ESI(Essential Science Indicators) is an analytical database based on authoritative data of SCI (Science Citation Index) and SSCI (Social Science Citation Index), which aims to provide useful information such as the latest development, frontier trends and research hotspots of global scientific research. Specifically, ESI can provide the following information:

1. Discipline ranking: ESI can rank research institutions and scholars in different disciplines according to the citation times and influence of research papers, so as to understand the research level and influence in different fields.

2. Ranking of institutions and scholars: ESI can rank different research institutions and scholars according to the citation times and influence of research papers, so as to understand the research level and influence of different institutions and scholars.

3. Research hotspots and frontier trends: ESI can reveal the current research hotspots and frontier trends according to the cited times and subject words of the papers, so as to understand the research directions and future development trends in different fields.

4. Cooperation between scholars and institutions: ESI can analyze the cooperation between different institutions and scholars according to the author and institution information of the paper, so as to understand the cooperation relationship and research network between different institutions and scholars.

5. Influence and citation of academic achievements: ESI can evaluate the influence and citation of different academic achievements according to the citation times and influence of research papers, so as to understand the quality and influence of different research achievements.

Generally speaking, ESI provides a wealth of scientific research information and analysis tools, which can help researchers and science and technology managers understand the research status and trends in different fields, so as to make better scientific research plans and decisions.
