What is SCISSCICSSCI?

1. American Science Citation Index (SCI) was founded by institute for scientific information (ISI) on 1957 in Philadelphia, USA. 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.

2.(SSCI) Social Science Citation Index is a companion piece of SCI, which was also founded by institute for scientific information. It is a large-scale retrieval tool, which can be used to analyze the number of social science papers in different countries and regions.

3. Chinese social science citation index is called "Social Sciences Citation Index" in English, abbreviated as CSSCI.

The database developed by China Social Science Research and Evaluation Center of Nanjing University is used to retrieve the essays and literature citations in the field of social sciences in China, which is a landmark project in the field of humanities and social sciences evaluation in China.

Extended data:

1.SCI？ Founded in institute for scientific information, USA, it includes authors, titles, source journals, abstracts and keywords, which can not only evaluate the academic value of articles from the perspective of literature citation, but also quickly and conveniently establish a reference network for research topics.

SCI was established in 196 1. SCI (scientific citation index), EI (engineering index) and ISTP (scientific conference record index) are three world-famous scientific document retrieval systems, which are internationally recognized as the main retrieval tools for scientific statistics and scientific evaluation, among which SCI is the most important.

After 40 years of development and improvement, it has developed from a single printing type to a powerful electronic, integrated and networked large-scale multidisciplinary comprehensive retrieval system.

The theoretical basis of SCI is Bradford's literature diffusion law theory and Garfield's citation analysis theory. SCI evaluates and studies academic journals and scientific research achievements from various aspects by counting the frequency of cited papers, so as to judge the academic level of a country, a scientific research institution, an institution of higher learning, a journal and even a scientific researcher.

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.

Therefore, SCI is currently recognized as the most authoritative scientific and technological literature retrieval tool in the world.

The periodicals collected by SCI mainly involve basic scientific research fields such as mathematics, science, chemistry, agriculture, forestry, medicine and biology. The selected journals come from more than 40 countries with more than 50 languages, among which the main countries are the United States, Britain, the Netherlands, Germany, Russia, France, Japan and Canada, and some China (including Hong Kong, Macao and Taiwan) journals are also included.

The types of documents collected include: research papers, book reviews, special discussions, editorials, autobiographies, letters, etc.

1more than 300 journals were selected.

3.CSSCI？ The Citation Index of Chinese Social Sciences (CSSCI) was successfully developed by Nanjing University. It is a key research project of the State and the Ministry of Education, and it is used to retrieve cited papers and documents in the field of social sciences in China.

CSSCI follows the law of bibliometrics, adopts the method of combining quantitative and qualitative evaluation, and selects journals with strong academic and standardized editing from more than 2,700 Chinese academic journals of humanities and social sciences as source journals.

The Ministry of Education has regarded CSSCI data as an important assessment index for the evaluation institutions and bases, achievement awards, project establishment and personnel training of colleges and universities nationwide.

The literature collected by CSSCI comes from the source periodicals selected by China Social Science Research and Evaluation Center of Nanjing University according to the principles and methods of selecting periodicals determined by the Chinese Social Science Citation Index Steering Committee and approved by the Ministry of Education.

The source journals are determined according to the impact factors of journals, the total number of citations, and the opinions of experts in various disciplines.

After confirmation, relevant journals will be added, deleted and adjusted every year according to the quality of journals.

The CSSCI database has been purchased and used by more than 100 companies in Peking University, Tsinghua University, China Renmin University, Wuhan University, Jilin University, Shandong University and Nanjing University, and it serves as an important basis for evaluation and review of regions, institutions, academics, disciplines, titles, projects and achievements.

At present, there are more than 500 academic journals in 25 categories, including law, management, economy, history and politics.
