用多视角自编码器融合多种文本特征,提升假新闻识别准确率。
Multi-view autoencoders for Fake News Detection
- 通过多视角自编码器整合多种文本特征提取方法
- 相比单一特征,联合表示显著提升分类性能
- 精选部分视角可兼顾精度与计算效率,适合实际部署
由于假新闻在社交媒体上迅速传播,自动检测假新闻已成为关键任务。然而,该任务面临诸多挑战,尤其在于如何提取与假新闻相关的文本特征。研究表明,没有一种特征提取方法能在所有场景下始终优于其他方法。但不同方法可提供互补信息,有助于构建更全面的内容表征。本文提出使用多视角自编码器,将文献中常用的多种特征提取技术融合,生成用于假新闻检测的联合特征表示。在多个假新闻数据集上的实验表明,该方法相比单一视角的特征表示有显著性能提升。此外,我们发现选择部分视角而非全部组合,可在保持高准确率的同时降低计算开销。更多细节(含源码、图表和数据集)请见项目仓库:https://github.com/ingrydpereira/multiview-fake-news。
原文摘要 · Abstract (English)
Given the volume and speed at which fake news spreads across social media, automatic fake news detection has become a highly important task. However, this task presents several challenges, including extracting textual features that contain relevant information about fake news. Research about fake news detection shows that no single feature extraction technique consistently outperforms the others across all scenarios. Nevertheless, different feature extraction techniques can provide complementary information about the textual data and enable a more comprehensive representation of the content. This paper proposes using multi-view autoencoders to generate a joint feature representation for fake news detection by integrating several feature extraction techniques commonly used in the literature. Experiments on fake news datasets show a significant improvement in classification performance compared to individual views (feature representations). We also observed that selecting a subset of the views instead of composing a latent space with all the views can be advantageous in terms of accuracy and computational effort.
