[gsoc] RAT 1 Cut&Paste Detector

[Tharindu Mathew <mc...@gmail.com>]

Hi,

I'm a student interested in the Cut and Paste detector.

I was wondering about the scope of this project. Does this iclude parsing
just a few regex strings to code search? Or are we looking at a
spohisticated mechanism where even a neural network maybe trained to
identify certain code patterns?


Regards,

Tharindu

Hello Tharindu,
Thanks for your question.

Simple methods work well for real-life tasks, while neural networks
may not. For example, I used regular expressions to  find multi-line
comments, and yes, most of them were copied. Also since legal matters
are involved, the simpler is our algorithm, the more understandable
are scan implications (and complications).

>From architectural point of view it would be nice to separate logic
into a separate module, so a sliding window could be easily replaced
with more sophisticated algorithms, even those you'd mentioned.

I wish you good luck trying GSoC this year.
