finding, we construct ametaphor knowledge graphas mapping augmentation and proposeMetaphorBoost, aninference-time enhancementframework achieving consistent performance improvement. Our benchmark, analysis, and method provide useful insights and a foundation for future research on advancing MLLMs.

Hugging Face Daily Papers

ViMU is the first benchmark designed to evaluate video understanding models' ability to interpret metaphorical, ironic, and social meanings beyond literal visual comprehension, using hint-free open-ended and multiple-choice questions.
