Scientific Citation Index is a citation database created by eugene garfield (1957) in institute for scientific information, Philadelphia, USA. SCI, EI and ISTP are three world-famous retrieval systems of scientific and technological documents, and they are the main retrieval tools for scientific statistics and scientific evaluation recognized internationally.
In February 2020, the Ministry of Education and the Ministry of Science and Technology issued "Several Opinions on Standardizing the Use of Relevant Indicators of SCI Papers in Colleges and Universities and Establishing Correct Evaluation Orientation". This document should break the "SCI supremacy" of papers, take this as a breakthrough, take practical measures with strong pertinence and operability, break the "paper-only theory" and establish a correct evaluation orientation.
Main impacts:
Scientific citation index is based on Bradford's theory of document dispersion law and Garfield's theory of citation analysis. It evaluates and studies academic journals and scientific research achievements in many aspects by counting the frequency of cited papers, so as to judge the performance of scientific research output of a country or region, scientific research units and individuals and reflect its international academic level.
With its unique citation approach and comprehensive scientific data, scientific citation index ranks journals and papers through the statistics of a large number of citations, and then obtains quantitative indicators such as impact factors, citation frequency and real-time index of a journal and paper in a certain discipline.
The high frequency of citation shows that this paper has a great influence in its research field and has attracted the attention of international peers with high academic level. Because the papers included in SCI are mainly in the basic research field of natural science, SCI indicators are mainly suitable for evaluating the achievements of basic research, and the main achievements of basic research are academic papers.
Therefore, how to evaluate the basic research results is often simplified as how to evaluate the influence of the contents contained in the paper on the progress of scientific knowledge.
