It is the abbreviation of American Science Citation Index. Its full name is Science Citation Index, which was created in 196 1. It was founded according to the citation thought put forward by modern information scientist Engene Garfield1953. Today Garfield is still one of the editors of SCI. SCI is published by ISI (institute for scientific information) and institute for scientific information, USA. It's bimonthly. In addition to publishing SCI, ISI also has an online database SCISEARCH. It also published the Index of Scientific and Technological Progress.
SCI is an international retrieval publication, 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 and Canada, as well as a certain number of China publications.
SCI's selection of periodicals is scientific. It adopts the method of citation data analysis and peer review, fully considers the academic value of journals, and selects more than 3,400 journals, including international important journals. The 800,000 papers it selected can be said to be the essence of various disciplines. Therefore, it has become an internationally recognized representative tool to reflect the research level of basic disciplines. The number of scientific papers collected is regarded as one of the indicators of a country's basic scientific research level and scientific and technological strength. SCI retrieval system has always been the focus of the world's academic circles, the focus of competition, and also the world-recognized source of literature statistics.
But as far as SCI is concerned, its most important function is to help scientific and technical personnel obtain the most needed literature information. This is also the main intention of editing the index of the Ministry. The biggest advantage of SCI is its citation function. Readers can quickly know whether an author's paper has been cited by others, and the development process of a discipline can be understood through the number of citations. In addition, you can also use SCI to get the latest information about the development of science and technology, such as: Do you have any comments on a topic? Whether a theory has been confirmed, whether a work has been expanded, whether a method has been improved, whether a formulation is established, whether a concept is innovative, and so on. Therefore, SCI also has the function of reflecting the quality and academic level of scientific papers.
These advantages of SCI 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 when studying specific topics.
Selected SCI papers
It has become an accepted fact that the selection of journals and papers polished by SCI papers is stricter than other publications. SCI collects different scientific papers from China every year. The reasons are quite complicated, including the laws of the development of language, politics, economy and science and technology, and the strict implementation of the standards for selecting journals and articles. SCI should enrich and adjust the number of publications used each year.
According to the investigation of relevant departments, the selection of SCI journals is mainly based on editing quality, citation index and expert evaluation, among which citation index is the most objective. According to statistics, the impact factors (i.e., the citation rate of periodical papers) of six Chinese periodicals included in 1995 were all less than 0.4, with an average of less than 0.23, while the average impact factor of more than 3,400 periodicals included in the same year was about 1, with the highest impact factor reaching 48.9. It can be seen that the citation index of China journals is far from the advanced level in the world, which is probably an important reason for the selection of China journals in SCI.
Facing the reality, we think we should pay attention to two aspects: First, strive to contribute to foreign countries. Although the selection of SCI is constantly changing, it still has its own core publications. According to the annual research report published by China Institute of Science and Technology Information (hereinafter referred to as CII) 196, the number of China papers and periodicals collected by196 has decreased, but the ranking has risen from 15 to 14. The increase is mainly due to the increase in the number of journals in which China's papers enter SCISEARCH. From the 8200 papers that entered the core circle of SCI, 9 1% were published in foreign journals, and only 9% were published in domestic journals. According to experts' analysis, there will be no greater breakthrough in the number of selected journals in China in a few years. Therefore, the more papers submitted, the greater the chance of being selected. Second, pay attention to the quality and standardization of the paper. According to the investigation results of Zhongxin Institute Information Analysis Center 1993, it is pointed out that the key to improve the selection rate lies in whether the content and academic level of the paper can attract enough attention from the other party. In addition, SCI attaches great importance to the standardization of the paper format, such as whether the title, author and institution name are clear, and whether the references are complete (including the author of the references, the title of the paper, the published periodicals and the year, volume, issue, page and number of publication, etc.). In short, for various reasons, we can't change the fact that we are chosen by others, but through unremitting efforts, it is still ourselves who dominate our destiny.
Engineering index
The EngineeringIndex (EI) was founded in 1884 and published by American Engineering Information Company, which reports periodicals, conference papers, scientific and technological reports and other documents in various disciplines of engineering technology.
ISTP
Scientific index &; Technical Proceedings (ISTP), also published by ISI, was founded in 1978, reporting the conference papers of the annual scientific and technological conferences held around the world. Edition (and name) publishing cycle, including literature sources, the printed version (ISTP) reports more than 4,700 kinds of conference proceedings every month, the optical version (ISTP) is updated quarterly, and more than 10000 kinds of conference proceedings are reported every year, and the online version (WOSP-S/T) is updated weekly, which is the same as the optical version.
SSCI
SSCI is the abbreviation of American social science citation index. Social Science Citation Index (SSCI) is a comprehensive social science literature database established in institute for scientific information, USA, 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.
