It means to summarize the core of the paper in your own language, which should be accurate, concise and comprehensive.
A paper generally consists of title, author, abstract, keywords, text, references and appendices, some of which (such as appendices) are dispensable.
1, paper title
Requirements are accurate, concise, eye-catching and novel.
2. Contents
A table of contents is a short list of main paragraphs in a paper. (Essays don't need to be listed in the table of contents)
3. Platform for Action
It is an excerpt from the main content of the article, which requires short and concise content.
4, 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.
Pay attention to the topic selection
First, the topic should not be too long. Too long indicates that the author lacks the ability of generalization and abstraction. The topic requires refinement and conciseness, and efforts should be made to reach the level that one more word is too long and one less word is too short.
Second, there should not be too many core concepts, at most two, the best one. This requires the implementation of the "family planning" policy. There are more than two core concepts, so it is difficult to grasp the content of the paper. Too many concepts are likely to explain the concepts throughout and dilute the substantive content.
Third, the expression should be accurate. If the topic is ambiguous or ambiguous, then the paper is likely to stray from the topic in writing.
