Abstract: This disclosure relates to methods and systems to generate information about news source items from a corpus of news sources, where identified news source items describe or are associated with a news event or topic of interest. The generated information can be presented as collections of news source items describing a news event or topic in, e.g., a newsfeed format, a report, a dashboard configuration, or for use in machine learning processes. News sources can be associated with a rating. The news source items, news sources, and collections can be analyzed to generate information including differences in coverage of generated or selected news events or topics according to various considerations, such as news source characteristics (e.g., bias/skew/viewpoint rating, age, location of news source or event, etc.), time, and presence, absence, or frequency of news sources ratings in a collection of news source items describing the news event or topic.
