The Editors-in-Chief have retracted “A joint model for analyzing topic and sentiment dynamics from large-scale online news” [1] because the article shows significant overlap with a previously published article [2] without proper citation. Peng Liu, Jon Atle Gulla, and Lemei Zhang do not agree to this retraction.
