Computer algorithms for plagiarism detection

The Plagiarism Detection Systems for Higher Education - A Case Study in Saudi Universities

“…Literally, plagiarism means "taking or borrowing someone else's efforts and works and presenting them as the effort of work someone else" [3], [4] Plagiarism can be defined as "unacknowledged using of programs or documents" [7], but this definition is not clear enough, as it does not explain the term "use" deeply.…”

“…A lot of plagiarism tools are developed by researchers in order to be used for plagiarism detection but these tools have some difficulties as they cannot show an enough proof that the contents have been plagiarized from other sources, PD tools give the similarities and links to some other documents [3], [6].…”

“…Plagiarism Detection (PD) has been started since the 1990s basically in Natural Languages (NL) by using statistical techniques, which is promoted by the digital documents and the Copy Detection Mechanisms (CDM) [1], [2]. Software misapplied and code clone's detection has started before plagiarism detection in NL since the 1970s by detecting programming code plagiarism [3], [4] [5].…”

Computer‐based management environment for an assembly language programming laboratory

“…Plagiarism must only be declared when it is evident in the opinion of all the laboratory teachers. As teachers, our job is to actively look for plagiarism but within reasonable limits [13], keeping in mind that the ultimate goal of any plagiarism detection tool is to reduce plagiarism [14].…”

Java Birthmarks --Detecting the Software Theft--

“…A plagiarized program is defined as a program that has been reproduced from another program with only a small number of editions, and with no detailed understanding of the program required [32]. In order to detect plagiarized programs, various methods for similarity computation have been proposed based on attribute counting [33], structure metrics [28], [30], [31], and Kolmogorov complexity [29].…”
