一种用于多模态情感分析的深层多层注意网络

A Deep Multi-Level Attentive network for Multimodal Sentiment Analysis

Ashima Yadav, Dinesh Kumar Vishwakarma

摘要:

多模态情感分析越来越受到人们的关注,具有广阔的应用前景。现有的方法集中在单一的模态,这无法捕捉多个模态的社交媒体内容。此外,在多模态学习中,大多数研究都集中在简单地将两种模态结合起来,而没有探讨它们之间复杂的关系。这导致多模态情感分类的性能不令人满意。受现状的启发,我们提出了一种深度多级注意网络,它利用图像和文本模态之间的相关性来改善多模态学习。具体来说,我们沿着空间和通道维度生成双注意视觉地图,以放大CNN的表示能力。然后,我们通过应用语义注意力提取与双注意视觉特征相关的文本特征,对图像区域和单词语义之间的相关性进行建模。最后,自我注意力自动提取情感丰富的多模态特征进行分类。在MVSA-Single、MVSA-Multiple、Flickr和Getty Images四个真实数据集上进行了广泛的评估,验证了该方法的优越性。

英文摘要:

Multimodal sentiment analysis has attracted increasing attention with broad application prospects. The existing methods focuses on single modality, which fails to capture the social media content for multiple modalities. Moreover, in multi-modal learning, most of the works have focused on simply combining the two modalities, without exploring the complicated correlations between them. This resulted in dissatisfying performance for multimodal sentiment classification. Motivated by the status quo, we propose a Deep Multi-Level Attentive network, which exploits the correlation between image and text modalities to improve multimodal learning. Specifically, we generate the bi-attentive visual map along the spatial and channel dimensions to magnify CNNs representation power. Then we model the correlation between the image regions and semantics of the word by extracting the textual features related to the bi-attentive visual features by applying semantic attention. Finally, self-attention is employed to automatically fetch the sentiment-rich multimodal features for the classification. We conduct extensive evaluations on four real-world datasets, namely, MVSA-Single, MVSA-Multiple, Flickr, and Getty Images, which verifies the superiority of our method.
