What is it about?
The paper is about developing a machine-learning approach that can help fact-checkers direct their attention better and boost their productivity in examining low-credibility news sources. We examine a comprehensive list of possible signals for this task including textual features of content and the network of those sharing and receiving this content from their social network.

Why is it important?
Detecting fake news sources can help improve the coverage and efficiency of fact-checking efforts, which has important implications for both research and practice. Fact-checking is the foundation of much of the empirical research on fake news online, and it is at the heart of the many efforts by platforms to limit the spread of falsehoods online. Comprehensive and up-to-date lists of fake news sources are essential for getting an accurate read of the volume of misinformation circulating online and informing the public about it. Early detection methods are particularly important for making fact-checking efforts as relevant and effective as possible before falsehoods have circulated widely.
Perspectives
While we demonstrated that our approach can expand the coverage and improve the cost-effectiveness of fact-checking, it remains an open question of how this will be used in practice. There is also the question of whether social media platforms will continue to provide the necessary means in data access so others can continue this effort.
