CrossCheck guidance: an analysis of typical cases of plagiarism in different disciplines

Most plagiarism cannot be judged solely by the similarities discovered when using CrossCheck. Based on experience of cross checking more than 2000 manuscripts from approximately 50 countries in different parts of the world per year, this project aims to provide 3-5 typical cases of cross checked plagiarism in three different disciplines covered by the Journal of Zhejjiang University-SCIENCE A/B/C ( (JZUS-A: Applied Physics and Engineering; JZUS-B: Biomedicine and Biotechnology; JZUS-C: Computers and Electronics). The typical plagiarism case analysis will be made into a list or a handbook that will be classified by discipline. For editors, they can learn how to deal with different kinds of plagiarism in different disciplines when using CrossCheck. For authors, these lists can act as an instruction for authors on plagiarism, from which they can learn more about plagiarism and CrossCheck, and know how to avoid being accused of plagiarism.

This research project was proposed by Professor Yuehong (Helen) Zhang and Dr Xiaoyan JIA, and will be conducted by them and their team (editors: Hanfeng Lin, Ziyang Zhai, Xinxin Zhang, Meiqing Jin, Chunjie Zhang).


The results of part of this research were presented at the CrossRef 2011 Annual Meeting, USA, 15 November 2011 (download the presentation, (PDF 745kb). The purpose of this survey was to investigate journal editors' use of CrossCheck to detect plagiarism, and their attitude to potential plagiarism once discovered. The following publication has arisen from this project: Helen Zhang, Xiaoyan JIA (2012). A survey on the use of CrossCheck for detecting plagiarism in journal articles. Learned Publishing 25:292–307  (doi:10.1087/20120408).

    Prevalence and attitudes towards plagiarism in biomedical publishing

    Plagiarism is a growing issue in scientific publishing domain. Information technology has immensely increased the accessibility of source literature, simultaneously making plagiarism easier then ever, but it has also enabled the development of plagiarism detection software tools. In order to detect and prevent plagiarism, we designed a research project to investigate two issues: the prevalence of plagiarism and attitudes towards plagiarism in the scientific community.

    The prevalence of plagiarism in a biomedical journal will be measured using CrossCheck, eTBLAST, and WCopyFind plagiarism detection software. All papers submitted to the Croatian Medical Journal (CMJ, an international peer-reviewed open-access journal; in 2009 and 2010 will be checked using plagiarism detection software, which will also search for possible sources and compare them with previously published papers and texts available in e-form on the Internet. All suspicious papers will be carefully analyzed to determine the extent and type of possible plagiarism.

    The questionnaire measuring attitudes towards plagiarism will be developed and validated. Attitudes will be measured on two cohorts: corresponding authors of papers submitted to the CMJ in 2009 (approx. 300 authors) and research fellows in biomedical sciences in Croatia (approx. 500 research fellows). By correlating the prevalence of plagiarism with attitudes towards plagiarism in the two study groups, we will attempt to identify cross cultural differences and reasoning behind such a behavior. Better understanding of plagiarism will contribute to the prevention and discouragement of such practice among authors. The obtained results will be used for creating guidelines for editors on using available software to detect plagiarism in manuscripts before publication.

    This is a research project proposed by Lidija Bilic-Zulle and collaborators from the Croatian Medical Journal and Department of Medical Informatics from the Rijeka University School of Medicine in Croatia.
