摘要:

随着社交网络的发展,出于各种商业和政治目的的假新闻大量出现并在网络世界中蔓延。有了欺骗性的话,人们很容易被假新闻感染,并且会在没有任何事实核查的情况下分享它们。例如,在2016年美国总统大选期间,有关候选人的各种假新闻通过官方新闻媒体和在线社交网络广泛传播。这些假新闻通常是为了诽谤对手或支持他们一边的候选人而发布的。假新闻中的错误信息通常是为了激发选民的非理性情绪和热情而撰写的。这类假新闻有时会带来毁灭性的影响,而提高在线社交网络可信度的一个重要目标就是及时识别假新闻。在本文中,我们提出研究假新闻检测问题。自动识别假新闻是非常困难的,因为基于纯模型的新闻事实核查仍然是一个开放的问题,并且很少有现有的模型可以应用于解决这个问题。通过对假新闻数据的深入研究,从假新闻中使用的文字和图像中识别出了许多有用的显式特征。除了显式特征外,假新闻中使用的文字和图像中还存在一些隐藏的模式,这些模式可以通过我们模型中的多个卷积层提取的一组潜在特征来捕获。本文提出了一种基于文本和图像信息的卷积神经网络模型。通过将显式和潜在特征投影到统一的特征空间中,TI-CNN同时使用文本和图像信息进行训练。在真实世界的假新闻数据集上进行的大量实验证明了TI-CNN的有效性。

英文摘要:

With the development of social networks, fake news for various commercial and political purposes has been appearing in large numbers and gotten widespread in the online world. With deceptive words, people can get infected by the fake news very easily and will share them without any fact-checking. For instance, during the 2016 US president election, various kinds of fake news about the candidates widely spread through both official news media and the online social networks. These fake news is usually released to either smear the opponents or support the candidate on their side. The erroneous information in the fake news is usually written to motivate the voters' irrational emotion and enthusiasm. Such kinds of fake news sometimes can bring about devastating effects, and an important goal in improving the credibility of online social networks is to identify the fake news timely. In this paper, we propose to study the fake news detection problem. Automatic fake news identification is extremely hard, since pure model based fact-checking for news is still an open problem, and few existing models can be applied to solve the problem. With a thorough investigation of a fake news data, lots of useful explicit features are identified from both the text words and images used in the fake news. Besides the explicit features, there also exist some hidden patterns in the words and images used in fake news, which can be captured with a set of latent features extracted via the multiple convolutional layers in our model. A model named as TI-CNN (Text and Image information based Convolutinal Neural Network) is proposed in this paper. By projecting the explicit and latent features into a unified feature space, TI-CNN is trained with both the text and image information simultaneously. Extensive experiments carried on the real-world fake news datasets have demonstrate the effectiveness of TI-CNN.
