Collaboration calculates the number and percentage of outputs that have international, national or institutional co-authorship. The “Percentage” option should be used when comparing entities of different sizes, to normalise for this variable.
Collaboration Impact calculates the average citations received by the sets of outputs that have international, national or institutional co-authorship.
For publications with a combination of these levels of co-authorship, the higher collaboration type is assigned e.g. publications with:
- both national and international co-authorships are classified as international.
- authors who are not from the parent institution but within the parent institution’s country are classified as national.
In the calculation of Collaboration Impact, assignment of publications is based on the geographical location of the authors. This is independent of the geographical location of the authors from the citing papers.
Collaboration is useful to:
• Explore the extent of international and other types of collaboration within a set of publications.
• Benchmark the collaboration of entities of different sizes, but in similar disciplines.
Collaboration Impact is useful for demonstrating any benefits from establishing and maintaining collaborations to the citation impact of an entity's Scholarly Outputs.
