Citation-based plagiarism detection - idea, implementation and evalutation.
Béla Gipp · Bull. IEEE Tech. Comm. Digit. Libr. · 2012
Currently used Plagiarism Detection Systems solely rely on textbased comparisons. They only deliver satisfying results if the plagiarized text is copied literally (copyp yet, they fail to identify e.g. paraphrased, translated and idea plagiarism. By applying the citation-based approach to the doctoral thesis of Guttenberg, which is a well-examined, real world plagiarism example tested by numerous conventional Plagiarism Detection Systems, we could show that the citationbased approach is able to identify 13 out of the 16 translated plagiarisms. Conventional methods failed to identify any of these sections. However, as expected, short passages of copy&paste plagiarism can usually only be identified by text-based approaches. Therefore, Citation-based Plagiarism Detection is by no means a replacement for the currently used text-based approaches, but should be considered as a complement for identifying currently hard to find well-disguised plagiarisms. Additionally, once signs of plagiarism have been found, neither the text-based approaches, nor the citation-based approaches eliminate the need for manual examination.
