Research And Implementation On Plagiarism Detection Technology Of Software Lab Assignments

With the development of Internet and Internet technology, electronic documentshas gradually became the copying tool, and also makes the cause of plagiarismbecome more and more. After the study of the behavior of students’ homework in thecampus university that students use electronic document copy has become acommon phenomenon. Colleges and universities need a technology to curb thebehavior of plagiarism.The homework submission module of the system requires a repetitive detectiontechnology to monitor students homework copy.Repetitive detection technologymainly adopts the classic string matching algorithm which is KMP algorithm. In theKMP algorithm, the improved algorithm has good time complexity, improve theefficiency of the repetitive detection.The repetitive detection module of the laboratory teaching management systemadopts B/S structure, Java EE technology and Jacob technology to realize thefunction of students’ homework copy detection.Java EE technology complete themodule of the framework’design, and Jacob technology realize the conversion of thedocument.In terms of repeatability test,it uses the improved KMP algorithm,and usesthe improved KMP algorithm as the main body algorithm to realize the repetitivedetection function. After the test, the laboratory teaching management system has thethe repeatability test’s function.
