Research Abstract |
In this study, we have developed a prototype system to detect source-code plagiarisms in programming courses. The system firstly constructs "programming style models" for each of students from "expression feature" of source-codes, such as a number of spaces after some specific characters like comma, the location of new-lines around braces, etc. Then, whenever a student submits a new source-code, the system uses the student's style model to validate if the source-code has been actually written by the student. We have tested the system in our laboratory and observed quite fair result over 80% of correct classification.
