Problems solved by technology

However, since the TF and IDF values ​​need to be recalculated every time a new document is detected; therefore, the amount of calculation is increased and the efficiency is reduced
In other words, the TF-IDF method has poor adaptability in the environment of dynamic document input
[0011] In summary, the current plagiarism detection methods for electronic documents and electronic assignments have the following deficiencies: ① Cannot detect fusion plagiarism of multiple documents; ② The algorithm complexity is high, and the system efficiency is low; Under such circumstances, it is impossible to judge who is plagiarized and who is original

Abstract

The invention discloses an electronic homework plagiarism preventing system and method based on paragraph plagiarism detection. The electronic homework plagiarism preventing system comprises an electronic homework submitting device, an electronic homework receiving device, a plagiarism detecting queue device, an electronic homework analyzing device, a plagiarism detecting device and an electronic homework storage device. The method includes: the electronic homework receiving devices receives electronic homework submitted through the electronic homework submitting device and adds the same into the plagiarism detecting queue device; the plagiarism detecting queue device detects plagiarism by using paragraph as the detecting unit and combining effective paragraph judging. The method using paragraph as the detecting unit and combining a queue mechanism for plagiarism detection has the advantages that system efficiency and stability are increased while the electronic homework polarizing multiple electronic homework can be judged, the attribution of the original homework can be judged, and plagiarism prevention can be achieved.

Description

technical field [0001] The invention relates to the fields of intelligent information processing and computer technology, in particular to an electronic homework anti-plagiarism system and method for detecting plagiarism by using a computer system. Background technique [0002] With the wide application of computer application technology in teaching and the advancement of electronic document technology, more and more assignments are submitted in the form of electronic documents, that is, electronic assignments. Electronic homework makes homework neat, easy to read, beautiful, and easy to save; therefore, in more and more courses, especially computer courses, almost all homework is submitted and reviewed in the form of electronic homework. However, the reproducibility and ease of modification of electronic assignments makes plagiarism easier. In the absence of any anti-plagiarism measures, students prefer to use simple means such as copy and paste to complete their assignmen...
