Forms of Plagiarism in Digital Mathematical Libraries

Abstract: We report on an exploratory analysis of the forms of plagiarism observable in mathematical publications, which we identified by investigating editorial notes from zbMATH. While most cases we encountered were simple copies of earlier work, we also identified several forms of disguised plagiarism. We investigated 11 cases in detail and evaluate how current plagiarism detection systems perform in identifying these cases. Moreover, we describe the steps required to discover these and potentially undiscovered cases… Show more

“…with inhomogeneous text can lead to erroneous and even completely ridiculous conclusions. An exploratory analysis of different forms of plagiarism (explicit and disguised) observable in mathematical publications is presented in [21], where the authors investigated editorial notes from zbMATH and compared them to the results of current plagiarism detection systems. The investigation of the selected cases indicates that the application of the text-based iTh-system appears insufficient for analyzing similarities in mathematical publications.…”

“…This kind of autocomplete and error-correction type-hinting system would be beneficial for various use-cases, e.g., in educational software or for search engines as a preprocessing step of the input. Plagiarism Detection Systems: As previously mentioned, plagiarism detection systems [29,39,41] would benefit from a system capable of distinguishing conventional from uncommon notations. The approaches described by Meuschke et al [39] outperform existing approaches by considering frequency distributions of single identifiers (expressions of complexity one).…”

“…Fundamental knowledge on frequency distributions of math formulae is beneficial for numerous applications in MathIR, ranging from educational purposes [3] to math recommendation systems, search engines [22,25], and even automatic plagiarism detection systems [29,39,41]. For example, students can search for the conventions to write certain quantities in formulae; document preparation systems can integrate an auto-completion or auto-correction service for math inputs; search or recommendation engines can adjust their ranking scores with respect to standard notations; and plagiarism detection systems can estimate whether two identical formulae indicate potential plagiarism or are just using the conventional notations in a particular subject area.…”
