ESI comprehensively measures the scientific research level, academic reputation of institutions, academic influence of scientists and academic level of journals from all angles through six indicators, including the number of papers, frequency of cited papers, frequency of all cited papers, highly cited papers, hot papers and cutting-edge papers.
