Evaluative scientometrics:
Applied work at CWTS
2
To what degree does research evaluation
truly benefit from our work?
3
Do we fully exploit the possibilities of
scientometric analyses?
What should be the main focus of
research in evaluative scientometrics?
Trends in evaluative scientometrics
• Increasingly sophisticated indicators
• Do-it-yourself bibliometrics
• Informed peer review
• Altmetrics
4
Simple vs. advanced indicators
Simple indicators
• Low accuracy
• Easy to understand
• Limitations are evident
Advanced indicators
• High accuracy
• Hard to understand
• Limitations are hidden in
technical details
5
Dilemma of informed peer review
Domain experts
• Deep domain knowledge
• No scientometric
knowledge
Scientometricians
• Deep scientometric
knowledge
• No domain knowledge
6
How should these two groups communicate?
A common language is lacking
Dilemma of informed peer review
• Triangulation of expert knowledge and scientometric
indicators is difficult without a common language
• Scientometric indicators are either rejected or blindly
trusted
• Overemphasis on what can be quantified easily
7
Contextualized scientometric analysis
• Context
– Allow data underlying an indicator to be explored
• Simplicity
– Increased sophistication comes at a price; value simplicity
– Stop being overly negative about impact factors and h-indices
• Diversity
– To avoid overemphasizing what can be quantified easily, diversity of
indicators is essential
– Better to have indicators of low accuracy than no indicators at all

Advanced bibliometric indicators vs.
contextualized scientometric analysisAdvanced bibliometric
indicators
• Offer reasonably accurate
but incomplete
information
• Little room for deeper
understanding
• To be used for macro-
level evaluations
Contextualized
scientometric analysis
• Offers detailed
information requiring
careful interpretation
• Allows triangulating
expert knowledge and
indicators
• To be used for micro-level
and meso-level
evaluations
12
Conclusions
• Scientometricians should shift their attention from
advanced bibliometric indicators to contextualized
scientometric analysis
• New research questions:
– How to make contextual information available (e.g., interactive user
interfaces, visualizations)?
– How to guide domain experts in the use of this information?
– How to fulfill the promise of informed peer review?
