AltmetricsThe 18th Nordic Workshop on Bibliometrics and Research Policy 2013

What is altmetrics?
• "Impact metrics, drawn from online sources"• "Social activity, component re-use, scholarly commentary,
scholarly activity, mass media mentions"• "Giving credit for other scholarly outputs than citations such as
datasets, software, and blog posts"• "A tool of discovery"
Article-level metrics (ALM) is altmetrics aggregated on article level

Current status
• Increased visibility on publishers' sites and at organizational repositories
• Core producers: Impact Story, Altmetric, Plum Analytics, PLOS ALMo With an ID, gather data from several dozen online serviceso Make comparisons to other articles by percentile of a reference
set from the same year (ImpactStory) and/or the same journal (Altmetric). Only PLOS makes field normalisation via its Relative Metrics (in beta)

Some research findings
• Moderate correlations between Mendeley readers and citation counts (eg Priem, Piwowar, Hemminger)
• Correlations between Twitter and citation counts low in biomedical papers, moderately negative among astrophysicists (Haustein et al)
• Postdocs and PhDs read more highly cited papers than professors do (Zahedi)
• F1000 recommendations not very good in predicting citations. Correlation exists, but is weak (Waltman, Costas)
• Data inconsistencies between different aggregators (Chamberlain)

Conclusions
Focus today? (eg Strasser)• Altmetrics as a component in the local repository• Altmetrics in researcher profiles: collect credit, pluggable to CRIS
Future? (Chamberlain)• We need improved data provenance with a trail back to the
source• One single impact score is appealing but does not put the impact
in context
