This Python 3 script takes two repositories and checks for "code clones," or code which has likely been taken from elsewhere, between the two. The algorithm used comes from Lee et al. (2018) - Tree-Pattern-Based Clone Detection with High Precision and Recall. There are four main types of code clones:
- Type 1: exact copies
- Type 2: copies with renamed elements (ex. variables)
- Type 3: copies that have been slightly modified
- Type 4: "semantic" copies (code that is not copied, but does the same thing)
This code checks for Type 1, 2, and 3 clones.
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
