Main goal of this work is to get acquainted with the plagiarism problem and propose the methods that will lead to detection of plagiarism in program codes. In the first part of this paper different types of plagiarism and some methods of detection are introduced. In the next part the preprocessing and attributes detection is described. Than the new method of detection and adaptive weights usage is proposed. Last part summarizes the results of the detector testing on the student projects database

abstract: Plagiarism is a huge problem in a learning environment. In programming classes especially, plagiarism can be hard to detect as source codes' appearance can be easily modified without changing the intent through simple formatting changes or refactoring. There are a number of plagiarism detection tools that attempt to encode knowledge about the programming languages they support in order to better detect obscured duplicates. Many such tools do not support a large number of languages because doing so requires too much code and therefore too much maintenance. It is also difficult to add support for new languages because each language is vastly different syntactically. Tools that are more extensible often do so by reducing the features of a language that are encoded and end up closer to text comparison tools than structurally-aware program analysis tools. Kitsune attempts to remedy these issues by tying itself to Antlr, a pre-existing language recognition tool with over 200 currently supported languages. In addition, it provides an interface through which generic manipulations can be applied to the parse tree generated by Antlr. As Kitsune relies on language-agnostic structure modifications, it can be adapted with minimal effort to provide plagiarism detection for new languages. Kitsune has been evaluated for 10 of the languages in the Antlr grammar repository with success and could easily be extended to support all of the grammars currently developed by Antlr or future grammars which are developed as new languages are written. / Dissertation/Thesis / Masters Thesis Software Engineering 2020

Source code plagiarism is an ongoing problem in programming courses at higher academic institutions. For this reason, different automated source code plagiarism detection tools have been developed. However, they require several manual steps before the submissions can be compared. Linnaeus University uses GitLab to handle their students’ code-related assignments but lacks an integrated workflow for checking submissions against plagiarism. Instead, Linnaeus University’s plagiarism-checking process is done manually, which is a challenging and time-consuming process. This thesis is a case study on Linnaeus University, focusing on integrating one of the plagiarism detection tools with GitLab using Continuous integration pipelines. The objectives have been to collect students’ submissions, communicate with the plagiarism tool, and visually present the results within GitLab. The prototype has been evaluated by a set of manually created submissions with different levels of plagiarism to ensure that the detection tool differentiates plagiarized and non-plagiarized submissions. Teachers at Linnaeus University have tested the workflow and reasoned whether the prototype fulfills their requirements.

The dissertation is devoted to analysis of current practice and trends in providing repositories of electronic theses and dissertation (ETDs) in terms of their management, searching and dissemination. The first part presents terminology and the current state of access to ETDs in Czech and foreign repositories and includes results of a survey of the state of access to ETDs in the Czech Republic which was completed in 2014 by all public universities. In the second part, a metadata standard is presented, particularly the possibility of mapping EVSKP-MS metadata elements to other metadata formats and utilization within the OAI-PMH protocol. The issue of access to ETDs is dealt with further in terms of metrics for an evaluation of usage of distributed ETDs. Searching for ETDs is also described in case studies as are recommendations for public tenders for a discovery service and for creating an ETD metadata search server and an associated user interface with faceted search. The final part of the thesis focuses on the issue of plagiarism. This incorporates a presentation and analysis of the most important plagiarism detection systems and a case study of the development of the portal Validátor VŠE to provide access to results of document analysis.

