Introduction to SCI:
The American Science Citation Index (SCI) was founded by the institute for scientific information in Philadelphia in 1957, and it is a citation database created and published by institute for scientific information (ISI)1961+0.
SCI (Science Citation Index), EI (Engineering Index) and ISTP (Science and Technology Conference Index) are three world-famous retrieval systems for scientific documents, which are internationally recognized as the main retrieval tools for scientific statistics and scientific evaluation, among which SCI is the most important.
SCI scope:
SCI is an international index, including natural science, biology, medicine, agriculture, technology and behavioral science. , mainly based on basic science. The selected publications come from 94 categories, more than 40 countries and more than 50 languages. These countries mainly include the United States, Britain, the Netherlands, Germany, Russia, France, Japan, Canada and so on. , including a certain number of China publications.
Overall structure:
SCI is published six times a year, and now there are six volumes of A, B, C, D, E and F in each issue. Citation index The citation index of SCI consists of four parts: author citation index, group author citation index, anonymous citation index and patent citation index.
Scientific influence and advantages of SCI;
Scientific influence:
Scientific citation index is based on S.C.Bradford's theory of document dispersion and eugene garfield's theory of citation analysis, and evaluates academic journals and scientific research achievements in many aspects by counting the cited frequency of 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. Therefore, SCI is currently recognized as the most authoritative scientific and technological literature retrieval tool in the world.
Advantages:
The advantage of SCI is the citation function. Here, readers can quickly know whether an author's paper has been cited by others, and the development process of a subject can be understood through the number of citations. In addition, you can also learn the latest information about the development of science and technology through SCI. SCI also has the function of reflecting the quality and academic level of scientific papers.
These advantages are very helpful for scientific and technological workers to consult the latest literature, track the international academic frontier, establish scientific research projects and keep abreast of international trends in specific research projects.
