基于Lucene的试卷查重系统设计与实现

Design and Realization of Duplicate Check System for Examination Paper Base on Lucene

设计了一个用于检查试卷与往年试题重复率的查重系统,采用开源搜索引擎Lucene创建索引,将往年试卷转换成文本格式录入系统,形成索引库。对待查重试卷进行分题操作,将每道题目送入系统进行查重处理,然后将所有题目的查重结果汇总后计算出试卷的重复率。结果表明,计算机查重具有准确率高,处理速度快的优点。

T he system is designed to check the repetition rate of examination paper different from previous paper. Old examination paperchanging into text formatting is inputted into the index library which is created by open source search engine Lucene. When a paper is to bechecked the repetition rate, it needs to be divided into various questions firstly. Then the system will judge whether every question is the same asbefore and sum up the result. The test shows that the system nearly has the same accuracy rate with the manual result and has obvious advantagein processing time.
