Heilongjiang Province Economic Management Cadre Institute Of Automatic Marking System Research And Implementation

With the application of computer has penetrated into every field of the society, thecomputer has got rapid development in assisting teaching, and plays a role of liberation ofproductivity for teachers. Heilongjiang province economic management cadre college since itsestablishment, the progressive development and growth, has now developed into a Collegeswith million people, the paper developed an automatic examination system for its owncharacteristics.In many kinds of Examination System，Marking Technology for0bjectiveQuestions is very mature and used widely．But Subjective Marking Technology is developingslowly．The reason is that some key technology is not complement．such as AI，PatternRecognition,Natural language is still in initial stage researching．Subjective Marking Technologyis a key way to realize Examination On Line and Marking Automatic．Because of the Chinese complexity,variety and flexibility of the subjective examination,theautomatic checking over subjective examination is a main technical difficulty.Combined with theprocess of looking over examination paper of short answer in manual,this paper presented theknowledge represent of fuzzy conceptual graphs with weight based on conceptual answer inspecial course,and also designed and implemented the modular architecture of mark the testsautomatically.Through the test and analysis,the results of checking over subjective examinationautomatically are basically same with manuals,and the solutions are feasible.The results of thispaper have some referential value for automatically checking over subjective examination ofother course.Based on the research of current automatic test system, the author has developeda test system with automatic test and evaluation. The system adopts B/S structure design,convenient for teachers according to their username and password to login examinationincluded and online marking; in process of test paper generation, according to the difficulty ofquestions and the proportion of test paper; in the automatic evaluation module, system usingregular expressions algorithm and similarity measurement algorithm on examination questionsto evaluate the subjective questions automatic, at the same time, the system also designedonline teachers marking module to provide further protection for reviewing exactly.Finally the system has been applied to test and obtains the corresponding test data, by theobtained experimental data show that the system of student evaluation has accuracy and acertain value.
