Outline of Final Research Achievements

In this study, I improved the two source code similarity measuring methods that I had proposed in my former study, that were, "A similarity measuring method using reference vector (FRef)" and "A similarity measuring method based on author’s coding style (CM Algorithm)". I implemented the two methods to a programming class support system to achieve auto-scoring, plagiarism detection, and coding style evaluation functions. From the results of the evaluation experiments using a set of source codes produced by students in real-world programming class as test data, I confirmed high performance for plagiarism detection and coding style evaluation function while scoring function needed more improvement to be used in practice.
