摘　　要：针对传统考试专用计算机智能判断系统存在相似度计算偏差大、判断准确度低、耗时长的问题,提出并设计基于COM技术的考试专用计算机智能判断系统。根据系统总体架构,以COM技术为指导,设计图像采集模块、Web服务器、COM服务器、COM库等硬件模块,将系统对象分为不同组件对象,完成试卷信息的输入、启动和管理。系统软件部分采用学生答案与标准答案对比的方式完成客观题的判断,采用关键词、句子的相似度计算方式完成主观题的判断,实现总体系统设计。实验结果表明,该系统的主观题相似度计算偏差较小,系统整体判断准确度高,可达90%左右,且该系统的判断时间少,仅为12.4 s左右,具有一定的使用价值。In allusion to the problems of large deviation of similarity calculation,low judgment accuracy and large time-consumption of the traditional examination intelligent computer judgment system,an examination intelligent computer judgment system based on the COM technology is proposed and designed.According to the overall architecture of the system,the hard-ware modules of the image acquisition,Web server,COM server and COM library are designed based on the COM technology.The system objects are divided into different component objects to complete the input,start and management of test paper infor-mation.In the software part of the system,the judgment of objective questions is completed by comparing students′answers with standard answers,and the judgment of subjective questions is completed by calculating similarities of key words and sentences,so as to realize the design of the overall system.The experimental results show that the system has small calculation deviations for similarities of subjective questions,high overall judgment accuracy of about 90%,and short judgment time of about 12.4 s,which has a certain value in use.