Magister Bibliothecologiae - MBibl / The purpose of this study was to investigate plagiarism among undergraduate students at a higher education institution in South Africa. There is evidence from previous studies that plagiarism is increasing world wide among higher education students. The emergence of the Internet has made plagiarizing worse as students can easily copy and paste information from the World Wide Web. This study investigated the occurrence, causes and trends of plagiarism among students in the Faculty of Applied Science at a higher education institution. It also examines student awareness of institutional policies and guidelines regarding plagiarism. The methodology used to achieve the desired outcomes of this study was a quantitative research method. It involved the distribution of questionnaires to undergraduate students to gain information about certain aspects of student plagiarism. The participants were first, second and third year students of the departments of Chemistry and Mathematical Technology within the Faculty of Applied Science. The results of the study confirm that student plagiarism is fairly common within the departments of Chemistry and Mathematical Technology. The study shows that 41% of undergraduate students think that plagiarism is very serious, but plagiarism is still being practiced within these departments. It was also found that 73% of students admit to using the Internet to compile their assignments. This implies that the Internet is the most possible source of plagiarism. Students also used books and journal articles as possible sources to plagiarise. The study made recommendations regarding how a higher education institution can reduce incidences of plagiarism and make students more aware of the implications and penalties involved. Immediate responses that this higher education institution can do to prevent plagiarism, includes teaching students to be information literate, teaching referencing techniques and academic writing. Students must be assisted in understanding plagiarism by being made aware of the different forms of plagiarism and how to avoid being accused thereof. The institution must also fight technology with technology by investing in plagiarism detection software that will help academic staff to identify copied pieces of information. It is the responsibility of any higher education institution to create policies and guidelines regarding plagiarism and to ensure students are aware of their existence. Students should be informed about the procedures that will be implemented when dealing with cases of plagiarism

Anyone wishing to laud Matsepe for his literary ability should first turn to Ramaila who was not only one of the first writers in Sepedi, but also taught his people to read. Some of his short stories in the volume entitled Molomatsebe (1951) bear testimony to his narrative skills, particularly 'Tšhelete ya Sepoko' and 'Moloi ga a na mmala' which are complex in structure, like a detective story. Apart from the Molomatsebe collection, he also wrote other works such as Taukobong (1953), Setlogolo sa Batau (1938) and Tša Bophelo bya Moruti Abraham Serote (1935). In 1959 a volume of praise poetry was published that he had collected in the various Sepedi-speaking regions. These verses are not only of cultural historical significance but the volume is also a valuable addition to Sepedi literature. The greatest merit of the poems is found in the fact that they are authentic recitations. To the Bapedi Ramaila is a pioneer; he was the first author in Sepedi and encouraged his people to educate themselves. Ramaila had many followers of which Matsepe was the most important. In the pre-Matsepe period authors mainly wrote about the problems Blacks encountered under Whites in the cities. For this reason the 'Makgoweng motif' is often referred to in Sepedi literature. The works are generally sermonizing in tone and a moral lesson was usually included. Readers later found them very tedious, and when Matsepe appeared on the scene, he took the material for his stories from days of long ago. He, therefore, wrote about kings and heroes, and about war and hunting. Whereas stories written before were no more that short narratives, Matsepe created voluminous novels. He also wrote poetry and published six volumes, some of them of admirable quality. He was twice awarded the S. E. Mqayi prize for literature by the Suid-Afrikaanse Akademie vir Wetenskap en Kuns (South African Academy for Science and Art). During one of these award ceremonies he said that he had become tired of the preaching by his predecessors; he intended to regale his readers with absorbing reading matter. While Ramaila taught people to read, Matsepe exposed them to great literature. Because Matsepe's stories were so interesting, they met with general approval almost immediately. This led to a change of direction in Sepedi literature that could to a great degree be attributed to Matsepe's writing. This thesis deals with the influence Matsepe had on other writers. The most important factors determining such an influence are also examined. In this research the avenues of description, comparison and interpretation are expolored. The narratological model was chosen and adapted as a descriptive framework. The emphasis is mainly on the facts used by the authors and the manner in which they were put together. In the latter case this means that not only was the organisation of the information taken into account, but consideration also given to a similarity in the usage of specific word and phrases without reverting to stylistics. In defining the meaning of influence, the concepts of similarity, imitation, translation and plagiarism were also examined and identified. In this context various angles of influence are discussed. The influence of one author on another, influence emanating from literature itself and the influence arising from circumstances were noted. In the research several writers have been named who are said to have been influenced by Matsepe. These conclusions have not been motivated, however. In this study it has therefore been found that these pronouncements were made at random and that influence cannot be considered in all of these cases. On the other hand, a number of authors of the younger generation were discovered who are familiar with Matsepe's work and who are indeed influenced by him. This study has also revealed that Sepedi literature can be divided into two periods. First there was Ramaila period during which people learned to read and write, followed by a second period when readers were no longer interested in dull moral narratives, and thus a new generation of authors emerged. This can be designated as the Matsepe period although it includes writers who have only lately come forward and have not been influenced by Matsepe. The demands of circumstances for a change of direction in Sepedi literature may be ascribed to this. The fact that the second period heralded the growth of this literature is mainly attributed to the satirical nature of many of these works. / Thesis (DLitt (African Languages))--University of Pretoria, 2005. / African Languages / unrestricted

