Only publications classified as ��Article�� or ��Review�� are considered. Data is collected from Web of Science and InCites. Publications from different Web of Science categories are grouped into relevant Academic Subjects. (Read full Methodology)	Research Impact The Research Impact category includes Category Normalized Citation Impact (CNCI). Category Normalized Citation Impact (CNCI) is the ratio of the citations received by an institution's published papers to the average citations of papers in the same category, year, and type of journal publication within an Academic Subject during the period of 2020-2024. A CNCI value of 1 represents world-average performance. A CNCI below 1 indicates that the citation times of this group publications are lower than the average level, while a CNCI above 1 signifies that the paper��s citation performance exceeds the average level. Only publications classified as ��Article�� or ��Review�� are considered. Data is collected from InCites database.
