Detect Plagiarism
CodeGrade has integrated code plagiarism software to find possible plagiarism cases in CodeGrade assignments. This guide will walk you through setting up a plagiarism run.
Starting a plagiarism run on an assignment
- 1.Go to the Assignment Management page for the assignment you want to do plagiarism detection on by clicking on the Settings button.
- 2.On the Assignment Management page, navigate to the Plagiarism tab. This is where plagiarism checks can be run and where previous plagiarism checks can be reviewed.
- 3.Set up the options to apply to your assignment:
- Language: Language of the code in the assignment.
- Suffixes to include: Comma separated list of suffixes of files to include in the check. Leave empty to use the default suffixes for the selected language.
- Minimal similarity: The minimal average similarity to include in the results, the default is an average of 25%.
- Old assignments: Optionally one or more previous CodeGrade assignments can be selected, so that submissions from these assignments are included in the plagiarism check.
- Old submissions: Optionally an archive with assignments or codebase can be uploaded to be included in the plagiarism check.
- Base code: Optionally an archive with code to be excluded in the plagiarism check can be uploaded to reduce false positives. Use this to upload e.g. a framework used by all students.
- 4.Click the Run button to start the plagiarism check. A new entry will be created above the option fields and will display the progress.
- 5.When the plagiarism check finished, press the plagiarism run entry to display an overview of detected plagiarism cases.
- 6.The following Plagiarism Overview page displays an overview of all plagiarism cases between students (or optionally between supplied old code). Click on any row to investigate the specific case.
- 7.The Plagiarism Comparison shows two code views with the files that contain potential plagiarism, the actual individual plagiarism cases are highlighted with a colour corresponding to the colours in the top menu. Press these to compare manually.
Click the Export button on the top right hand corner to export a plagiarism report. Plagiarism cases can be exported in Docx or LaTeX format, so that additions and further comments can be added before exporting as PDF.
