Plagiarism Detection

Currently the most widely used plagiarism detection software is serviced by Moss

• ~give/stable/bin/ contains a couple of scripts to make the process easier:

• moss_setup - retrieve submissions and put them into directories suitable for moss-ing. Run this script from the class account.

• example:

• % ~give/stable/bin/moss_setup  21T2  ass1

  • a plague directory will be created under ~/12s2.work/assign1

  • Remove any files not to be included in moss plagiarism detection

• moss_run - wrapper script for moss, sends submissions to moss for processing.

• example:

• % ~give/stable/bin/moss_run  en1811  21T2  ass1  python  "*/*.py"

• % ~give/stable/bin/moss_run  -d /home/en1811/21T2.work/ass1/plague  python  "*/*.c\py"

• the last two arguments specify the programming language (python code) and which files to process (all .py files for each student).
• put template files under plague/Samples to ignore similarity from these files

• moss

• example:

• % cd $WORK/ass1/plague; moss -l python -m 4 -b template.py -d "*/*.py"
