JPlag: finding plagiarisms among a set of programs

Prechelt, Lutz; Malpohl, Guido; Philippsen, Michael


JPlag is a system that finds pairs of similar programs among a
set of programs. It has successfully been used in practice to
plagiarisms among student Java exercise submissions.
Support for the languages C, C++ and Scheme is also available.
This report presents the design of JPlag, in particular the
algorithm, and carefully evaluates JPlag's performance on 12
different sets of Java programs.
The results indicate that JPlag will find all plagiarisms with
very few exceptions. The execution time is less than one minute
for submissions of 100 programs of several hundred lines
