The reason why this program born

When I did the assistant of the lecture. Some students highly disagreed with his homework was plagiarism. And this made me so mad.

So, I think that if I make the program that collects the evidence of plagiarism and runs it then students will agree on his plagiarism. And I created this.

Dependencies

This program was made by python3. So, you must be installed python3. And you have to install below packages by using pip3

tqdm == 4.40.2
nltk == 3.4.5
datasketch == 1.5.0
matplotlib == 3.1.2
networkx == 2.4

Details

This program finds the plagiarism by using the MinHash algorithms.

Usage

You can use this program like below (also can see this document with ./plagiarism.py -h)

usage: plagiarism.py [-h] [-t <template file name>] [-o <output file name>]
                     [-p <working path>] [-r <remove regex pattern>]
                     [-s <summary file name>] [-g <graph weight0.0 ~ 1.0>]

optional arguments:
  -h, --help            show this help message and exit
  -t <template file name>, --template <template file name>
                        set template file
  -o <output file name>, --output <output file name>
                        set output file
  -p <working path>, --path <working path>
                        set compare files path
  -r <remove regex pattern>, --remove <remove regex pattern>
                        set remove patterns(regex) in file
  -s <summary file name>, --summary <summary file name>
                        set summary file
  -g <graph weight(0.0 ~ 1.0)>, --graph <graph weight(0.0 ~ 1.0)>
                        show associativity graph and set weight(0.0 ~ 1.0)

Terminology

• template file: The template file refers to a file that is distributed in common. For instance, isn't there something always included when we create the hello world example? It serves to remove such content.
  • This value should be given as ~/dir1/dir2/template.c.
• output file: This is the storage location of the CSV file with comparison full results.
  • This value should be given as ~/dir1/dir2/output.csv.
• working path: This is the path that contains all the files you want to compare.
• remove regex: Contains the pattern the user wants to delete. Typically, it is used to uncomment the source code.
  • This value should be given as ~/dir1/.
• summary file: This is the storage location of the CSV file with comparison summary results.
  • This value should be given as ~/dir1/dir2/summary.csv.
• graph weight: Corresponds to the threshold value determines the target to draw in the graph.

TODO

- [x] Support a feature of creating the graph
- [ ] Add the function which has the cosine similarity analyzes
- [ ] Add the feature of plagiarism detect which based on c functions

catch-me-if-you-can's Issues

`--path` option doesn't work.

The current version doesn't work well with the -p options. For example, I suppose that I have a temp directory which has sample1, sample2, sample3 files.

In that case, I ran the program with ./plagiarism.py --path temp command. And then we checked the returns, we found that the program only returns sample1 sample2 sample3 which means it doesn't contain the temp directory information.

P.S. I attach the location of need fix lines.
