Since DeepNews does not own the rights to the articles, an article is displayed within a so-called i-frame, just as it is in a browser. The display is determined solely by the newspaper in which the article appeared.
On a separate note, we have decided not to offer the Reader view provided by Safari, as this would 'take away' from publishers' ad traffic.
In the sorting, the novelty, the quality of an article (focus-ness, click-bait score, ...) and the similarity to the representing article with the same weight essentially go into it.
Currently, DeepNews only defines the political bias for articles from the Anglo-American region. As a basis for this, we use the left/right assessments of 'allsides.com', an independent NGO.
Unfortunately, so far such a list is not reliably available for German sources.
DeepNews matches all the people, companies, and places appearing in an article to the current, language-matching Wikipedia.
