Collab-CNCI

Collab-CNCI compares citation impact to global expected citations, normalized by subject, year, document type and collaboration type. Each publication falls into one of five collaboration types, determined by:

1. The number of distinct countries in the author addresses
2. If all addresses are from the same country, the number of organizations involved
   

Overview of Collaboration types

1. Domestic – Single: publications where all authors are affiliated with the same institution in a single country.
   • More formally, all author addresses share the same country and are affiliated with the same institution
   • Both unified and non-unified organizations are considered:
     1. If an organization is non-unified, the published name from the address is used.
     2. If an address is resolved, the unified organization name is used.
     3. If an address resolves to multiple unified organizations with a parent-child relationship, only the child organizations are counted.
2. Domestic – Multiple: Publications where all authors are affiliated with multiple institutions within the same country.
3. International – Bilateral: Publications with author addresses from exactly two distinct countries.
4. International – Trilateral: Publications with author addresses from exactly three distinct countries.
5. International – Quadrilateral +: Publications with author addresses from four or more distinct countries.
