Large-scale vision–language models (LVLMs) have achieved remarkable progress on various reasoning tasks. However, most studies focus on natural photographic images and pay limited attention to multi-panel visual narratives such as comics. This leaves a clear gap in our understanding of how well LVLMs perform chronological reasoning across comic panels. To address this, we introduce **ChrOMIC**, a new benchmark dataset for **chro**nological reasoning in multi-panel **comic**s. It covers six types of reasoning questions and spans both Western and Japanese comic styles. To ensure high-quality annotations, we customized a human–AI collaborative annotation process tailored to the characteristics of the two comic styles. We further introduce three core tasks: Description Reordering and Panel Reordering, which jointly assess models’ ability to understand chronological order in panel sequences, and Multiple-Choice Question Answering (MCQA), which evaluates narrative-level reasoning. We evaluate a range of open-source and commercial LVLMs on ChrOMIC, and find that even the leading models struggle with panel-based chronological reasoning. Further analysis reveals key limitations, including weak visual action understanding and frequent hallucinations in fine-grained visual interpretation.

Sarcasm is a complex form of sentiment expression widely used in human daily life. Previous work primarily defines sarcasm as a form of verbal irony, which covers only a subset of real-world sarcastic expressions. However, sarcasm serves multifaceted functions and manifests itself through various rhetorical devices, such as echoic mention, rhetorical question and hyperbole. To fully capture its complexity, this paper investigates fine-grained sarcasm classification through the lens of rhetorical devices, and introduces RedSD, a RhEtorical Device-Aware Sarcasm Dataset with counterfactually augmented data.To construct the dataset, we extract sarcastic dialogues from situation comedies (i.e., sitcoms), and summarize nine rhetorical devices commonly employed in sarcasm. We then propose a rhetorical device-aware counterfactual data generation pipeline facilitated by both Large Language Models (LLMs) and human revision. Additionally, we propose duplex counterfactual augmentation that generates counterfactuals for both sarcastic and non-sarcastic dialogues, to further enhance the scale and diversity of the dataset.Experimental results on the dataset demonstrate that fine-tuned models exhibit a more balanced performance compared to zero-shot models, including GPT-3.5 and LLaMA 3.1, underscoring the importance of integrating various rhetorical devices in sarcasm detection. Our dataset is avaliable at https://github.com/qqHong73/RedSD.

Multimodal sentiment analysis identifies human emotional tendencies by analyzing text, visual, and auditory modalities. In most studies, the textual modality is usually considered to contain the most emotional information and is regarded as the dominant modality. Existing methods mostly map auxiliary modalities into a semantic space close to the dominant modality, which overly relies on the dominant modality. In this work, we propose a Feature Decomposition-Augmentation (FeaDA) framework, which aims to elevate the role of auxiliary modalities in multimodal data fusion. We first design a projector to decompose auxiliary modalities into partial features, which contain features for emotion judgment, and then utilize these decomposed features to guide the fusion process with KL loss, thereby enhancing the status of auxiliary modality fusion. To verify the effectiveness of our method, we conducted experiments on the CMU-MOSI, CMU-MOSEI, and CH-SIMS datasets. The experimental results show that our FeaDA framework outperforms mutilmodal sentiment analysis methods of the same type in main metrics.
