摘要:

我们提出了事实新闻图(FANG),这是一种用于假新闻检测的新型图形化社会背景表示和学习框架。与以前的上下文模型有针对性的性能,我们的重点是表示学习。与转换模型相比,FANG在训练中是可扩展的,因为它不必维护所有节点,并且在推理时是有效的,而不需要重新处理整个图。我们的实验结果表明,FANG是更好地捕捉社会背景到一个高保真的表示,最近的图形和非图形模型相比。特别是,FANG对假新闻检测任务产生了显着的改进,并且在训练数据有限的情况下具有鲁棒性。我们进一步证明,方学到的表征概括到相关的任务,如预测的新闻媒体的报道的真实性。

英文摘要:

We propose Factual News Graph (FANG), a novel graphical social context representation and learning framework for fake news detection. Unlike previous contextual models that have targeted performance, our focus is on representation learning. Compared to transductive models, FANG is scalable in training as it does not have to maintain all nodes, and it is efficient at inference time, without the need to re-process the entire graph. Our experimental results show that FANG is better at capturing the social context into a high fidelity representation, compared to recent graphical and non-graphical models. In particular, FANG yields significant improvements for the task of fake news detection, and it is robust in the case of limited training data. We further demonstrate that the representations learned by FANG generalize to related tasks, such as predicting the factuality of reporting of a news medium.
