An Evaluation of Web Plagiarism Detection Systems for Student Essays
نویسندگان
چکیده
This study uses purpose-built test data and empirical experiments to report on the performance of four web plagiarism detection systems: TurnitIn, SafeAssignment, Plagiarism-Finder and EVE. In addition to measuring accuracy of detection, we evaluated the extent to which these systems produce false detections. We obtained the test data from multiple sources and edited it in several ways to conceal the plagiarisms in the texts. Our results indicate that SafeAssignment was the best overall performer.
