ESI ranking refers to the ranking of essential science indicators (ESI). Essential Science Indicators is an academic evaluation tool launched by Clarivate Analytics (formerly known as Thomson Reuters Intellectual Property and Science Department) to evaluate the influence and performance of global scientific research.
Essential science indicators (ESI) uses the data collected from the world's top journals and citation databases for quantitative analysis of academic research. It provides a large number of statistical data about academic papers, including citation frequency, research field of papers, authors and so on. These data can be used to evaluate the influence and performance of academic institutions, research fields and scientists.
In the indispensable scientific indicators, each field or discipline will be given a ranking, reflecting the international academic performance of this field or discipline. Ranking is calculated according to a series of indicators, including citation frequency, paper impact factors, paper citation time and so on. The higher the ranking, the higher the influence and performance of the field or discipline.
ESI ranking is widely used in academic circles, which provides objective indicators and data support for the evaluation of academic research. By looking at ESI rankings, scholars and academic institutions can understand their academic status in specific fields and the performance of other institutions and scholars. At the same time, government departments and academic institutions can also use ESI ranking to evaluate and compare the research performance of different fields and disciplines, and provide reference for the allocation of research funds and discipline construction.
It should be pointed out that ESI ranking is only an indicator, and it can't fully reflect all the performances of an academic institution or scholar. The influence and performance of academic research are influenced by many factors, including the popularity of research topics, the innovation of research methods and the influence of cooperative institutions. Therefore, when using ESI ranking, it is necessary to comprehensively consider other factors and make a comprehensive evaluation.
