Keywords belong to a category of subject words. Subject words include not only keywords, but also narrative words of unit words and title words.
Keyword is a new vocabulary of information retrieval language, which is used to describe the theme of literature and give information retrieval. It is precisely because of its appearance and development that it is possible to computerize information retrieval (computer retrieval). Keywords refer to words or phrases that distinguish things by the characteristic relationship of concepts, express in natural language, have collocation function and accurately express the dynamic semantic conceptual relationship between words.
Keywords are keywords that mark the subject content of document construction, but have not been standardized. Keywords are words or terms selected from papers for document indexing to express the main contents and information items of the full text. A paper can choose 3~8 words as keywords.

The selection of the last three keywords supplements the main content information that the title of the paper fails to express, and also improves the conceptual depth involved. Need to choose, together with the keywords selected from the title, to form the keyword group of this paper.
