Deep Two-path Semi-supervised Learning for Fake News Detection
This addresses the challenge of timely fake news detection for social media users and platforms, but it is incremental as it builds on existing semi-supervised and deep learning methods.
The paper tackles the problem of detecting fake news on social media with limited labeled data by proposing a deep two-path semi-supervised learning model that combines supervised and unsupervised paths using convolutional neural networks, achieving effective recognition with very few labeled examples on Twitter datasets.
News in social media such as Twitter has been generated in high volume and speed. However, very few of them can be labeled (as fake or true news) in a short time. In order to achieve timely detection of fake news in social media, a novel deep two-path semi-supervised learning model is proposed, where one path is for supervised learning and the other is for unsupervised learning. These two paths implemented with convolutional neural networks are jointly optimized to enhance detection performance. In addition, we build a shared convolutional neural networks between these two paths to share the low level features. Experimental results using Twitter datasets show that the proposed model can recognize fake news effectively with very few labeled data.
