Abstract
En 中文
Multimodal Sentiment Analysis (MSA) aims to recognize and understand a speaker's sentiment state by integrating information from natural language, facial expressions, and voice, has gained much attention in recent years. However, modeling multimodal data poses two main challenges: 1) There are potential sentiment correlations between modalities and within contextual contexts, making it difficult to perform deep-level sentiment correlation mining and information fusion; 2) Sentiment information tends to be unevenly distributed across different modalities, posing challenges in fully leveraging information from each modality for collaborative learning. To address the above challenges, we propose CMLG based on correlation mining and label generation. This approach utilizes a Squeeze and Excitation Network (SEN) to recalibrate modality features and employs Transformer-based intra-modal and inter-modal feature extractors to mine the intrinsic connections between different modalities. In addition, we designed a Self-Supervised Label Generation Module (SLGM) that relies on the positive correlation between feature distances and label offsets to generate single-peak labels, and jointly train multi-peak and single-peak tasks to detect sentiment differences. Extensive experiments on three benchmark dataset (MOSI, MOSEI and SIMS) have shown that the above proposed method CMLG achieves excellent results.
