KNN算法在智能试题库管理系统中的应用
Application of KNN algorithm to the intelligent test library management system
摘要
Abstract
Scientificity and rationality of automatically-generated test papers are the key to evaluating the quality of the intelligent test library management system . The quality of test papers generated automatically often depends on the properties of test questions , such as difficulty , discrimination and the average question-answering time .In order to determine the dynamic properties of the test questions automatically , this paper , based on the previous test library management system , applies KNN algorithm to the test library management system .Comparison of the test results indicates that the dynamic properties of the questions are more accurately forecast by using KNN algorithm , thus ensuring the scientificity and rationality of generated test papers and having important application value .关键词
