Electronic Job Management And Job Plagiarism Detection Technology Research

Coursework has been taking an important role in education and putting a direct impact on the quality, efficiency and the effect of it. Now people have won great achievement in instruction and examination through a series of innovation these years except Coursework. Unfortunately, it results in any serious problems for teaching.In this paper, an electronic Coursework management system is designed and implemented in order to improve the manage efficiency. We also introduce the key technologies of the system in details.The main work of this dissertation can be summarized as follows:(1) An email-based coursework automatically collected technology is proposed. As to the problems of long time span and more editions in the traditionalCoursework collected process, we propose an automatic method based on the email system, that is, the teacher define the coursework's name format for the first, then the students submit their work to the appointed email list using appendix pattern. A running thread will checked the email list automatically every certain period, downloading the work, analyzing their content and subtracting their attribute info, saving them into the database at last.(2) A new plagiarism detect technology based on the sentence similarity is proposed.The lack of an effective supervision in the assignment part let the cheating more and more serious. So, a plagiarism detect system is designed to find the cheater automatically instead of the manual operation in the past, it improves the detect efficiency greatly. We break the document into sentences, then calculate the similarity of the sentences in pairs and highlight the plagiarized documents' content. Finally, verify the algorithm with a lot of experiments.(3) A coursework management system is designedThe coursework management system is made up of four models: the collecting model, the teacher management model, the student management model and the plagiarism detect model. To the teacher, he can assigns coursework on line, evaluates them and does some stat later. To the student, he can submit his coursework, looks up its status, and even he can resets it only if it hasn't been evaluated. Every model related to each other together consist of the system.Above all, a lot of experiments are taken and it testifies that the system is so practical that it will greatly favor the teachers in the future.
