Altmetric employs an algorithm to assign each item an automatically calculated score. Based on the volume and source of attention an item has received, the score is intended to reflect the reach or popularity of the research output. A multicolored 'donut' visualization is also generated to provide a summary of the sources of the attention that an item has received (red for news, light blue for Twitter, etc.). Altmetric make the data available via the Altmetric Bookmarklet, a browser plugin, the Explorer platform, a cloud-hosted database, and
API. The sources include academic citations and academic platforms, patents, posts on
social media and
web forums,
Wikipedia articles, users on
Mendeley. Many publishers, including
John Wiley & Sons,
Taylor and Francis, The
JAMA Network and
Springer Nature embed the Altmetric 'Donut' Badges into their journal article and book pages to show the Altmetric score for individual items from within the publisher platform. At least one website,
OOIR, is specifically built around the showcase of scientific trends based on Altmetric Attention Scores. Even though there is no clear link between altmetric scores and societal impact, they can be used to predict future citation impact, and may be a target for manipulation. == See also ==
