It is difficult to delete more than 80% of the text in a paper. Because a long paper has its own structure and layout, and the system is relatively large, if you just use the method of deleting text, it will lead to insufficient argumentation and lose the depth of the paper. The result will be a scratch-like summary, which can only be used as an introduction to this paper.
If it is necessary to reduce the length of the paper by 80%, the only way is to start with the structure. Most papers with more than 10,000 words have a three- to four-layer structure. For example, the topic of the argument is divided into several aspects, each aspect is further divided into several aspects, and then different aspects are discussed. Under the premise of extreme compression, compress the structure as much as possible, reduce the level of the structure, and remove secondary arguments. In this way, the size of the article will be smaller. On the basis of reducing the volume and refining the text, it is possible to significantly reduce the length.
