Summary

This paper investigates the use of webgraph and social media data in combating misinformation by focusing on the effectiveness of heterogeneous graph models. It demonstrates that these models, which integrate webgraph and social media context, outperform homogeneous approaches in classifying website credibility. The study introduces "dredge words," terms associated with unreliable domains on social media, and reveals their strong connection to fake news websites. The research highlights the importance of diverse user paths in accessing misinformation and the challenge of search engines returning conspiracy content even after debunking, emphasizing the need for proactive algorithmic moderation. A novel dataset of dredge words is created and made available for further research. The study contributes to understanding misinformation spread dynamics and suggests that combining webgraph and social media data can enhance early detection and classification of unreliable domains.
