An Anti-Plagiarism Add-on For WebCAT.

Abstract
Plagiarism is a major problem in every discipline and Computer Science courses are
no different. It is very common for students to submit their peers programming
assignment as their own. This practice is unfair and also halts the learning process of
the students who choose to copy. This research investigates the performance of
various software plagiarism detection tools such as MOSS, JPlag and Plaggie.
Controlled changes were made to a code file, and the sensitiveness of the various tools
to those changes was determined. Plaggie with its algorithm of tokenisation followed
by string comparison was found to have acceptable performance for our tests. It is
also open source whereas the other tools are proprietary and web based and we
decided to incorporate Plaggie with Web-CAT.
Web-CAT is a flexible, automated grading system designed to process computer
programming assignments. It serves as a learning environment for software testing
tasks and helps automatically assess student assignments. The developed system was
tested using submissions to a real class assignment and also by a variety of potential
future users in a number of tests and the feedback received was very positive. In
addition the tests presented a number of possible future enhancements.
