1, keywords are selected from the title, abstract and text of the paper;

2. It is a meaningful vocabulary to express the central content of the paper;

3. Generally, 3-8 words are selected as keywords for each paper;

4. Format: Start a new line and arrange it at the lower left of the Summary.

First, the keyword specification:

Keywords are words or phrases that reflect the theme of the paper, usually arranged under the abstract, and the font size is different from the text. Generally, each article can choose 3~8 keywords, and multiple keywords are separated by semicolons, which are arranged from big to small according to the extension (conceptual scope) level of the entry.

Keywords are generally noun words or phrases, and in some cases there are verb words or phrases. English keywords corresponding to Chinese keywords should be marked. Chinese comes first, foreign language comes last. Chinese keywords are marked with "keywords:" or "[keywords]"; English keywords are marked with "keywords:".

Key words should be selected from the National Standard Chinese Thesaurus as far as possible; Important terms and names of new disciplines, regions, people and documents that are not included in the glossary can also be used as keywords. Keywords should be general technical terms that can cover the main content of the paper.

Second, the method of selecting keywords

The general selection method of keywords is: after the author finishes writing the paper, he selects from its title, hierarchical title and text (high frequency and key words).

Extended data

The national standard describes the keywords in academic papers as follows:

Keywords are words or terms selected from reports and papers for document indexing to express the information items of the full-text theme. As can be seen from the description, the key words of academic papers must be words or terms.

Here, it is necessary to explain words or terms. A word refers to a word that can contain a morpheme (the smallest meaningful unit in a language) or the smallest free-use unit in a language, and a term refers to a professional term in a certain discipline. However, many authors of academic papers not only use words or terms, but also use many phrases or phrases.

Such as hybrid/mixed finite element method, northwest Pacific subtropical high, static or no-load characteristic experiment, multi-sensor integration and data fusion, BSP program performance prediction tool and so on. Even in some professional editing journals, you can see keywords in the form of "countermeasures and suggestions, structural methods of scientific and technological editing, and integration of editing and proofreading".

Thus, the rational use of keywords, not only when editing articles, but also when writing articles. The keywords in the above examples obviously do not conform to the description of keywords in national standards, and are used improperly and unreasonably.
