Plagiarism in e-Learning
Introduction to Plagiarism in e-Learning
Plagiarism means imitating or copying intellectual properties of others without any acknowledgement. This was done for a long time for many purposes having the intention of theft or not.This phenomenon has increased rapidly in higher education sector like universities. Due to the fast development of technology, it is easy to collect the assignments of students via internet, but the lecturers faced a problem in correcting and checking the quality of the assignments. This has been a difficult task as going through the assignments and detecting plagiarized documents is a tedious work which is time consuming. Most plagiarism checking software available in the market are too much expensive and open source software usage for plagiarism is low and unreliable, therefore education sectors in developing countries cannot afford to use them. Also available open source learning management software like "Moodle" are lack of plagiarism detection module.Therefore, the idea has been arisen for developing a system for detecting plagiarism of students’ assignments and marking them easily.
The system basically is a web based module which can be integrated inside moodle. Users who logged to LMS can access the plagiarism module. It contains main three algorithms and plagiarism of a certain pair of assignments can be checked from three ways. Those methods are Advanced Matching Model (Ngram), Middle level Matching Model (Vector Space) and Basic Maching Model (Boolean). About the searching models several researches are done and papers are published on that.
