Automatic Detection of Plagiarism Using Plug-ins for Management System Moodle

Internet ensures that every person has access to a large number of content and information from different areas and fields, but it has also become a threat to the entire academic community in the form of plagiarism or unauthorized downloading and using someone else's content. [1]. Since 1980., Jplag on Moodle platform was used for detection of plagiarisam in searching for compabilities in program codes. [2] Also MOOS plug-in proved to be reliable because less students were able to plagiarize in test version. [3] Similar solutions are possibile to use on other platforms: Moodle, Sakai, Merlin, Lumen, etc. For the purpose of testing and comparing the quality of plagiarism plug-ins, were have taken into consideration plug-ins for Moodle: commercial plug-in VeriCite and free plug-in Crot Pro. [4, 5]. In order to verify plagiarism, we submitted a document on the topic of diving. The created test document was in doc format, assembled with content from blogs, chats and Web pages by the method of copy/past. Goal of this research was to find similarities with Web feeds based on used content in the test document. Fifty different sources in English were used for preparing this document. With the commercial plug-in VeriCite tested on the platform Sakai (due to lack of free trial plug-in for the Moodle) and the free plug-in Crot Pro tested on the platform Moodle, we were attempting to verify if the submitted document contained plagiarism content. Searching for matches was primary based on remote Web sources. The criteria for performance measurement of the plug-in were the duration of process detection and the number of detected sources. Considering the large amount of time spent on detection process, Crot Pro has discovered a relatively small percentage of similarities with Web feeds. On the other side VeriCite has achieved outstanding results with very little expenditure of time and a relatively large percentage of similarities with the same Web feeds. The advantages of using such solutions are cost-effectiveness, extremely fast detection of plagiarism, simultaneous detection of multiple documents in different formats (doc, pdf, txt) and an easy way to install them into the LMS platform.
