In the ever-evolving landscape of academic research, collaboration is a key driver of scientific progress. To provide deeper insights into how different types of partnerships influence research impact, Clarivate, the mother company of Web of Science, has introduced a new suite of collaboration-related indicators in its InCites analytics platform. The key indicator is Collab-CNCI (Collaboration Category Normalized Citation Impact). 26 Mar 2025 [2 min read] |
Collab-CNCI builds upon the existing CNCI, which normalizes citation impact by subject, year, and document type, offering a baseline for comparison across diverse fields. By adding a fourth layer of normalization – collaboration type – Collab-CNCI allows users to compare the citation impact of different collaboration models more effectively. Each publication is categorized into one of five collaboration types, determined by the number of distinct countries in the author addresses or the number of organizations involved if all addresses are from the same country.
The collaboration types are defined as follows:
Understanding how these indicators interact is crucial. While CNCI tends to rise as international collaboration increases, Collab-CNCI helps distinguish whether higher impact stems from research quality or simply broader collaboration networks. Therefore, comparing the absolute values of CNCI against Collab-CNCI is not recommended. Instead, examining how each metric changes over time provides valuable insights into the dynamics of research impact. A general guideline is to use CNCI for broad comparisons across fields and countries, and Collab-CNCI for a more detailed and nuanced view of collaboration types.
