Article output is counted in two ways:
- Count: a Count of one is assigned to an institution or country/region if one or more authors of the research article is from that institution or country/region, regardless of how many co-authors there are from outside that institution or country/region.
- Share: an institution’s or country/region’s Share for an article takes into account the percentage of authors from that institution or country/region and the number of affiliated institutions for the article. For calculation of the Share, all authors are deemed to have contributed equally to the article. The maximum combined Share for any article is 1.0.
The ratio of Count to Share gives an indication of the degree to which an institution or country/region collaborates in its research. Broadly speaking, if the Count is much higher than the Share it indicates a high degree of external collaboration and dependency on external resources. If the Count is close in value to the Share it indicates limited collaboration with external researchers and a strong dependency on internal resources.
