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  12s2  assign1

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

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

• moss_run - send the submissions to moss for processing. The class accounts have no internet quota, so this script must be run from a personal account with access to the submissions.

• example:

• % ~give/stable/bin/moss_run  cs1911  12s2  assign1  c  */*.c

• % ~give/stable/bin/moss_run  -d /home/cs1911/12s2.work/assign1/plague  c  */*.c

• the last two arguments specify the programming language (C code) and which files to process (all .c files for each student).
