Ei is divided into periodical papers and conference papers. EI is an engineering index and the top three important information retrieval systems in the world, so EI is recognized in China. The retrieval system of EI periodical papers and EI conference papers is different, so the recognition degree is also different. Generally speaking, EI periodicals are recognized.
EI is the oldest comprehensive retrieval tool founded by American Institute of Engineers in 1884. EI enjoys a high reputation in the global academic, engineering and information fields, and is recognized as an important retrieval method in the field of science and technology.
EI periodical is a periodical searched by JA, and its level is higher than EI conference. EI periodical is recognized as the core periodical in the world. In China, some units will give authors who publish ei periodical papers 3000-8000 yuan. Moreover, EI periodicals are usually used for the promotion of masters, doctors, associate professors and professors.
There are also many periodicals included in ei in China. Journals that are both Chinese core journals and EI source journals are generally better than those that are only EI source journals. Of course, journals that are both Chinese core journals and EI source journals will be more difficult to publish, but at the same time, the recognition and value of articles are also high.
The papers collected by EI are divided into two levels.
1.EI Compendex index summary (also known as core data)
It mainly includes the title and abstract of the paper, indexing and deep processing with subject words and classification numbers. Whether there are subject words and classification numbers is the only sign to judge whether a paper is officially included in EI.
2. The header record on the first page of 2.EI (also called non-core data)
It is mainly reported in the form of title records. Some also have abstracts, but they have not been further processed, and there are no subject words and classification numbers. Therefore, the abstract on the first page is not necessarily a formal entry into EI.
Ei is a comprehensive information retrieval database of consulting literature in the field of engineering technology, which has high gold content and is biased towards mechanical engineering, electromechanical engineering, ship engineering, manufacturing technology and so on. When evaluating academic sub-majors or senior titles, 1-2 papers will be published in EI or SCI journals, which also reflects the academic level of the evaluation author. Generally speaking, people think that the number of periodical papers included in EI is relatively high.
EI, SCI and CPCI*** constitute three important paper retrieval systems in the world. The collection of international papers is a key index to assess state organs, scientific research units and award-winning units, and is generally used for the selection of master's and doctoral graduates, associate professors and full professors.
The difference between ei and sci
First, the nature is different.
1, SCI, the full name of which is Science Citation Index, is a world-famous periodical literature retrieval tool published in institute for scientific information, USA, and its source is selected through its strict selection criteria and evaluation procedures. Its retrieval object is mainly natural science.
2.EI is an engineering index, excluding basic theoretical research articles. It is a famous comprehensive retrieval tool for engineering technology published by American engineering information company.
Second, the fields involved are different.
The contents of periodicals collected by 1 and 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 and 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) publications are also included.
2. The fields involved in the 2.EI documents: mechanical engineering, electromechanical engineering, ship engineering, manufacturing technology, etc. Mining, metallurgy, material engineering, metal materials, non-ferrous metals, ceramics, plastics and polymer engineering. Civil engineering, building engineering, structural engineering, ocean engineering, water conservancy engineering, etc.
Third, establish differences.
1, SCI was founded by institute for scientific information, Philadelphia, USA. It is a citation database created and published by institute for scientific information (ISI) 196 1.
2.EI is the oldest large-scale comprehensive retrieval tool founded by the American Federation of Engineers in 1884.
