“The Christmas tree is up in the Altmetric office and it’s Top 100 time again. We’ve queried the Altmetric database to find out which academic articles got the most attention from the mainstream media, blogs, Wikipedia and social networks, as well as amongst a more academic audience in post-publication peer-review forums and research highlights. Data was collected from the Altmetric database on November 16 2015 and a downloadable file can be found on figshare. News and comment pieces are excluded, as are articles that were published before November 2014. Remember, this list in no way reflects the quality (high or low) of the articles included; it just provides an indicator of what was widely discussed and shared online. The Altmetric donut images and scores displayed in this list were correct at the time of collection, and may have changed since due to new mentions being made or previous mentions being deleted by their author. More information on how the Altmetric score is calculated can be found on the Altmetric support site.”
