Abstract

Plagiarism among university students is an important issue that affects their preparation and undermines the universities’ efforts to prepare skilled graduates. Universities try to fight this problem back with strict ethics policies, but they require the proper plagiarism detection tools, at affordable costs, to implement these policies. In this paper, we present PlagZap, a cost-efficient, high-volume and high-speed plagiarism detection system built using open-source software and designed to be used on textual student assignments. We discuss the advantages of this design, plagiarism obfuscation methods and empirical results from using PlagZap.
