摘要：在信息爆炸的互联网时代，相对于传统考试的繁琐，效率慢的缺陷，在线的考试预约系统随之诞生，本系统不仅解决了传统考试的地点固定的问题，还解决了在考试过后处理的流程效率慢的问题，还提供了在线的练习题库，为广大需要通过考试获得证书以及其他的同胞提供了极大的便利。81788

本人在此系统中对评分模块的设计与实现，主要是针对于试卷的评分，评分又分为：自动评分与人工评分。对于人工评分大家也是比较了解，就不详细介绍了，这里主要重点是自动评分，本系统的自动评分主要采用的是基于字符串的分词算法结合文本相似度算法（VSM模型）进行一个自动评分。主要解决了传统考试的评卷效率慢的问题，为教师分担了很大一部分的工作量。并且评分的准确度也是比较高。

 Examination reservation system - Design and implementation of scoring module

Abstract: In the era of online information explosion ,compared with the cumbersome and inefficient traditional examination, online examination booking system was born。This system not only solved the   problem that traditional test place is fixed but also solved  the process of the slow processing efficiency after the examination, also provide practice questions online which provides a great convenience for the teachers to obtain the certificate and other people pass the exam。

In this system, the design and implementation of scoring module are mainly aimed at the score of the test paper, scoring is pided into: automatic scoring and manual scoring。 For manual scoring, people almost understand it ,so there is  no detailed introduction, here the main focus is automatic scoring, the automatic scoring system is mainly used in segmentation algorithm based on the combination of text string similarity algorithm (VSM model) is an automatic scoring。 Mainly to solve the traditional exam marking efficiency problem of slow, sharing a large part of the workload of teachers。 And the accuracy of the scoring is also relatively high。

Keywords: Online examination；Subjective scoring；The algorithm；Text similarity
