Detection of Plagiarism in University Projects Using Metrics-based Spectral Similarity

Authors: Ettore Merlo

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
An original method of spectral similarity analysis for plagiarism detection in university project is presented. The approach is based on a clone detection tool called CLAN that performs metrics based similarity analysis of source code fragments. Definitions and algorithms for spectral similarity analysis are presented and discussed. Experiments performed on university projects are presented. Experimental results include the distribution of similarity in C and C++ projects. Analysis of spectral similarity distribution identifies the most similar pairs of projects that can be considered as candidates for plagiarism.

06301 Abstracts Collection – Duplication, Redundancy, and Similarity in Software

Authors: Rainer Koschke, Andrew Walenstein, and Ettore Merlo

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
From 23.07.06 to 26.07.06, the Dagstuhl Seminar 06301 ``Duplication, Redundancy, and Similarity in Software'' was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

06301 Summary – Duplication, Redundancy, and Similarity in Software

Authors: Andrew Walenstein, Rainer Koschke, and Ettore Merlo

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
This paper summarizes the proceedings and outcomes of the Dagstuhl Seminar 06301. The purpose of the seminar was to bring together a broad selection of experts on duplication, redundancy, and similarity in software in order to: synthesize a comprehensive understanding of the topic area, appreciate the diversity in the topic, and to critically evaluate current knowledge. The structure of the seminar was specifically formulated to evoke such a synthesis and evaluation. We report here the success of this seminar and summarize its results, much of which is a record of working groups charged with discussing the topics of interest.

06301 Working Session Summary: Presentation and Visualization of Redundant Code

Authors: Andrew Walenstein, James R. Cordy, William S. Evans, Ahmed Hassan, Toshihiro Kamiya, Cory Kapser, and Ettore Merlo

Published in: Dagstuhl Seminar Proceedings, Volume 6301, Duplication, Redundancy, and Similarity in Software (2007)

Abstract
This report summarizes the proceedings of a workshop discussion session presentation and visualization of aspects relating to duplicated, copied, or cloned code. The main outcomes of the working session were: (a) a realization that two researchers had independently generated very similar methods for browsing and visualization clone "clusters," and (b) a list of questions for visualization, particularly in relation to how the "proximity" of clones may relate to interest in the clone.
