AI总结:

针对现有研究对图像深层语义探究不足的问题,提出综合基准DEEPEVAL,评估发现现有大语言多模态模型的深层语义理解能力远落后于人类,且性能随语义维度变化,凸显了相关开发的根本性挑战。

摘要:

在社交媒体主导的时代,理解图像的深层语义至关重要。然而,当前研究主要聚焦于图像的表层描述,对其内在深层语义的系统性探究存在显著不足。本研究提出DEEPEVAL(深层语义评估基准),这是一个用于评估大语言多模态模型(LMMs)视觉深层语义能力的综合基准。DEEPEVAL包含人工标注的数据集以及三个递进式子任务:细粒度描述选择、深度标题匹配和深层语义理解。借助DEEPEVAL,我们评估了9个开源LMM和GPT-4V(ision)。评估结果表明,现有LMM的深层语义理解能力与人类之间存在巨大差距。例如,GPT-4V在深层语义理解方面落后人类30%,尽管它在图像描述任务上达到了与人类相当的性能。进一步分析显示,LMM在DEEPEVAL上的表现随所探究的深层语义具体维度的不同而变化,这表明开发LMM仍存在根本性挑战。

英文摘要:

Understanding the deep semantics of images is essential in the era dominated by social media. However, current research works primarily on the superficial description of images, revealing a notable deficiency in the systematic investigation of the inherent deep semantics. In this work, we introduce DEEPEVAL, a comprehensive benchmark to assess Large Multimodal Models' (LMMs) capacities of visual deep semantics. DEEPEVAL includes human-annotated dataset and three progressive subtasks: fine-grained description selection, in-depth title matching, and deep semantics understanding. Utilizing DEEPEVAL, we evaluate 9 open-source LMMs and GPT-4V(ision). Our evaluation demonstrates a substantial gap between the deep semantic comprehension capabilities of existing LMMs and humans. For example, GPT-4V is 30% behind humans in understanding deep semantics, even though it achieves human-comparable performance in image description. Further analysis reveals that LMM performance on DEEPEVAL varies according to the specific facets of deep semantics explored, indicating the fundamental challenges remaining in developing LMMs.