Prompt engineering is the craft of designing prompts in order to get desired answers from language models such as ChatGPT. This thesis investigates how ChatGPT, specifically GPT-4, can be used to detect plagiarism in simple programming exercises. We used a dataset containing seven different original solutions for programming tasks. Every programming task also contained solutions that were plagiarizing the original as well as solutions that did not plagiarize the original. After testing various different prompts on a subset of the dataset, four different prompts were tested on the majority of the dataset. Three of the prompts produced unreliable results to the point that simply guessing whether or not the task solutions were plagiarized would have frequently been more accurate. The fourth prompt was more accurate although still not accurate enough for it to be recommended to use ChatGPT in order to identify plagiarism. / Promptkonstruktion (prompt engineering) är konsten att skapa instruktioner som ger bästa möjliga svar från språkmodeller (language models) såsom ChatGPT. Denna avhandling undersöker hur ChatGPT kan användas för att upptäcka plagiat i enkla programmeringsuppgifter. Vi använde ett dataset som innehåller sju olika originallösningar på enkla programmeringsuppgifter. Varje programmeringsuppgift har plagierade lösningar som löser samma uppgift och icke-plagierade lösningar som också löser samma uppgift. Efter att ha testat olika instruktioner med ChatGPT på en liten delmängd av datasetet, testades fyra olika instruktioner på majoriteten av datasetet. Tre av instruktionerna gav opålitliga resultat till den grad att det ofta skulle gett ett bättre resultat att gissa om lösningarna var plagierade eller inte. Den fjärde instruktionen gav bättre resultat, men fortfarande inte tillräckligt bra för att rekommendera att använda ChatGPT för att identifiera plagiat.

Turnitin plagiarism-detection software was operating as a pilot program conducted by the Center for Teaching and Learning in Winter 2007 on the Brigham Young University (BYU) campus. A sample of 6 instructors and 79 student users participated in this evaluation. The evaluation findings show that Turnitin is compatible with the academic honesty environment created by BYU's Honor Code. Turnitin has been effective at detecting intentional and inadvertent plagiarism at BYU. It has also addressed the problem of multiple submissions of the same material. Recommendations are made for promoting Turnitin at the campus and department level. Training tools are proposed for instructors: a FAQ page, an online tutorial, and a set of guidelines for introducing Turnitin to a class.

Video game cloning is controversial within the industry, both because copyright laws do not protect game mechanics, and because people’s judgements about game cloning are unclear. Therefore, this study aims to examine the current literature related to game cloning and summarise the impact of cloning on the game industry, as well as the challenges faced by developers. A literature review approach was used in this study. The results suggest that game cloning has benefits for market competition and learning on the one hand and may be financially harmful to small studios on the other hand. A key point in determining whether game cloning is unacceptable is the motivation of the cloners. Furthermore, unofficial regulation, such as digital distribution platforms and communities, is an important means of combating game cloning.
