The so-called number of words in a paper includes the number of words in abstracts and references. Generally, the number of words is about 300, which is short and pithy. The following are the relevant requirements of several parts in a paper.

Nowadays, papers are often used to refer to articles that conduct research in various academic fields and describe academic research results, which are referred to as papers for short. It is not only a means of discussing problems in academic research, but also a way of describing academic research results in academic exchanges.

Keyword definition

Keywords are selected from the title, abstract and text of the paper, which are words with substantial meaning to express the central content of the paper. Keywords are words used by computer systems to index the content characteristics of papers, which are convenient for information systems to collect and provide readers with retrieval. Generally, 3-8 words are selected as keywords for each paper, and a new line is set at the bottom left of the "abstract".

Subject words are standard words. When determining the subject words, we should analyze the theme of the paper and convert it into standard words in the thesaurus according to the rules of indexing and collocation. (See Chinese Thesaurus and World Chinese Thesaurus).
