An evolving approach
Science-Metrix develops and employs methods that are at the frontier of bibliometrics. Using customized versions of several bibliometric databases, we apply best practices in scientometrics and technometrics, and contribute to the body of knowledge that determines what those best practices should be. As such, we know the limits of our methods and approach them critically.
In addition to publications and patent counts, our science and technology metrics draw on citation analysis, social network analysis and scale-free models. We are constantly improving our set of bibliometric indicators to best answer our clients’ needs.
Main bibliometric indicators
- Number of papers published in peer-reviewed journals or number of patents granted
- Growth: growth index or compound annual growth rate
- The average of relative impact factors (ARIF): an indicator of scientific impact measured at the journal level
- The average of relative citations (ARC): an indicator of scientific impact measured based on citations at the paper or patent level
- Specialization index (SI): an indicator of research intensity in a given field
- International collaboration rate, or collaboration index (CI): percentage of papers or patents with at least one co-author from abroad
- Inter-institutional collaboration rate: percentage of papers or patents with at least one co-author from another organization
- Collaboration networks that illustrate scientific collaboration patterns between countries, organizations or researchers
- Collaboration affinity: propensity of an entity to collaborate with another
