在线考试主观题自动评阅算法分析与设计

An Analysis and Design of the Automatically-scoring Algorithm of Online Examination for Subjective Questions

在线考试已成为计算机辅助教学的发展趋势之一,然而在线考试还主要用于客观题(选择题,判断题等),由于各门课程都存在各种主观考试题,而在线考试系统很难实现主观考试题自动评阅,因此在线考试还很少真正推广使用。阐述"工程经济学"、"Oracle数据库"和"C#.Net程序设计"等多种课程主观考试题自动评阅的算法以及开发自动评阅主观题考试系统所需要的关键技术问题。

Online examination has become a developing trend of CAI.However,the online examination system is mainly used in the examinations for objective questions（e.g.choice questions and judgment questions）.Due to the fact that subjective questions are often required in the examinations of all the courses and it is difficult for the online examination system to automatically score the subjective questions,online examinations are actually seldom used.This paper expounds the algorithms applied the automatically scoring examinations of such courses as Engineering Economics,Oracle Database and C#.Net Programming and the key technical problems in developing an automatically-scoring examination system.
