摘要: 近年来,用户在社交媒体上越来越多地使用多媒体内容来分享经历和表达情绪。相比单独的文本和图像,融合文本和图像的多媒体内容能够更为充分地揭示用户的真实情感。针对单一文本或图像的情感不明显问题,提出了一种基于卷积神经网络(CNN)的图文融合媒体的情感分析方法。该方法融合图像特征与三个不同级别(词语级、短语级和句子级)的文本特征构建CNN模型,以分析比较不同层次的语义特征对情感预测的影响。在真实数据集上的实验结果表明,通过捕捉文本情感特征和图像情感特征之间的内部联系,可以更准确地实现对图文融合媒体情感的预测。

Abstract: In recent years, more and more multimedia contents were used on social media to share users' experiences and emotions. Compared to single text or image, the complementation of text and image can further fully reveal the real emotion of users. Concerning the sentiment shortage of single text or image, a method based on Convolutional Neural Network (CNN) was proposed for multimedia sentiment analysis. In order to explore the influence of semantic representation in different level, image features were combined with different level (word-level, phrase-level and sentence-level) text features to construct CNN. The experimental results on two real-world datasets demonstrate that the proposed method gets more accurate prediction on multimedia sentiment analysis by capturing the internal relations between text and image.

Key words: social media, multimedia, sentiment analysis, Convolutional Neural Network(CNN)
