Comparative Evaluation of Text- and Citation-based Plagiarism Detection Approaches using GuttenPlag

All are based on more or less sophisticated text analysis methods such as string matching, fingerprinting, style analysis etc. In this paper a new approach called Citation-based Plagiarism Detection is presented. It is suitable for identifying similar and plagiarized documents based on the citations used in the text. In contrast to text based procedures, the presented approach performs significantly better in identifying strong paraphrases, translated plagiarism and some cases of idea plagiarism. It is shown that detection rates can be improved by combining citation-based with text-based plagiarism detection. It is also shown that a large scale crowd-sourcing investigation as done in project GuttenPlag, which combines all other methods, delivered by far the best detection results.

In contrast to existing approaches, which analyze documents’ words but ignore their citations, this approach is based on citation analysis and allows duplicate and plagiarism detection even if a document has been paraphrased or translated, since the relative position of citations remains similar. Although this approach allows in many cases the detection of plagiarized work that could not be detected automatically with the traditional approaches, it should be considered as an extension rather than a substitute. Whereas the known text analysis methods can detect copied or, to a certain degree, modified passages, the proposed approach requires longer passages with at least two citations in order to create a digital fingerprint.

In addition, the effect of the ability levels of the examinees in answer copying pairs on the statistical properties of the GBT and ω indices have not been systematically investigated as yet. The current study simulated 500 answer copying pairs for each of 1,440 conditions (12 source ability x 12 cheater ability x 10 amount of copying) to study the empirical power, and 10,000 pairs of independent response vectors for each of 144 conditions (12 source ability x 12 cheater ability) to study the empirical type I error rates of the GBT and ω indices. Results indicated that neither GBT nor ω inflated the type I error rates and they were reliable to use in practice. The difference between statistical power was very small in most conditions, and GBT performs slightly better than ω. The interaction effect between source ability level and amount of copying was very strong while the interaction effects between cheater ability level and amount of copying and cheater ability level and source ability level was not remarkable.

Academic Dishonesty in the Second Language Classroom: Instructors’ Perspectives

Academic dishonesty (or “cheating”) is a serious, yet common problem in educational institutions across all age levels... more Academic dishonesty (or “cheating”) is a serious, yet common problem in educational institutions across all age levels (Anderman and Murdock, 2007). Research has focused mainly on how many students cheat, why and how they go about it, as well as how to prevent them from doing it (Beasley, 2004; Berry, Thornton, and Baker, 2006; McCabe, 1993; Park, 2003; Staats, Hupp, Wallace, and Gresley, 2009). Additionally, there is an interest in how faculty deal with this problem and why many do not take the required judicial measures expected by their institutions (Keith-Spiegel, Tabachnick, Whitley, and Washburn, 1998; McCabe, 1993).

In the Second Language (SL) classroom, unique and specific types of academic dishonesty occur that are not found in other disciplines, for example 1) assignments initially written in the native language (original or copied from a website) are translated into the target language with the help of online translators, or 2) help provided by native or proficient speakers (anything from asking for a single word, an expression, or a complete review, i.e. “going over the paper”).

For this study an online survey was administered to 81 SL instructors across 22 US colleges and universities. The questionnaire, among other questions, asked teachers to list the types of cheating they have encountered and rate the seriousness of the offense. It also asked what procedures, if any, they follow when encountering acts of academic dishonesty, how they decide the penalties to be imposed and what they do to promote academic integrity.

Results show that, although almost all instructors have encountered several cases of cheating, as many as a third decide to deal with students one-on-one rather than following the institution’s procedures, because: 1) they are not familiar with them, 2) they consider them to be too cumbersome, 3) they think procedures or penalties are too harsh on students, or 4) they believe that first-time offenses can be handled “locally”.

Plagiarism, Integrity, and Workplace Deviance: A Criterion Study

While links between demographic, personality, and situational factors have been found, previous research has not used actual plagiarism behavior as a criterion variable. Previous research on academic dishonesty has consistently used to self-report measures to establish prevalence of dishonest behavior. In this study we use actual plagiarism behavior to establish its prevalence, as well as relationships between integrity-related personal selection and workplace deviance measures. This research covers new ground in two respects: 1) That the academic dishonesty literature is subject to revision using criterion variables to avoid self bias and social desirability issues, 2) We establish the relationship between actual academic dishonesty and potential workplace deviance/white collar crime.

Culture and Unethical Conduct: Understanding the Impact of Individualism and Collectivism on Actual Plagiarism

Given globalization of business and recent business scandals, furthering our understanding of international ethics remains critical. Business students are the potential employees, managers and leaders of organizations in the future. In this study we focus on one form of unethical conduct by business students, i.e. actual plagiarism, and seek to determine the link between this behavior and cultural values of individualism/collectivism and associated stereotypes of Asian/Caucasian students. Our findings suggest that individualists plagiarize more than collectivists, and that no significant differences in plagiarism exist between Asian and Caucasian students, contrary to popular beliefs. The implications of these findings for scholars and managers are discussed.

Ethnicity, Acculturation, and Plagiarism: A Criterion Study of Unethical Academic Conduct

Most reports suggest that one form of unethical conduct – plagiarism – is on the rise in the business schools. Stereotypes of Asian students as being more prone to plagiarize are frequently found in the literature, though not concretely substantiated. This study used a behavioral criterion to examine the relationships among ethnicity, acculturation, and plagiarism in a sample of 158 undergraduate and graduate students. Significant differences in plagiarism behavior were found based on level of student acculturation, but not ethnicity. Considerations and implications for training and managing international students and workers are discussed.

Self-plagiarism occurs when an author reuses portions of their previous writings in subsequent research papers. Occasionally, the derived paper is simply a re-titled and reformatted version of the original one, but more frequently it is assembled from bits and pieces of previous work. Most journals have a requirement that no work offered to them. Also called Duplicate publication, multiple publication, or redundant publication publishing the same material more than once by Tansu. A full research was conducted to find evidence of self plagiarism by Tansu. Plenty of evidences come to light of a paper being published, in identical form, in two journals. This is a grievous breach of scientific ethics, because it represents fraudulent claims of originality. The breach is all the more serious if there is evidence of active intent to defraud, such as the provision of a slight different title, but an identical abstract or body.
