The Design And Implementation Of Automatic Grading Examination System With Multiple Questions

With the gradual maturity of information technology,the level of integration between information and education is continuing to deepen.In the long term,education informatization is an important trend in the future development of education.At present,under the background of the guide government policies and IT progressive development,based on their information technology,schools have developed all kinds of test system,especially those colleges and universities with strength has achieved significant results.As a higher education school,Ling Nan Normal University should constantly develops its information-based education,conforms to the historical trend and seizes the development opportunity.The main content of this study includes the following content:Firstly,it summarizes the previous studies and the development status,and introduces the basic content and ideas.Secondly,the analysis of the demand for the automatic grading examination system with multiple questions,it includes the necessity,feasibility,functional requirements,security requirements,and so on.Thirdly,it introduces the design and realization of key ideas of this system,it includes technology of word segmentation,the one-way degree which bases on the fuzzy mathematics,the statements similarity which bases on check closeness and so on.Among them,the main contribution of this paper are,solving the problem which exist impacts between students' answers the standard answer which due to the different word order arising by the improved similarity measures.Fourth,based on the previous work,With the key tools and techniques such as ASP technology,Microsoft SQL Server,ADO.NET,B/S mode and so on,the article analyzes the overall design goals,architecture design layout,business process design,functional unit module design,it divides the system into three modules of different types of people,includes teachers,students and administrators,on the basis of data form,it achieves user management,generating papers,review papers,online examinations,automatic marking,performance management and other functions by calling the relevant database.Fifth,it tests the related functional of the system.At the end of the article,it also summarizes the content and puts forward the prospects of the research.The results show that because of the combination of one-way degree which bases on the fuzzy mathematics and the statements similarity which bases on check closeness,this system can improve the degree of accuracy of automatic grading of subjective questions.However,because the basic technology has not been fully mature,so the degree of accuracy of Scoring subjective questions need to promote.
