This blog mainly introduces the computer major (mainly the software design major) ), some introductions on how to reduce the duplication rate in CNKI, as well as methods to reduce the duplication rate.
Many people think that CNKI’s plagiarism checking is very strict, but in fact it is not. After reading this article, you can at least reduce the repetition rate of your paper by 10%-20%.
In order to reduce the duplication checking of papers, you first need to know the duplication checking mode of CNKI.
1. Scope of CNKI duplication checking
First of all, you need to know what things your paper will be compared with to ultimately form a plagiarism check. At present, the main scope of duplication checking on CNKI is these.

For undergraduates and college students, the areas that are generally easy to repeat are actually mainly concentrated in these comparison databases:
1. Joint comparison database of college student papers
a> The joint comparison library of college students' papers mainly refers to the fact that when all undergraduate and junior college students graduate, their papers will be included in the joint comparison library of college students' papers. Therefore, for everyone’s papers on the Internet, as long as they are copied and pasted, there will definitely be a large amount of red. Especially if you copy the papers from the previous session, you must check for plagiarism.
Therefore, as long as you refer to previous papers, every sentence in them needs to be changed, and remember not to copy them exactly.
2. Internet resources (post bars, forums, etc.)
This is easy to understand. As long as it is online text, if you copy and paste it, it will definitely become popular.
As long as it is text from online resources, it cannot be copied exactly.
3. Internet document resources
Mainly refers to document resources such as Baidu Library and CSDN. As long as the text in the online document is included, it will also be checked for duplication.
As long as it is existing text in libraries, blogs, etc., it cannot be copied exactly.
4. Source code library
It is mainly the source code in your project. If the source code is not developed for the first time and written into the paper, it will almost become popular.
The code part must be changed. How to change it will be explained below.
2. How to check duplication on CNKI
1. Continuously identical characters are checked for duplicates.
In the early days of CNKI, if every 20 consecutive words were the same, it was judged as plagiarism. Now it is 13 consecutive words that are the same are plagiarism. In fact, this is to a large extent lowering the requirements, because the probability of repeating 13 consecutive words in a sentence is still very small.
2. Image duplication check
Now CNKI will automatically recognize the text in the image, but onlyPictures that are particularly close to word documents. (Many people think that writing the code in the form of pictures can avoid duplication checks, but the result is still popular)
3. Table plagiarism check
After CNKI has been updated in the past two years, it will update the papersCompare each table. It is mainly reflected in database tables, because there are many similar data types and data fields, which are easy to check and compare. (The probability of duplication checking is not very high)
As shown in the figure below, it is a duplication check of a database table. == CNKI will compare each table, and the data in each row will also be converted for text comparison. == Therefore, the table in this paper has also become popular.
The following will explain how to solve this problem.

4. The repetition rate of English plus Chinese characters is the final repetition rate
One thing to mention here is that it is not the number of Chinese characters displayed in your word, but the final number in CNKI character. The total number of characters recognized by CNKI is based on the sum of Chinese characters plus English characters.
As shown below, the paper has a total of 8545 words in Word
==After uploading to CNKI, the total number of words is 15742. == Mainly because English characters also account for 1 and a half (and the reason why the paper failed to pass the plagiarism check is that there are too many codes, all of which are popular)

The final result is indeed like this. The English code in this paper was checked for duplication. Finally, these codes were deleted and modified, and the code was directly reduced to 20%.

3. The easiest place to check for plagiarism
1. Text introduction of the introduction
When introducing the research background, research significance, etc. of the paper, you need to refer to a lot of information on the Internet. Some people directly copy and paste it, which leads to an explosion of fame. So this place needs to be written in its own language. For some sentences, you can express them in your own words, and you can create some related sentences yourself, just like writing essays in Chinese.

|---|---|
2. Introduction to entities (large comma descriptions)
Mainly reflected in the introduction of the attributes of entities, there will be a lot of hits. Many people use commas to separate attributes, one attribute after another, and they immediately become popular. ==The solution is to end it with 'wait'. For example, user entities include user ID, user name, etc. ==It is best to have corresponding E-R diagrams to make up for equal words.

3. The functional description of different modules
is mainly mentioned in the overall design part of the system. When describing the overall structure of the system, use commas and go all the way down. All functions will become popular. The reason is that the names of these function modules are similar to others. You can give a general overview, and then introduce the parts within the paper hierarchically using level 3 headings or serial numbers.

4. Checking table content for duplication
Duplication checking in the code part is mainly reflected in the database fields. Because many people’s projects are similar, the field names are also set during development. Some words of Chang Jian. Therefore, when writing the paper, you can modify the attribute names appropriately. Such as:Change username to usname; change password to paswd. And modify the relevant field length, from 255 to 157; from 11 to 13

5. Check the code part for duplication
In fact, the code part is not recommended for use in the paper. One English letter counts as one character, so many people know that there are not many Chinese duplication checks, but they all become famous in the code, resulting in failed duplication checks.
As shown in the figure below, the entire series of codes is put into the paper, but it is not necessary.
You can delete all public Maps, etc. Only keep part of the main code and add some comments
In addition, you can also useModify the attribute values in the code to reduce duplication checking (very effective). For example, 'type' in the code below is changed to 'tpe', and 'msg' is changed to 'mg'. However, some keywords cannot be modified, otherwise the semantics of the code will be affected.
Generally speaking, CNKI’s duplication checking is quite reasonable. Based on your own handwritten papers and referring to some of the methods in this article, you can effectively reduce the duplication rate of your paper.
I hope this article will be helpful to all students.
