Although the main objective of the Web of Science is intended to aid researchers to retrieve information, it is also commonly used as a research evaluation tool.
Count Papers measure productivity
Count Citations measure utility and influence
Based on the concept that if an article is cited it is an influential paper, or has had an impact upon the research community.
This concept can be extended beyond individual articles and used to evaluate:
Authors – Countries and geographic regions
Topics – Institutions
