Pmlc is a plagiarism detection system for college students' papers, which is also called China Knowledge Network's college students' papers management system. Different from other HowNet duplicate checking systems, PMLC has a unique "joint comparison database of college students' papers", which can detect the undergraduate graduation papers of previous students.
1. The joint comparison database of college students' papers is the database of HowNet, which undergraduates must check. It mainly includes undergraduate graduation thesis. Pmlc will be recorded in the system as long as previous graduates have used HowNet. Because students are not authorized to be included in HowNet, these articles are private papers that are not made public. Although these papers can't be downloaded through HowNet query, they can be compared by using HowNet pmlc. Therefore, undergraduate students choose PMLC as the most accurate, comprehensive and consistent duplicate checking system.
2. In the process of writing a thesis, college students will inevitably cite other people's achievements and theories, and a small amount of reasonable citation is allowed. However, as long as the repetition rate of papers and articles in the school detection system exceeds the range stipulated by the school, it will be regarded as plagiarism, which will lead to the postponement of the defense. Now, it is necessary and common for college students to check and modify HowNet in advance before submitting their papers to the school.
