The MPC system was built as part of PhD thesis entitled "Effect of source-code preprocessing techniquers on plagiarsim detection accuracy in student programming assignments"

The MPC system eases the evaluation of detection tools so that it automates the underlying process of plagiarism detection.

The MPC system supports the process by preparing the data for the detection, giving the possibility to use preprocessing techniques, enabling the usage of multiple tools, visualizing the results in a unified form for all tools, and calculating the F-beta and other statistics needed for analysis phase based on the detection results. In addition the MPC system has integrated the calibration method, described in detail in Section 4.4, it supports the process of manual marking of plagiarised matches, enables creation of new combinations of preprocessing techniques, and it has the possibility for simple evaluation of preprocessing techniques. The MPC system can also be used as a simple plagiarism detection system by teachers which will run the detection on multiple tools and perform the desired preprocessing techniques.

The MPC system has four working modes where the main mode is the detection mode which goes through all phases of the plagiarism detection process. The other three modes are: 1) calibration mode – used for calibration in Section 4.4, 2) technique selection mode – used for technique selection test in Section 7.6, 3) statistics mode – used for calculating statistics that are input for the analysis phase (Chapter 8). The overall architecture of the system is presented in Figure 3.3, and in Appendix C a detailed description of the architecture is given.
