I want to develop a plagiarism checker for checking several source codes but I couldn't find any proper source code or even a resource to get an idea about it. I have checked the Boss2 which is useless. they claim that they use Sherlock module for detecting plagiarism but it seems there is no such tools included in boss2.
if any open source detection tool is available for checking source code please let me know. regards
I'm aware of open-source plagiarism detectors for text (e.g., WCopyFind), but not code.
I couldn't find... even a resource to get an idea about it.
The authors of the excellent closed-source tool MOSS have published a helpful paper about the technology.
I know the question is old, but I did land here from a google.
Sherlock is an open source plagiarism detector. Sherlock's home page is here
I wrote SimiCheck, and you are welcome to use it. If you are interested in an API, I could probably write one very quickly. I wrote the original algorithm as part of the CrowdGrader peer-grading tool, but then I decided to make the comparison tools available independently. SimiCheck can handle code, Word (.docx), html, pdf, text, ..., as well as .zip, .tar, .gz, .tgz, and some more formats, and can deal with variable renaming, code moves, code across multiple files, etc.
