Abstract
A digital magazine server displays content items from various sources to users of client devices. Each source of a content item is identified by a domain, and content items for different sources have different domain-level quality. To differentiate sources of content items, the domains identifying the sources are ranked based on domain scores of the domains generated by an aggregate of multiple trained domain classifiers. A domain score of a domain indicates a domain-level quality of content items provided by a source identified by the domain. Each of the trained domain classifiers (e.g., a naïve Bayes classifier, a random forest classifier, and a logistic regression classifier) generates a prediction of whether a domain is a spam domain based on the domain features and domains with known labels. Based on the domain scores of domains, the domain ranking module may adaptively select content items from the sources with corresponding domains scores.
