What are altmetrics?

Communication between researchers◦ Research publications◦ Citations
Scholarly communication 1

”Societal impact” – broader, more diffuse than ”scholarly impact”
Distinction between impacts is central to altmetrics
A new impact

How do you count downloads? Is a tweet always a good thing? How sure are we of e.g. ”members of the
public”?
Data quality
![Page 16: Altmetrics – an alternative to traditional research indicators](https://reader035.fdocuments.us/reader035/viewer/2022062617/54c633c54a7959e43f8b4597/html5/thumbnails/16.jpg)
Different types of tweets?◦ Different degrees of impact?
What does a download mean? What does it mean to be a ”reader”?
Theoretical issues 1
![Page 17: Altmetrics – an alternative to traditional research indicators](https://reader035.fdocuments.us/reader035/viewer/2022062617/54c633c54a7959e43f8b4597/html5/thumbnails/17.jpg)
References can (probably) be aggregated to citations, especially for large units (macro-analysis)
Is this transferable to altmetrics?
Theoretical issues 2
![Page 18: Altmetrics – an alternative to traditional research indicators](https://reader035.fdocuments.us/reader035/viewer/2022062617/54c633c54a7959e43f8b4597/html5/thumbnails/18.jpg)
Large amounts of data available◦ Potential for macroscopic analyses
Usage of altmetrics is primarily local◦ Micro- or mesoscopic analyses
Status

Aggregates of altmetrics data◦ University analyses etc.◦ Potential for indicators
From micro to macro

Paul Wouters distinguishes between:◦ Theories of citations, references, indicators
Is there an equivalent approach to usage and social data?◦ How can we move from individual tweets to
theories of their meaning? Especially the meaning of multiple tweets.
◦ How about readership and downloads?◦ What type of meaningful indicators could be
constructed from this?
A theory of altmetrics?
