In short, literature review is to sort out and summarize some information or published papers in a certain research field. So what is a good summary? Why do you want to read the summary? Before starting a research project, many students are advised by their tutors to read classic review articles in their research fields. Read a review carefully, and you will have a general understanding of the research background and progress in this field. Today, papertime will tell you how to write an abstract of a paper.

1, determine the review topic.

Material people are afraid of choosing the wrong research direction, which determines whether we can easily publish periodical papers and apply scientific research results to the market.

There are many hot research topics in each era, some of which may be good papers published, but they have no practical use. After you make it, you can start a company to sell some information, but it can't be distributed well. The theme of reviews is the same, and the acceptance rate of reviews focusing on research hotspots is relatively high.

2. Relevant literature retrieval

After determining the theme of the review, you can start looking for relevant research papers.

The simple and easy way is to search the relevant review first and look at all the papers mentioned in it. A literature review refers to many literatures, so should these literatures be read carefully? In addition, there are many articles, we only look at its abstract, its purpose, method and conclusion are very clear, and this part of the article does not need to be downloaded.

3. Determine the review framework and sort out the literature.

This step is very critical. The theme is the foundation and the framework is the support. After the framework is determined, it can be sorted out.

The framework of general literature review is nothing more than abstract, keywords, introduction, classified introduction, development trend and prospect.

There are two commonly used content organizations:

Collating documents in chronological order: collating documents in chronological order, reflecting their historical evolution, latest progress and future development trend, and revealing the development context of this study. This method is especially suitable for summarizing the current iterative research fields.

Sorting by research topic: research in a certain field often focuses on different topics or a certain material category has different functions, and documents belonging to a certain topic or functional scope can be classified into the same category. This method is suitable for commenting on the fields with rich traditional research results.
