SimilaR: R Code Clone and Plagiarism Detection

Empirical Evaluation of Similar Defect Detection by Code Clone Search

あらまし 不具合修正時の修正前ソースコード片を検索キーとしたコードクローン検索による類似不具合の検 出を実証的に評価した.これまでにオープンソースソフトウェアを対象とした研究により,コードクローン検索 による類似不具合発見の有用性が確認されている.そこで本論文では,商用開発のソフトウェアを対象としコー ドクローン検索による類似不具合発見を商用開発の現場への適用する際の指針となることを目指す.対象はパナ ソニック MSE株式会社において三つの異なるプロジェクトで開発された 3 件のソースコードであり,試験工程 での不具合修正に伴う修正履歴が記録されたリリース済のものである.修正履歴に記録された不具合修正前の ソースコード片を検索キーとしコードクローン検索を実施し類似不具合を検出した.その結果,対象とした商用 開発においてもその有効性を確認できた. キーワード コードクローン分析,類似不...

Plagiarism Detection in Computer Code

The ease with which computer code can be copied by students presents opportunities for plagiarism on programming projects. Presently, instructors are provided with few tools (if any) that assist them in detecting possible plagiarism in an assignment. Therefore, the only solution is a tedious and error prone by hand check of student submissions, looking for similarity between any two. In this th...

iii Acknowledgement We feel a great sense of accomplishment to be able to complete this thesis, as part of the requirement for our Master " s degree. We would have not been able to do this on our own without the supports of the people whom are important to us. Firstly, we would like to thank our supervisor, Associate Professor Dr. Jonas Lundberg for his continuous support and guidance. His advi...

Review of Code Clone Detection

Now a days Copy and Paste of code fragments has been regularly practiced in development of software. Because of limitations of time and lack of knowledge programmers use this code strategy. This strategy is known as code cloning. Clones may cause many problems. Probability of errors and the maintenance cost is increased. Modification would be difficult because of clones. So it needs to detect c...
