In recent years, in the evaluation index of scientific research level and academic achievements of individuals or units, the number of papers published by individuals or group units in the three retrieval systems is the main evaluation index. So what are these three retrieval systems? How to improve the probability of individual published papers being collected by the three retrieval systems and the amount of groups collected by the three retrieval systems? 1 What are the three retrieval systems? The so-called three retrieval systems refer to Science Citation Index (SCI), Engineering Index (Ei) and Science and Technology Conference Proceedings (ISTP). Science CitationIndex— (SCI) is a comprehensive scientific and technological retrieval tool edited and published by institute for scientific information, Philadelphia, USA. Sci-tech periodicals mainly come from more than 40 countries such as the United States and Britain, and also include non-periodical documents, such as officially published conference proceedings, papers, monographs and books. There are few periodicals included in SCI in China, and 9 periodicals have been included by the end of 1997. They are China Science Series A, China Science Series B, China Science Series C, China Science Series D, China Science Series E, China Physics Express, Theoretical Physics Communication, Chinese Medical Journal and acta pharmacologica sinica. Except acta pharmacologica sinica, which is in Chinese, all the others are in English, which also shows that SCI is seriously biased in language. Engineering Index (Ei) is edited and published by American Engineering Information Company. It is a comprehensive retrieval tool in engineering technology. Ei has collected scientific and technological documents in 26 languages from more than 50 countries around the world. By the end of 2000, more than 0 kinds of China periodicals 100 have been collected. The Index of Scientific and Technological Progress (ISTP) was edited and published by institute for scientific information, USA. The collected conference papers involve engineering technology, applied science, life science, clinical medicine, physical chemistry, biology and environmental science. 2 How to be included in the three retrieval systems? 2. 1 In order to select a good topic, full investigation should be conducted before the project is established, among which literature investigation is a very important form of investigation. On the basis of full investigation, select the frontier topics in the subject field. The scale of the project is not necessarily large, but the research must be in-depth, the results must be profound, and there must be unique opinions. 2.2 The quality of the paper should be high. With high-level research results, it is necessary to write papers in time. The way of discussion, the choice of content, the elaboration of academic ideas and the introduction of research background of the paper should be carefully scrutinized and considered. It is necessary to make the paper short and pithy while being rigorous in structure, rich in content, complete in discussion and clear in organization. Words and illustrations are well matched. The style and format of papers should be standardized. Title, abstract, keywords, text and references are indispensable. The title of the paper should clearly describe the content of the article, and avoid being big and empty; It is necessary to give a clear, definite and concrete overview of the theme of the article, that is, the research object and its field, theoretical or experimental results, conclusions and other meaningful viewpoints, and avoid exaggeration and emptiness; Keywords should reflect the central theme of the paper, and try to use highly specific keywords; For those documents that can explain the research background and inspire the writing of the article during the research process, they should be listed in the references. 2.3 Papers should be published in Ei and SCI journals or important academic conferences. When you write a high-quality paper, you must publish it in Ei and SCI journals or important academic conferences sponsored by large academic groups, and publish the essays after the conference. At present, most Ei and SCI journals in China are marked on the cover (although some journals are marked as Ei and SCI journals, the number of journals is very small, or even not included for many years), and very few journals are not marked. Only when your paper is published in the sources of Ei and SCI can it be included in Ei and SCI. However, it needs to be clear that just because your paper is published in the sources of Ei and SCI does not mean that your paper must be included in Ei and SCI. Although publications are the sources of Ei and SCI, Ei and SCI do not collect all the above papers, but screen them. Therefore, English translation of titles, keywords and abstracts must be paid attention to, otherwise high-level papers will not be included in Ei and SCI (when a journal is marked as the source of Ei and SCI, but the published papers are not standardized in format, and there is no English translation of titles, authors' names, authors' units, keywords and abstracts, whether this journal is still the source of Ei and SCI deserves further verification). 2.4 How to improve the collection of group units in the three retrieval systems As employees of a group unit, we all hope that the ranking of this unit in the province and even the whole country can be continuously improved. Because the ranking is mainly based on the number of papers produced by the group units collected by the three retrieval systems, efforts should be made to increase the number of papers collected by the group units in the three retrieval systems. Therefore, when employees of a certain group publish papers, the English translation of the names of the group units should be unified. In any case, we must adhere to the right of authorship of the group unit and have the consciousness of the group unit. At present, due to the requirements of the reading unit, the authors of this group can only be signed in the name of the reading unit. At this time, although the author of the paper is an employee of a group unit, although the paper has been included in the three retrieval systems, it does not increase the amount of work units. How to deal with this problem, I think one way is to read the name of the work unit at the same time. If the reading unit doesn't agree with this method, you can add a person who has helped your research as the co-author of the paper, so that the name of your group unit appears in the signature of the group author unit of the paper. In addition, each unit can also introduce some high-level talents with high paper output, and their papers will be included in the three retrieval systems to improve the ranking of group units. To sum up, in order to improve the probability of personal papers being included in the three retrieval systems, papers should be published in the three retrieval journals or attend large academic conferences; In order to increase the number of group units in the three retrieval systems, the English translation forms of group units should be unified. How to judge whether a paper is really included in EI? At 22: 00 on May-13, 2009, some readers didn't choose the database when searching whether the papers were included in EI database, but just clicked on EI retrieval platform. If there is a result, they think that the article is included in the EI database, but it is not. Although there are retrieval results, they are not necessarily included in EI database, because there are two databases "Compendex" and "Inspec" on the retrieval platform of "Project Village". When searching, you should first select a database. If the retrieval paper is included in EI, you must select "Compendex". In addition, after expanding the retrieved results, you can also judge which database this article is included in. The difference is as follows: 1. EI inclusion: search for digits with serial number 1 1; Database: Compendex. 2.Inspec set: the retrieval serial number is 7 digits; The difference between the core part and the non-core part of the database: inspec.ei. In the search results, all three fields (1. Abstract 2.ei main title 3.ei classification code) are included as the core part. Otherwise, how can we judge whether an international conference has been included in the Page one section? You may have encountered such a situation: some international conferences explained the inclusion of EI, but it was not included in the end, which was extremely depressing. So how to judge whether an international conference will be included in EI? In addition to looking at the inclusion of this conference in the past, there are the following small experiences: First, look at the conference paper publishing house: the inclusion of conference EI has little or no relationship with the organizers. The first element is mainly implemented in the publishing unit of paper conference collection. According to the experience, the world famous publishing houses are listed as follows: 1, springer Press (Springer): 100% EI, 2, American Society of Mechanical Engineering Press (ASME): 100% EI, 3, American Society of Civil Engineering Press (ASCE):100. American Institute of Electronic and Electrical Engineering Computer Press (IEEE CS): 99% EI included 5. American Institute of Electronic and Electrical Engineering Press (IEEE): 90% After determining the first factor, please check the credibility of the president of the conference 1, international level. If the conference initiated by IEEE accounts for 565,438+0% of the registration fee, the registration fee for this kind of conference is more than 500 dollars. Please note that only one conference in China was initiated by IEEE in 2007, namely ICMA2007, and nothing else. At present, there is no conference initiated by IEEE in China in 2008. 2. Initiation of national-level societies: such as China Computer Federation, China Automation Society and china institute of communications, such as WCICA and CCC. 3. School-level leaders: The school-level leaders of China University have China characteristics (such as ICTE, etc. Convene an international conference as chairman. 4. Technical support from world-class societies: such as IEEE CS, IEEE, IET, ASME, ASCE, etc.
