Academic Plagiarism Detection

Abstract

This chapter provides background information on academic plagiarism and reviews technical approaches to detect it. Section Chapter 1 derives a definition and typology of academic plagiarism that is suitable for the technical research focus of this thesis. Section 2.2 provides a holistic overview of the research on academic plagiarism to contextualize the technically focused research areas that the subsequent sections present in detail. Sections 2.3 and 2.4 systematically analyze the research on plagiarism detection methods and describe production-grade systems that implement some of the presented methods. Section 2.5 presents datasets usable for evaluating plagiarism detection technology. Furthermore, the section discusses comprehensive performance evaluations of plagiarism detection methods and systems to highlight their weaknesses and demonstrate the research gap this thesis addresses. Section 2.6 summarizes the findings of the literature review and thereby fulfills Research Task 1. Section 2.7 derives the research idea pursued in this thesis.
