1. Altmetrics, another view on impact
Wouter Gerritsma, January 2015

2. Altmetrics?
 New suit of metrics introduced by Priem et al. 2010
http://altmetrics.org/manifesto/
● A better filter and an alternative to citations and
peer review
 Other terms:
● Article level metrics
● Influmetrics
● Social media metrics
● Alternative metrics

3. Article level metrics?

4. Altmetrics promises
 A proxy for scientific impact
● More timely than citations
 Broader impact than measured by citations only
● Societal impact
 Impact of more varied outputs
● Capturing impacts of other publication types
● Measuring other scientific outputs (data sets, ELN,
code)
● Measuring other forms of influence (press, blogs,
twitter etc.)

5. Citations are only a tiny fraction of article
usage
