Altmetricsthe study and use of scholarly
impact measures based on activity in online tools and environments
Priem, J. (2014). Altmetrics. In Cronin, B. & Sugimoto, C.R. (Eds.). Beyond Bibliometrics: Harnessing MultidimensionalIndicators of Scholarly Impact. MIT Press, 2014.
“No one can read everything. We rely on filters to make sense of the scholarly literature, but the narrow, traditional filters are being swamped. However, the growth of new, online scholarly tools allows us to make new filters; these altmetrics reflect the broad, rapid impact of scholarship in this burgeoning ecosystem. We call for more tools and research based on altmetrics.”

“…altmetrics presents an alternative to the current practice of relying only on citation counts and journal impact factors for the quantitative analysis of impact by introducing new complementary approaches and sources of data.”

Altmetrics data providers
Altmetrics data providers
Including but not limited to:• Policy documents published online• Mainstream media (news sites)• Social reference managers (e.g., Mendeley, CiteULike)• Peer-review platforms (e.g., Publons, PubPeer, F1000)• Wikipedia• Blogs (curated list of scientific blogs)• Social media (e.g., Twitter, Facebook, Google+, LinkedIn)• Other sources such as YouTube, Reddit and Pinterest

Altmetrics are notlimited to scientificarticles and books
Altmetrics can reflect how researchers are engaging with the public
Altmetrics can reflect different types of impact and the context of the impact
Science
Education
Nature
Economy
Culture
Health
Society
Not just scientific impact…
Altmetrics canreflect different

Challengeswith altmetrics
The meaning and applicability of altmetrics generated on different platforms is still unclear
Lack of data standards leads to issues with transparency, replicability and accuracy
Question: Can we expect some common standards and/or tools for altmetrics to be provided at EU level?
doiDigital Object Identifier
Commonly known tracking issues; Most altmetrics identified from:
Altmetrics are time-dependent and thus comparing altmetrics of documents from different time periods should be avoided

Sciences and Technology. doi: 10.1002/asi.23101
(Some) Altmetrics only reflect the actions of those that actively use social media
Altmetrics may be skewed towards humorous and curious titles

Altmetrics are easily manipulated

Disciplinary differences in Twitter scholarly communication
Need for normalization

2) All altmetric research on Twitter
Mainly academics
Wider audience
1)
2)
- Mendeley readership and tweets reflect different things- They cannot be compared with each other without normalization

becomes the target, it ceases to be a

Stories behind the numbers
Mapping interactions, contexts and networks
“… instead of emulating the indicators used for scientific impact --based on outputs or citation approaches--, societal impact assessment should develop a different methodological approach --based on interaction approaches.”
