Abstract :
Plagiarism in e-homework becomes increasingly severe. Based on the study of the research on e-homework plagiarism detection system and the key issues on e-homework plagiarism, an e-homework anti-plagiarism system is designed and implemented. Similarity of text, which is the plagiarism standard of an e-homework, is calculated based on TF-IDF and Vector Space Model (VSM) theory. It can detect the checking e-homework copied from one or more other e-homework, thus prevent most of the plagiarism. Most of the time, e-homework are uploaded in the last few minutes of the class, and Microsoft Message Queue is used to relieve the stress of the system by setting up an E-homework Upload Queue. Time preference tragedy is used, and it greatly reduces the plagiarism.
