基于题型和知识点的组卷算法研究

提出了一种基于题型和知识点的组卷算法。全文首先介绍了试题库的结构,该组卷算法对应的整个试题库结构可以分成题型表、知识点索引表、试题表和试题内容答案表四个层次,其次讲述了组卷时组卷要求录入的格式,最后全面阐述了基于题型和知识点的组卷算法,其中详细阐述了算法实现的难点——保证试卷平均难度系数符合组卷要求的解决方法。

This article puts forward a kind of arithmetic of test paper forming ,which bases on question stype and knowledge point. First,The article introduces to a structure of test question database .The structure of the test questions database in the arithmetic of test paper forming can be divided into four form： the form of test question types, the index form of knowledge points, the test question form and the answers form. Secondly,it relates a format that input the request of test paper forming. Finally,it elaborates completely the arithmetic of test paper forming based on question stype and knowledge point, and elaborates detailed the solving method of the difficulty of realized arithmetic, that we must assure that the average difficulty coefficient of test paper accord with the request of test paper forming.
