Many of you will have heard the term Altmetrics – but what exactly do they measure? Unlike traditional metrics (e.g. Incites – JCR) which count the number of citations a journal receives, Altmetrics measures attention garnered by both traditional and new data sources. This includes mentions in news reports, blogs, academic social networks, social media, and reference software.

Publishers and institutions now often provide download and Altmetric counts – as can be seen by clicking on the links in the examples below. The first example displays monthly downloads of an article written by our own Dr Debra Carr. The other example shows the highest ranked article from Altmetrics Top 100 for 2016, written by a certain Barack Obama.

As with traditional metrics, controversy surrounds Altmetrics with claims of gaming (for example through ceaseless online self-promotion) and questions of legitimacy (does someone ‘sharing’ your work demonstrates a true measure of quality?). Altmetrics do not represent the quality of either the research or the researcher. They should be used in context with other metrics to provide a picture of the reach and influence of your work. Altmetrics help showcase if your research has been discussed by experts in your field, or if your data is referenced in a public policy.

Almetrics can also identify the platforms where research in your field gains the most attention. The places where your research will reach the most relevant audience.

The Altmetric attention score is automatically calculated by a weighted algorithm to reflect the overall reach and level of engagement. It is based on three main factors:

  1. The volume of the mentions (how many were there?)
  2. The source of the mentions (were they high-profile news stories, re-tweets, or perhaps a Wikipedia reference?)
  3. The author of the mentions (was it the journal publisher, or an influential academic?)

In order to limit gaming, social media posts are scored per user. So if the same user tweets about the same research multiple times, only the first tweet will count.

Below are a few links providing further information and guidance on Altmetrics. If you have any questions, your Library Information Specialist will be happy to help.
