VIP search term: any field, title or keyword, keyword, publication name, author, first author, institution, title, abstract, classification number, author profile, fund support and column information.
CNKI retrieval items: title, subject, abstract, key words, full text, author, first author, author unit, source, references and fund.
Question 2: What are the three famous search agencies? There are also three search websites.
Scientific citation index "scientific citation index"
Ei- engineering index "engineering index"
ISTP science and technology index; Index of scientific papers
Introduction to SCI
SCI is a scientific citation index created by institute for scientific information, USA. It contains literature works, 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. 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. -
SCI is divided into SCI and SCI-E according to the number of source journals. SCI refers to SCI print edition and SCI CD-ROM edition (SCI CDE), with more than 3,500 source periodicals. SCI-E(SCI extended) is an extended library of SCI, which contains more than 5,600 source periodicals and can be searched online or on the Internet. SCI covers more than 100 disciplines, mainly involving agriculture, biology and environmental science; Engineering technology and applied science; Medicine and life sciences; Physics and chemistry; Behavioral science.
Introduction to EI
EI is the abbreviation of engineering index. EI was founded in 1884 and published by engineering information company. EI is a comprehensive retrieval tool in the field of engineering technology, covering such disciplines as electric power, automatic control, power, machinery, instrumentation, material science, agriculture, bioengineering, mathematics, medicine, chemical engineering, food, computer, energy, geology and environment.
Introduction to ISTP
ISTP is an index of science. The abbreviation of Technical Proceedings is one of the two databases (ISTP and ISSHP) on the website of Scientific Proceedings in institute for scientific information, USA. Specialized in collecting conference documents of various important international natural science and technology conferences, including general conferences, symposiums, research conferences, seminars, conferences, etc. The subjects involved are basically the same as SCI.
The three major searches are not websites. They don't have websites.
Question 3: What does retrieval mean? Information retrieval refers to the process of organizing and storing information in a certain way and finding out relevant information according to the needs of information users, so its full name is also called "information storage and retrieval", which is information retrieval in a broad sense.
Narrow information retrieval only refers to the second half of the process, that is, the process of finding the needed information from information, which is equivalent to what people usually call information search.
Question 4: How does istp retrieve ISTP? I believe this is a problem that every author will encounter for the first time. Liang Xiao will give you a detailed introduction below:
ISTP retrieval is one of the three largest retrieval in the world, which is regarded as the global core, surpassing the core journals in China. Especially in China, publishing ISTP retrieval papers will get thousands of dollars in cash rewards or accumulated credits, which plays an important role in the evaluation of various professional titles and the graduation of masters and doctors.
ISTP search address (company database needs to be purchased): portal.isiknowledge
ISTP retrieval system provides two retrieval interfaces: full retrieval and easy retrieval;
Comprehensive search: provides comprehensive search function. Searching by subject words, author's name, periodical name, conference or author unit can limit the language, literature type and sorting method of search results, and can store/run search strategies.
Easy to search: the search function is relatively simple, and you can search for specific topics, people and places of interest.
Through the international conference organized, sponsored and co-organized by us, the paper will be sent to the ISTP retrieval center for retrieval. When the article is published at the international ISTP conference here, it will be included in the full text (English version) of the American ISTP database within 2-6 months. At this point, the author can log in to the ISTP database to retrieve his own articles.
When the article can be searched on ISTP, in order to facilitate domestic authors, we entrust the Sci-tech Novelty Retrieval Station of the Ministry of Education to issue an appraisal report to the author, that is, the index page and certificate of the full text of ISTP, and affix the official seal. This is an ISTP retrieval certificate, which has the official nature of the Ministry of Education. We provide it to our authors for free. We don't charge.
Question 5: What is the difference between the title, keywords, abstract, subject and full text in HowNet literature retrieval? Nomination is the title of the article;
Keywords: you can enter the desired information phrase at will, which is concise;
Picking chickens is the central idea of the article;
The theme is the meaning and theme of the article, which is generally related to the title;
Full-text is a text retrieval that can input or copy and paste large paragraphs of text.
I hope I can help you.
Question 6: What are the differences between the retrieval items such as title, keywords, abstract, subject and full text in literature retrieval, and how should they be applied in our retrieval process? My understanding is that the title generally refers to the title of a document, the keywords are the core vocabulary of the document extracted by the author, and the abstract is the summary of the content of the document extracted by the author. The theme is based on the title, keywords and abstract, generally including the contents of the three, and the full text is the text of the document. In the process of retrieval, generally speaking, the full-text retrieval range is the largest, the theme retrieval range is also larger, and the abstract retrieval range is not small, so the title and keyword retrieval is targeted.
Shallow understanding for your reference!
Question 7: CPC's search portal 1. CPCI-S(ISTP) search portal 2. The CPCI-S(ISTP) system provides two search interfaces: full search and easy search. Comprehensive search: provides comprehensive search function. Searching by subject words, author's name, periodical name, conference or author unit can limit the language, literature type and sorting method of search results, and can store/run search strategies. Easy to search: the search function is relatively simple, and you can search for specific topics, people and places of interest.
Question 8: What does the retrieval port mean in chemical literature retrieval? What retrieval port should I fill in the following picture retrieval port? Refers to the entrance of the information retrieval system, after which relevant information can be retrieved.
According to the following search terms and titles, the search term is "title".