CSCD
CSCD is the abbreviation of "Chinese Science Citation Database", and its disciplines include mathematics, physics, mechanics, chemistry, astronomy, earth science, biology, agriculture and forestry science, medicine and health, engineering technology, environment and management science. Source periodicals: 669 periodicals in the core library and 378 periodicals in the extended library. CD-ROM version of China Science Citation Database, CD-ROM version of China Science Metrology Index Database, and book version of China Science Metrology Index: Papers and Citation Statistics. CSCD, the core of China Academy of Sciences, cooperates with Thomson Reuters Technology Company. China Science Citation Database (CSCD) is the first non-English database on the ISI Knowledge Network (SCI) platform. The academic evaluation results of the Degree Center of the Ministry of Education in 2009 were announced, and the Chinese scientific citation database was designated as the query database. China Science Citation Database (CSCD) is divided into core database and extended database. After strict screening, the source periodicals of the core library are authoritative and representative core periodicals in various disciplines. The source journals of the extended database have also been extensively screened, and the winners are all excellent journals in various disciplines in China. In addition, China Science Citation Index Database (CSCD) is also the designated query database of academicians of China Academy of Sciences, the designated query database of National Natural Science Foundation for Distinguished Young Scholars, the designated query database of applicants for the 4th China Young Scientists Award, the designated query database of late performance evaluation of projects funded by National Natural Science Foundation of China, and the evaluation query database of State Key Laboratory of National Natural Science Foundation of China. From 2009 to 20 10, CSCD selected123 periodicals, including 67 in English and 0/056 in Chinese. There are 748 core journals and 375 extended journals. According to the latest collection report from 2009 to 20 10, CSCD has collected a variety of publications (core libraries).
Founded in 1989, China Science Citation Database contains more than 1000 Chinese and English scientific core journals and excellent journals published in the fields of mathematics, physics, chemistry, astronomy, geoscience, biology, agriculture and forestry, medicine and health, engineering technology, environmental science and management science. At present, from 1989 to now, there are 3 million papers, and the citation records are nearly 65438+. Chinese scientific citation database is known as "SCI of China".
CSSCI
CSSCI, an acronym for citation information of Chinese social sciences, is a landmark project successfully developed by Nanjing University in the field of humanities and social sciences evaluation in China. Scientific citation index reveals the internal relations between scientific documents from the mutual citation relationship between them. By searching and querying the scientific citation index database, we can reveal the process of application, improvement, development and revision of known theories and knowledge, and reveal the basic trend of subject research and development from an important aspect; Through the statistics and analysis of scientific citation index database, we can quantitatively evaluate the scientific research level of regions, institutions, disciplines and scholars, and provide first-hand information for the development and research of humanities and social sciences.
CSSCI follows the law of bibliometrics, adopts the method of combining quantitative and qualitative evaluation, and selects the journals with strong academic and standardized editing from the academic journals of humanities and social sciences in China as the source journals. The source journals or documents of CSSCI include not only China (mainland China, Hongkong, Macau and Taiwan Province Province), but also Chinese academic journals of humanities and social sciences published in Europe and America. The source journals are evaluated according to the standards of citation quantity, impact factors and expert opinions. In China, any official academic journal of humanities and social sciences with CN (China serial publication number) can participate in the selection. With the maturity of technical means, CSSCI will also pay attention to and collect academic achievements in the form of academic collections (continuous publications with official ISBN) in the future.
CSSCI has a national "CSSCI Advisory Committee" (renamed as "CSSCI Steering Committee" in 2005). The Committee is composed of 17 members and technical experts, including Peking University, Tsinghua University, Fudan University, China Renmin University, Beijing Normal University, Wuhan University, Nankai University, Jilin University, Sichuan University, Sun Yat-sen University, Shandong University, Xiamen University, East China Normal University, Central China Normal University, Wenzhou Normal University and Nanjing University. The Steering Committee is an academic decision-making body. Its main responsibilities are: to formulate and revise the articles of association of the steering Committee; Consider the long-term research and development plan of the center; The research and development of CSSCI system in the guidance center: a review of the source journals of China Social Science Citation Index; a review of the main news releases of CSSCI; Coordinate major national academic activities in the field of research and evaluation of humanities and social sciences in China.
At present, the Ministry of Education has regarded CSSCI data as an important indicator in the evaluation of colleges and bases, achievement awards, project establishment, evaluation of famous journals and personnel training. CSSCI database has been used by more than 65,438+000 units in Peking University, Tsinghua University, China Renmin University, Fudan University, National Library and China Academy of Sciences. , and as an important basis for the evaluation and review of regions, institutions, academics, disciplines, projects and achievements.
