Article-level metrics for Cochrane Reviews
Wiley has partnered with Altmetric, a service that tracks and measures the impact of scholarly articles and datasets on both traditional and social media. Altmetric scores and badges are displayed on each Cochrane Review and Protocol published in the Cochrane Database of Systematic Reviews.
Altmetric tracks social media sites such as Twitter, Facebook, Google+, and Pinterest, as well as blogs, newspapers, magazines and online reference managers (e.g. Mendeley, CiteULike), for mentions of Cochrane Reviews. Altmetric creates and displays a score for each article measuring the quality and quantity of attention that the particular article has received.
The Altmetric score is based on three main factors: the number of people who have mentioned it online, the type of people who have mentioned it (i.e. scientists or members of the public), and where the mentions occurred.
The following symbol can be found next to each article (in this example, the article’s Altmetric score is currently 30):
You can click on the symbol for a breakdown of the Altmetric score. This will show you where and when the article was mentioned online. You can also view an explanation of how the score was calculated, compare it with other article’s scores, and see a breakdown of the demographics:
Because Altmetric tracks online activity based on DOI, scores will vary greatly between different versions of Cochrane Reviews. For a full picture of each article’s impact, please check the Altmetric scores for past versions as well as the most current version of each Cochrane Review.
While traditional metrics such as impact factor measure collections of articles (journals), Altmetric aims to provide an immediate benchmark for individual articles. The addition of Altmetric scores to the CDSR reflects the increasing use of social media to disseminate scholarly articles. Article-level metrics are emerging as important tools to quantify how individual articles are shared, used and discussed.
This score will be particularly useful in conjunction with more traditional means of measuring impact, such as citation data and impact factor, to create a more complete picture of an article’s impact.
