Plagiarism - A Survey

1 Journal of Universal Computer Science, vol. 12, no. 8 (2006), 1050-1084. submitted: 10/8/06, accepted: 25/8/06, appeared: 28/8/06 Plagiarism - A Survey Hermann Maurer (Institute for Information Systems and Computer Media Graz University of Technology, Austria Frank Kappe (Institute for Information Systems and Computer Media Graz University of Technology, Austria Bilal Zaka (Institute for Information Systems and Computer Media Graz University of Technology, Austria Abstract: Plagiarism in the sense of theft of intellectual property has been around for as long as humans have produced work of art and research. However, easy access to the Web, large databases, and telecommunication in general, has turned Plagiarism into a serious problem for publishers, researchers and educational institutions.)))

2 In this paper, we concentrate on textual Plagiarism (as opposed to Plagiarism in music, paintings, pictures, maps, technical drawings, etc.). We first discuss the complex general setting, then report on some results of Plagiarism detection software and finally draw attention to the fact that any serious investigation in Plagiarism turns up rather unexpected side-effects. We believe that this paper is of value to all researchers, educators and students and should be considered as seminal work that hopefully will encourage many still deeper investigations. Keywords: Plagiarism , cheating, similarity detection, IPR. Categories: , , , 1 Introduction Defining Plagiarism There are many definitions of what constitutes Plagiarism , and we will look at some of them in more detail below.

3 However, according to research resources at , the things that immediately come to mind as description of Plagiarism are: turning in someone else's work as your own copying words or ideas from someone else without giving credit failing to put a quotation in quotation marks giving incorrect information about the source of a quotation changing words but copying the sentence structure of a source without giving credit Maurer H., Kappe F., Zaka B.: Plagiarism - A Survey 1051. copying so many words or ideas from a source that it makes up the majority of your work, whether you give credit or not [ 2006]. The border-line between Plagiarism and research is surprisingly murky. After all, advanced research is only possible by standing on the shoulders of others, as it is often said.

4 In some areas (such as literature or law) a scholarly paper may well consist of a conjecture followed by hundreds of quotes from other sources to verify or falsify the thesis. In such case, any attempt to classify something as plagiarized vs. not-plagiarized just based on a count of lines of words that are taken literally from other sources is bound to fail. In other areas (like in a paper in mathematics) it may be necessary to quote standard literature just to make sure that readers have enough background to understand the important part, the proof of a new result whose length may well be below one third of the paper! In other disciplines like engineering or computer science the real value of a contribution may be in the device or algorithm developed (that may not even be explicitly included in the paper) rather than the description of why the device or algorithm is important that may well be spelled out in a number of text books.

5 In summary, we believe that there is no valid definition of even textual Plagiarism that is not somewhat domain dependent, complicating the issue tremendously. A good Survey of further ideas about how to define Plagiarism , and famous examples of suspected or perpetrated plagiarisms can be found in the Wikipedia1. Let us now turn, however, to an attempt to classify various types of Plagiarism : Plagiarism is derived form the Latin word plagiarius which means kidnapper. It is defined as the passing off of another person's work as if it were one's own, by claiming credit for something that was actually done by someone else . [Wikipedia: Plagiarism 2006]. Plagiarism is not always intentional or stealing some things from some one else; it can be unintentional or accidental and may comprise of self stealing.

6 The broader categories of Plagiarism include: Accidental: due to lack of Plagiarism knowledge, and understanding of citation or referencing style being practiced at an institute Unintentional: the vastness of available information influences thoughts and the same ideas may come out via spoken or written expressions as one's own Intentional: a deliberate act of copying complete or part of some one else's work without giving proper credit to original creator Self Plagiarism : using self published work in some other form without referring to original one [Wikipedia: Plagiarism 2006] [Beasley 2006]. There is a long list of Plagiarism methods commonly in practise. Some of these methodologies include copy-paste: copying word to word textual contents.

7 Idea Plagiarism : using similar concept or opinion which is not common knowledge. 1. 1052 Maurer H., Kappe F., Zaka B.: Plagiarism - A Survey paraphrasing : changing grammar, similar meaning words, re-ordering sentences in original work. Or restating same contents in different words. artistic Plagiarism : presenting some one else's work using different media, such as text, images, voice or video. code Plagiarism : using program code, algorithms, classes, or functions without permission or reference. forgotten or expired links to resources: addition of quotations or reference marks but failing to provide information or up-to-date links to sources. no proper use of quotation marks: failing to identify exact parts of borrowed contents. misinformation of references: adding references to incorrect or non existing original sources.

8 Translated Plagiarism : cross language content translation and use without reference to original work. Impact A Survey (released in June, 2005) conducted as part of Center of Academic Integrity's Assessment project reveals that 40% of students admitted to engaging in Plagiarism as compared to 10% reported in 1999 [CAI 2005]. Another mass Survey conducted by a Rutgers University professor in 2003 reports 38% of students involved in online Plagiarism [Rutgers 2003]. These alarming figures show a gradual increase. The new generation is more aware of technology than ever before. Plagiarism now is not confined to mere cut and paste; synonymising and translation technologies are giving a new dimension to Plagiarism . Plagiarism is considered to be a most serious scholastic misconduct; academia everywhere is undertaking efforts to educate the students and teachers, by offering guides and tutorials to explain types of Plagiarism and how to avoid it.

9 This growing awareness is forcing universities and institutes all around to help students and faculty understand the meaning of academic integrity, Plagiarism and its consequences. Since Plagiarism is often connected with the failure to reference or quote properly, many institutions suggest following one of the recognized writing styles as proposed by major publishing companies like Springer, or by using well defined citation styles like: Modern Language Association (MLA) style2, Chicago Manual of style3, or American Psychological Association (APA) style4. 2 Response of academic institutions Although Plagiarism is reasonably well defined and explained in many forums, the penalty for cases detected varies from case to case and institution to institution, Many universities in the United States have well defined policies to classify and deal with academic misconduct.

10 Rules and information regarding it are made available to students during the enrolment process, via information brochures and the 2. 3. 4. Maurer H., Kappe F., Zaka B.: Plagiarism - A Survey 1053. university web sites. Academic dishonesty can be dealt with at teacher-student level or institute-student level. The penalties that can be imposed by teachers include written or verbal warning, failing or lower grades and extra assignments. The institutional case handling involves hearing and investigation by an appropriate committee, with the accused aware and part of whole process. The institutional level punishments may include official censure, academic integrity training exercises, social work, transcript notation, suspension, expulsion, revocation of degree or certificate and possibly even referral of the case to legal authorities.
