The essay reviews methods for analyzing sentiments tied to specific aspects or features of entities, such as product components. It introduces Aspect-Based Sentiment Classification (ABSC), a fine-grained approach to sentiment analysis that focuses on identifying and classifying sentiments about specific aspects. The paper categorizes ABSC models into three groups: knowledge-based models, machine learning models (including SVMs and deep learning), and hybrid approaches that combine both.The essay also discusses key challenges, such as handling implicit aspects, processing sentences with multiple aspects, and dealing with complex language structures. Recent advances in deep learning and transformer models are highlighted as major contributors to improving performance in ABSC tasks. Finally, the essay points to future directions, suggesting a focus on better aspect detection, handling implicit aspects more effectively, and improving the scalability of ABSC models.

这篇论文提出了一种基于超图的多模态情绪识别方法，旨在通过超图建立多模态数据之间的多元关系，提升情绪识别的准确性。该模型利用胶囊网络提取模态特征，超图卷积则用于学习模态间的关系，实现特征的有效融合。实验表明，该方法在情绪分类任务中表现优于传统二元关系图模型，特别是在处理未对齐的多模态数据时效果显著提升。

这篇文章总结了多模态情感分析的核心技术，介绍了面部表情、语音、文本等单模态情感识别方法，以及通过模态融合（特征级融合、决策级融合和混合融合）提高情感分析准确性的方法。文章还讨论了常用的数据集和目前面临的挑战，如数据集的局限、模态权重分配问题和算法复杂度。未来研究应着重于更大规模数据集的构建和优化融合算法。
