- The “internet” is a well known technology among students nowadays. They use the internet in finding resources for their study and enhancing their learning activity. On the other hand, internet offer big opportunity to cheat by copying others work without proper acknowledgment or using free edited wikis as a reference, which is academically prohibited. This project proposes a system to detect the use of free wiki in academic final assignment. This system adopts the well known algorithm of text based plagiarism detection system, called Winnowing Algorithm, uses fingerprinting method in detecting similarity of document. The implementation of Winnowing Algorithm involves some stages. First, parse the string into smaller form using the N-Gram method which then called as gram. Then, calculate the hash value (integer) of each gram using the Rolling Hash technique. Finally, define windows from the hash values, and choose the fingerprint from the window. In the experiment of this system, we use recall and precision value of each kind of examination to choose which value of variable that will be used for the permanent value of system variable so the system can be efficiently used. We also examine the performance of every single function of the system. The experiment result also reveals that the time needed for the plagiarism detecting process using off-line source of comparator file is far lesser than using on-line comparator file.
