摘要:

本文解决了社交媒体上更真实场景下的假新闻检测问题。给定源短文本推文和相应的无文本评论的转推用户序列,我们的目标是预测源推文是否是假的,并通过突出可疑转推者及其关注的词的证据来产生解释。我们开发了一种新的神经网络为基础的模型,图形感知的协同注意力网络(GCAN),以实现这一目标。在真实的tweet数据集上进行的大量实验表明,GCAN的平均准确率可以显著超过最先进的方法16%。此外,案例研究也表明,GCAN可以产生合理的解释。

英文摘要:

This paper solves the fake news detection problem under a more realistic scenario on social media. Given the source short-text tweet and the corresponding sequence of retweet users without text comments, we aim at predicting whether the source tweet is fake or not, and generating explanation by highlighting the evidences on suspicious retweeters and the words they concern. We develop a novel neural network-based model, Graph-aware Co-Attention Networks (GCAN), to achieve the goal. Extensive experiments conducted on real tweet datasets exhibit that GCAN can significantly outperform state-of-the-art methods by 16% in accuracy on average. In addition, the case studies also show that GCAN can produce reasonable explanations.
