A Critical Evaluation of Jankowitz's Algorithm for the Detection of Plagiarism in Student Programs

Résumé du livre

Abstract: "It has been claimed that Jankowitz's algorithm avoids the limitations of previous approaches to the automated detection of plagiarism. In order to establish the veracity of such claims, a number of tests were conducted to assess the robustness and efficiency of Jankowitz's approach. In the context of this paper, robustness refers to a tool's ability to detect similarity when a perpetrator has disguised their plagiarism. Efficiency is viewed as the ratio of matches which a detection system reports to the number of cases of plagiarism which are confirmed by manual inspection. The results indicate that this Jankowitz's algorithm cannot distinguish between cheating and laudable instances of software re-use
