The writing significance of keywords
Keywords are words or terms selected from papers to express full-text subject information items, which are used for document indexing. As far as the specific form of scientific and technological information stored in the document library is concerned, the abstract is the "text" and the keywords are the "abstract" of this text.
Keywords are not only the key words to reveal the theme of the article, but also the key words to meet the retrieval requirements. This keyword is a language bridge between readers, authors and editors. For the retrieval department, it is a specific language symbol that is collected, indexed and entered into the computer database.
Keywords are the key to query articles. Because the title query article is limited to people who know this article; Using the author's name to consult articles is also limited to well-known authors.
In order to meet the needs of literature retrieval, keywords are put forward, that is, words that reveal the key content of articles are used as "guides" to guide searchers to find the required information accurately. At present, keywords have become the most frequently used information in retrieval.
