The Thomson Reuters’ Essential Science Indicators (ESI) has become a de facto analytical criterion for policymakers of academic-industrial communities to profile and benchmark primary research figures institutionally, since it was first established in 2001.
However, universal reliability and availability of the prevalent ESI-based metrics is conventionally understood as nominal rather than substantial yet, especially being used to assessment of individual scientific achievement (AISA). Sometimes, such empirical extrapolated theories based on sole and imperfect information source (Web of Science, WoS) always turns out knowledge illusions.
