摘要:

我们提出了分层递归神经网络(HERO),通过学习其语言风格来预测假新闻,这是与真相区分开来,正如心理学理论所揭示的那样。我们首先生成新闻文档的层次语言树;通过这样做,我们将每个新闻文档的语言风格翻译成其作者的单词用法,以及这些单词如何递归地构造为短语、句子、段落,并最终构造为文档。通过将层次语言树与神经网络相结合,该方法通过捕获具有语言意义的局部序列和全局递归结构来学习和分类新闻文档的表示。这是第一个工作提供层次语言树和神经网络保存树的信息,我们最好的知识。基于公开真实世界数据集的实验结果表明,该方法的有效性,它可以优于国家的最先进的技术在分类短和长的新闻文件。我们还研究了假新闻和真实新闻的不同语言风格,并观察了假新闻的一些模式。代码和数据已经公开。

英文摘要:

We propose the hierarchical recursive neural network (HERO) to predict fake news by learning its linguistic style, which is distinguishable from the truth, as psychological theories reveal. We first generate the hierarchical linguistic tree of news documents; by doing so, we translate each news document's linguistic style into its writer's usage of words and how these words are recursively structured as phrases, sentences, paragraphs, and, ultimately, the document. By integrating the hierarchical linguistic tree with the neural network, the proposed method learns and classifies the representation of news documents by capturing their locally sequential and globally recursive structures that are linguistically meaningful. It is the first work offering the hierarchical linguistic tree and the neural network preserving the tree information to our best knowledge. Experimental results based on public real-world datasets demonstrate the proposed method's effectiveness, which can outperform state-of-the-art techniques in classifying short and long news documents. We also examine the differential linguistic style of fake news and the truth and observe some patterns of fake news. The code and data have been publicly available.
