Tools to Assist Detecting Plagiarism Source Code Analysis

Zeidman Consulting Codematch

Plagiarism Programme

The JISC Electronic Plagiarism Detection project was established to review electronic solutions to the issue of plagiarism. However, it became clear that, as with most things in life, technology can only assist us, it will never replace the expertise of humans and that the answer to problems usually lies in process and procedures not technology alone. Electronic detection has its place in institutions but the real solutions lie in appropriate assessment mechanisms, supportive institutional culture, clear definitions of plagiarism and policies for dealing with it and adequate training for staff and students. If these areas are improved, the need, desire, and appeal of plagiarism can be taken away for most students.

The JISC project was split into four strands, each examining a different aspect of plagiarism. The four strands included: a technical review of free-text and source code plagiarism detection software, a small pilot of free-text detection software and a good practice guide to plagiarism prevention. Each strand was carried out by institutions from the Higher and Further educational sectors under the central management of the JISC. At the end of the project, a series of workshops were held around the country where delegates were given an opportunity to hear the results from all the strands, to comment on these and to provide suggestions to the JISC on what further work needed to be carried out.

A set of web pages outlining the plagiarism project and related materials has been archived. The Plagiarism service is now in operation and has its own web site.

Plagiarism in Natural and Programming Languages: an Overview of Current Tools and Technologies

by Paul Clough, University of Sheffield, 2000. This report discusses in detail techniques used to hide plagiarism, legal aspects of proving that suspected plagiarism has taken place, and some of the tools available for detecting plagiarism. Although the report concentrates on text analysis, there is a large section devoted to source code analysis.

JISC (Joint Information Systems Committee)

JISC completed a four-strand project on the electronic detection of plagiarism in 2001, details of which can be found at ... http://www.jiscpas.ac.uk

The 4 sections were:

A technical review of free-text plagiarism detection software       

Discussing the effects of the internet on plagiarism in free-text work, and comparing the use of different systems for dealing with that plagiarism. This focuses heavily on the user interface and way in which results are delivered, rather than the validity of the results themselves. It also discusses value for money, reliability, and turn around time for submitted documents.

A technical review of source code plagiarism detection software     

This includes analysis of results from a questionnaire conducted on all UK universities as a background to the degree to which plagiarism in source code is considered a problem and where the main sources of the plagiarism are. It also surveys two leading source code plagiarism detectors – MOSS and JPlag.

A pilot of free-text detection software in five UK institutions

The results of a 6 month pilot conducted at a range of UK universities using iParadigms (Turnitin) software. This highlights a number of potential pitfalls, such as additional time needed to complete plagiarism tests and the necessary computer awareness required. It also considers the students’ reaction to the trials.

A good practice guide to plagiarism prevention                     

This document discusses not only the need for plagiarism detection, but also several necessary steps such as ensuring student awareness and ensuring consistent reactions to its detection.

Also, "Issues For Institutions To Consider" ...

This includes a paragraph on legal issues, alongside the need for student and staff training and the electronic submission of work.
