摘要:

自动检测社交媒体上的谣言已成为一项具有挑战性的任务。以往的研究主要集中在从会话线索中学习指示性线索来识别谣言信息。然而,这些方法只能从不同的角度对谣言会话线程进行建模,而不能很好地融合多视图特征。在本文中,我们提出了一种新的多视图融合框架谣言表示学习和分类。它基于图卷积网络(GCN)对多个视图进行编码,并利用卷积神经网络(CNN)捕获所有视图之间的一致性和互补性信息并将它们融合在一起。在两个公共数据集上的实验结果表明,我们的方法优于最先进的方法。

英文摘要:

Automatic detecting rumors on social media has become a challenging task. Previous studies focus on learning indicative clues from conversation threads for identifying rumorous information. However, these methods only model rumorous conversation threads from various views but fail to fuse multi-view features very well. In this paper, we propose a novel multi-view fusion framework for rumor representation learning and classification. It encodes the multiple views based on Graph Convolutional Networks (GCN), and leverages Convolutional Neural Networks (CNN) to capture the consistent and complementary information among all views and fuse them together. Experimental results on two public datasets demonstrate that our method outperforms state-of-the-art approaches.
