Multimodal Hyperbole Detection: Dataset and Study

Core Concepts
The author explores the importance of image modality in hyperbole detection and evaluates various fusion methods. Pre-trained multimodal models are found to be ineffective for this task.
The study introduces a new dataset for multimodal hyperbole detection, emphasizing the role of images in expressing hyperbole. Various fusion methods are evaluated, showing the significance of deep fusion for accurate detection. Pre-trained models like CLIP and BriVL perform poorly on this task. Cross-domain experiments highlight the challenges of generalization across different keywords. The analysis reveals that images play a crucial role in detecting hyperbole, with deep fusion methods outperforming shallow ones. However, common sense knowledge is essential for accurate detection. The study also addresses ethical considerations regarding potentially controversial content in the dataset.
The average text length of hyperbolic posts is significantly longer than non-hyperbolic ones. Top 10 words with high correlation to hyperbole include "death," "cold," and "fit." Only 15.8% of images in hyperbolic posts are themselves hyperbolic.
"Images mostly serve as assistants rather than express hyperbole themselves." "Introducing image modality together with text modality is useful for determining hyperbole." "Common sense knowledge is still helpful in easing problems faced by models."

How can common sense knowledge be effectively integrated into models for better performance

Common sense knowledge can be effectively integrated into models for better performance by incorporating external knowledge bases or ontologies that contain common-sense information. These sources can provide contextual understanding and background knowledge that the model may lack, especially in tasks like hyperbole detection where common sense plays a crucial role. Additionally, pre-training models on diverse datasets that include real-world scenarios can help imbue them with common-sense reasoning abilities. Techniques such as knowledge distillation from pretrained language models trained on general commonsense corpora like ConceptNet or integrating explicit rules based on common-sense reasoning principles can also enhance the model's performance.

What implications does the study have on understanding human expression through multimodal analysis

The study has significant implications for understanding human expression through multimodal analysis by showcasing how different modalities (text and image) work together to convey hyperbolic expressions. It highlights the complexity of human communication, where subtle cues from various modalities contribute to conveying exaggerated meanings effectively. Understanding these nuances is essential for developing AI systems capable of interpreting human emotions, intentions, and sentiments accurately across different modes of communication. By studying multimodal hyperbole detection, researchers gain insights into how humans combine textual and visual information to express complex ideas and emotions.

How can future research address the challenges of generalization in cross-domain multimodal tasks

Future research can address the challenges of generalization in cross-domain multimodal tasks by exploring techniques such as domain adaptation or transfer learning. Domain adaptation methods aim to adapt models trained on one domain to perform well on another related but distinct domain by minimizing distributional differences between domains during training. Transfer learning involves leveraging knowledge gained from one task or dataset to improve performance on a different but related task or dataset within a similar domain context. By incorporating these strategies along with data augmentation techniques specific to cross-domain scenarios, researchers can enhance model robustness and improve generalization capabilities across diverse domains in multimodal tasks like hyperbole detection.
