SCI, EI, SSCI, A&HCI and ISTP are important retrieval systems in the world, and the status of papers collected by them is one of the important bases for evaluating and rewarding the achievements and levels of countries, units and researchers.
SCI (Science Citation Index), founded in 1963, is a world-famous periodical literature retrieval tool published by institute for scientific information (ISI). SCI contains about 3,500 core journals published all over the world in the fields of mathematics, science, chemistry, agriculture, forestry, medicine, life sciences, astronomy, geography, environment, materials and engineering technology. The extended edition includes more than 5800 periodicals. ISI selects journals through its strict standards and evaluation procedures, with a slight increase or decrease every year to ensure that its literature can fully cover the most important and influential research achievements in the world. SCI source journals are divided into two grades. 1)SCI, which is the core library of SCI with product code K (inner ring); 2)SCI-Expanded (SCI-E for short), also known as SCI-Rearch, is an extension library of SCI, and the product code is D (outer ring). Both the inner circle and the outer circle have choices, which are equally important, but there are some differences in influencing factors, geographical factors and discipline balance. Journals included in SCI Print (print edition), SCI-CDE (CD-ROM edition) and SCI-CDE with abstracts (CD-ROM edition with abstracts) are all in the inner circle. Journals included in SCI- Tape (Tape Database), SCI Search Online (Online Database) and Science Network (SCI Online Edition) are in the outer circle.
EI (Engineering Index), founded in 1884, is a famous comprehensive retrieval tool for engineering technology published by American Engineering Information Company. EI selects more than 2,000 engineering journals around the world. The collected literature covers almost all fields of engineering technology. Such as: electric power, electrician, electronics, automatic control, mining and metallurgy, metal technology, machinery manufacturing, civil engineering, water conservancy and so on. It has the characteristics of strong comprehensiveness, wide data sources, wide geographical coverage, large amount of reports, high quality of reports and strong authority. It mainly involves more than 3,500 kinds of scientific journals and 1 1,000 kinds of world publications, such as conference proceedings, papers, academic reports, scientific books, yearbooks and standards, with an annual report volume of 6,543.8+million. Ei divides the collected papers into two grades. Ei Compendex index summary. It includes the title, abstract, subject words and classification number of the paper for further processing; Whether there are subject words and classification numbers is the only sign to judge whether the paper is officially included in Ei. 2)Ei PageOne, which is not included in the abstract, has no subject words and classification numbers, and will not be further processed. Some PageOnes also have abstracts, but they have not been deeply processed, and there are no subject words and classification numbers.
SSCI (Social Science Citation Index) is a comprehensive social science literature database established by institute for scientific information (ISI), involving economics, law, management, psychology, regional studies, sociology, information science and so on. There are more than 700 important international journals in/kloc-0 in 50 languages, with about 3.5 million records. A&HCI (Art and Humanities Citation Index, Arts & amp； Citation index of humanities is a comprehensive literature database of arts and humanities of ISI, including language, literature, philosophy, Asian studies, history, art and so on. It has collected more than 1400 international authoritative journals, with a total of more than 2 million records.
ISTP (index of scientific conference proceedings &; Technical Proceedings) was founded in 1978 and edited and published by the American Society for Scientific Information. The proceedings include life science, physical and chemical science, agriculture, biology and environmental science, engineering technology and applied science, among which engineering technology and applied science literature account for about 35%.
Academic level is the foundation, format is the condition, and submission method is the key for papers to be included in retrieval systems such as SCI. No matter how high the academic level of the paper is, if the direction of submission is wrong, it will not be included in these retrieval systems at all.
In addition, ISI publishes JCR (Journal Citation Report) every year. JCR is an authoritative comprehensive database in the world. Its citation data comes from more than 7,000 journals of more than 3,000 publishing institutions around the world, and its professional scope includes science, technology and social sciences. JCR is the only comprehensive tool to evaluate journals in the world. It collects citation data of various professional journals all over the world, and shows the relationship between citation and cited. It can tell people which journals are the most influential, which are the most commonly used and which are the most popular. In addition to the influencing factors, it also gives the latest ranking, periodical abbreviation, International Uniform Number (ISSN), total citation, immediacy index, total number of articles, cited half-life, etc. After selecting the appropriate publication through JCR, readers can find the address or website information of the publication through the search engine, log on to the website of the publication and find online submission information.
