使用动态传播结构增强社交媒体中的谣言检测

Enhancing Rumor Detection in Social Media Using Dynamic Propagation Structures

Shuai Wang, Qingchao Kong, Yuqi Wang, Lei Wang

摘要:

Facebook和Twitter等社交媒体已成为最重要的信息传播渠道之一。然而,这些社交媒体平台经常被滥用来传播谣言,这带来了严重的社会问题,因此,迫切需要自动谣言检测技术。现有的谣言检测工作更多地集中在文本特征的利用上,而扩散结构本身可以为谣言的识别提供关键的传播信息。以前的作品,考虑了结构信息,只利用有限的传播结构。此外,很少有相关的研究已经考虑了扩散结构的动态演化。为了解决这些问题,在本文中,我们提出了一种使用动态传播结构的神经模型(NM-DPS)用于社交媒体中的谣言检测。首先,我们提出了一个分区的方法来模拟传播结构的动态演变,然后使用基于时间注意力的神经模型来学习的动态结构的表示。最后,我们融合的结构表示和内容特征到一个统一的框架,有效的谣言检测。两个真实世界的社交媒体数据集上的实验结果表明,动态传播结构信息的显着性和我们所提出的方法在捕捉动态结构的有效性。

英文摘要:

Social media, such as Facebook and Twitter, has become one of the most important channels for information dissemination. However, these social media platforms are often misused to spread rumors, which has brought about severe social problems, and consequently, there are urgent needs for automatic rumor detection techniques. Existing work on rumor detection concentrates more on the utilization of textual features, but diffusion structure itself can provide critical propagating information in identifying rumors. Previous works which have considered structural information, only utilize limited propagation structures. Moreover, few related research has considered the dynamic evolution of diffusion structures. To address these issues, in this paper, we propose a Neural Model using Dynamic Propagation Structures (NM-DPS) for rumor detection in social media. Firstly, we propose a partition approach to model the dynamic evolution of propagation structure and then use temporal attention based neural model to learn a representation for the dynamic structure. Finally, we fuse the structure representation and content features into a unified framework for effective rumor detection. Experimental results on two real-world social media datasets demonstrate the salience of dynamic propagation structure information and the effectiveness of our proposed method in capturing the dynamic structure.
