Open science is
“the idea that scientific
knowledge of all kinds
should be openly shared
as early as is practical in
the discovery process.”
Nielsen, M. (2011). Definitions of Open Science? Okfn mailing list. https://lists.okfn.org/pipermail/open-
science/2011-July/000907.html. Retrieved on 13 January, 2015.

Altmetrics and
open science?

4.
Friesike and Schildhauer
(2015) suggest that wider
range of quantitative
indicators of a wider range of
impact can be incentivizing for
researchers to make their
research more accessible,
adopting the open science
ideology.

Research Organizations. Springer.

Altmetrics

6.
Altmetrics
Provide a more nuanced
image of the total impact
that research has made?

7.
How are altmetric events
distributed between articles
in open access journals and
other journals?

8.
Our preliminary results are
based on an analysis of how
almost 4 million altmetric events
are spread between articles in
open access journals (as listed by
DOAJ) and other journals.
Thank you Euan and Altmetric.com for sharing the data!

Figure 1. Differences between the average number of altmetric events for open access
articles and for paid articles. Higher positive values indicate an advantage for open access
articles; higher negative values indicate an advantage for paid articles.

10.
The results
• Twitter (and Facebook to lesser degree)
might be able to reflect the attention of a
wider public.
• Mendeley is used mainly by researchers.
• A great deal of Wikipedia articles are
written by researchers with paid access to
research articles (additional evidence of
the high quality of Wikipedia articles?).
