【摘要】：互联网的普及使得资源和信息共享越来越便捷,社会各领域和行业都存着这拷贝和抄袭现场,高校学生的作业也存在这种问题。电子文件形式的作业难免存在大量复制粘贴的使用,这种现象越演越烈导致了作业抄袭难以控制,高校教育教学质量和教育教学水平难以衡量,任课教师无法通过作业反映学生掌握知识和上课反映的真实情况。因此,本文设计和实现的相似度检测系统对教育教学质量的提高具有重大意义。针对以上问题,本文设计和实现基于SSH的电子作业检测相似性系统,该系统在相似度检测算法的基础上,以JAVA为开发平台,采用SSH框架以轻量级数据库Mysql数据库为底层数据支撑。系统分为三种角色用户,分别为系统管理员、教师和学生,管理员具有最高权限,负责系统功能和数据维护;教师具有一般权限,对教师管理模块、作业收集模块、相似度检测模块和结果显示模块具有操作权限;学生具有一般权限,对学生管理模块具有操作权限。系统主要实现学生管理功能、教师管理功能、作业收集功能、相似度检测功能、检测结果显示功能、系统配置功能、用户管理功能和数据维护功能。本文首先调研本文检测技术和相似度检测技术,在详细对比各种算法性能优劣的基础上重点研究了基于向量空间模型的相似度算法,在此基础上设计了系统使用的相似度检测算法,然后本文对系统采用的结构、编码技术和数据库进行选型,最后采用工程化方式进行系统需求分析、系统设计和代码实现。作业相似度检测系统的自动化将极大程度上减轻教师作业管理的负担,提升学生作业监管力度。电子作业相似度检测系统是专门针对高校各学科各专业课程内容进行的相似度检测评判系统,学生提交作业后将首先进入相似度检测,只有经过相似度检测合格的作业才会提交教师批阅成绩,其他检测不合格的作业将自动返回学生重新进行更改提交。电子作业相似度检测基于文本检测和文本复制检测技术,从一定程度上审查作业抄袭度。
[Abstract]:With the popularity of the Internet, resources and information sharing is more and more convenient. This copy and plagiarism exist in all fields and industries of society, and this problem also exists in the homework of college students. The use of copy-and-paste in the form of electronic files is inevitable, which leads to the difficulty of controlling the plagiarism of homework, and the quality and level of education and teaching in colleges and universities are difficult to measure. Teachers can not reflect the students' knowledge and the real situation in class through homework. Therefore, the similarity detection system designed and implemented in this paper is of great significance to improve the quality of education and teaching. Aiming at the above problems, this paper designs and implements an electronic job detection similarity system based on SSH. Based on the similarity detection algorithm, the system is developed on the platform of JAVA. The SSH framework is based on the lightweight database Mysql database as the underlying data support. The system is divided into three kinds of role users: system administrator, teacher and student, administrator has the highest authority, and is responsible for system function and data maintenance. The teacher has the general authority to the teacher management module, the homework collection module, the similarity detection module and the result display module to have the operation authority; the student has the general authority, has the operation authority to the student management module. The system mainly realizes the functions of student management, teacher management, homework collection, similarity detection, result display, system configuration, user management and data maintenance. Firstly, this paper investigates the detection technology and similarity detection technology in this paper. On the basis of comparing the performance of various algorithms in detail, the similarity algorithm based on vector space model is studied in detail. On this basis, the similarity detection algorithm used in the system is designed. Then, the structure, coding technology and database of the system are selected. Finally, the system requirement analysis, system design and code implementation are carried out by engineering. The automation of homework similarity detection system will greatly lighten the burden of teachers' homework management and enhance the supervision of students' homework. The electronic homework similarity detection system is a kind of similarity detection and evaluation system which is specially designed for the courses of various disciplines and specialties in colleges and universities. Students will first enter the similarity detection after submitting their homework. Only the homework that has passed the similarity test will be submitted to the teacher for evaluation, and other unqualified assignments will automatically return to the student for resubmission. The similarity detection of electronic work is based on text detection and text copy detection technology to examine job plagiarism to a certain extent.
