社交网络中图像对情感影响的建模

Modeling Emotion Influence from Images in Social Networks

Xiaohui Wang, Jia Jia, Lianhong Cai, Jie Tang

摘要:

图像成为表达用户活动、意见和情感的重要和普遍的方式。在社交网络中,个人情绪可能会受到其他人的影响,特别是亲密的朋友。我们专注于了解用户如何将情感嵌入到他们上传到社交网站的图像中,以及社交影响力如何在改变用户情感方面发挥作用。我们首先验证了情感影响在图像网络中的存在性,然后提出了一个基于概率因子图的情感影响模型来回答“谁影响谁”的问题。采用Flickr上的真实网络作为实验数据,通过深入的数据分析,研究了模型中各因素的有效性。我们的实验还表明,我们的模型,通过纳入情感的影响,可以显着提高准确性(+5%)预测的图像情感。最后,通过一个案例分析,进一步验证了该模型的有效性。

英文摘要:

Images become an important and prevalent way to express users' activities, opinions and emotions. In a social network, individual emotions may be influenced by others, in particular by close friends. We focus on understanding how users embed emotions into the images they uploaded to the social websites and how social influence plays a role in changing users' emotions. We first verify the existence of emotion influence in the image networks, and then propose a probabilistic factor graph based emotion influence model to answer the questions of "who influences whom". Employing a real network from Flickr as experimental data, we study the effectiveness of factors in the proposed model with in-depth data analysis. Our experiments also show that our model, by incorporating the emotion influence, can significantly improve the accuracy (+5%) for predicting emotions from images. Finally, a case study is used as the anecdotal evidence to further demonstrate the effectiveness of the proposed model.
