Intelligent Expert System Based The Examination System

The test is in a teaching process important link, is between the teachers and students exchanges the information important channel, also directs the compulsory method which the student studies earnestly, therefore, certain frequency and the number of times stage test is necessary. Under the traditional test way, organizes a time complete test to experience 4 steps at least: Is artificial the volume, the examinee to take a test, to examine test papers artificially with the result statistics, this greatly increased teacher's work load, cut teacher's working efficiency, we are urgently needed enhance the test work the efficiency to lighten teacher's work load, simultaneously improves the test quality.Along with the computer, networking's rapid development and computer's day-by-day popularization, took a test from the traditional paper examination paper turns the computer test already to become the irresistible tidal current. Along with the computer information technology and the artificial intelligence technology's unceasing development, the computer test's condition day by day is also mature. Therefore, has developed many computer test system at present, they display in each kind of test are affecting.At present developed the use the test system to realize the following function: Sets the topic automatically, sets the topic stochastically, examines test papers the scoring, the online time test, the user account household management, the result to put on file and so on functions automatically. But they also have many deficiencies, mainly manifests in cannot realize the personalization to practice and to take a test effectively, takes a test has not manifested the hierarchical. After being similar to a student practices, the test many times, presents the topic to be many times redundant, the test system has not kept abreast of the situation according to student's reality to set the topic, the practice efficiency is not high; Simultaneously the system sets the topic the difficulty grasps does not permit, basic is the difficulty coefficient which realizes assigns, the system cannot adjust the difficulty coefficient auto-adapted; Moreover the system grading which tests to the student, specially operates the topic the evaluation is not very perfect. This article mainly applies neural network's correlation technique the teaching domain, has constructed one based on expert system's intellectualized test system, mainly uses in the neural network the BP neural network to realize the junior middle school information technology test system's intelligent group volume to have the volume problem and based on expert system's student individual evaluation question, lets the test system realize the intellectualization truly, can let the test reflect really each student's real situation and serves effectively each student.
