Design and Implementation of Automatic Paper-Extraction System

文章设计与实现了一个试题自动提取系统，论述了该系统的特点及构建原则；阐述了系统的结构和功能；并详细描述了系统所采用的关键技术。系统针对考试系统中试题的自动提取展开研究，把试卷中的问题归类为试题库中若干张表，以解决试题库中人员管理问题、题型问题、课程问题及安全问题等。同时该系统对试题提取过程中的重复性问题、难度问题、章节问题等进行重点处理，在试题添加过程中加进适当的因子进行控制，以保证试题抽取的科学性、合理性和规范化。

In this paper， we designed and implemented the system employed for extracting test paper automatically. The paper concerns about the introduction of the main characteristics， the principles， the structure， the functions and specially the implementation of the system. Based on the studies on the effective implementation of the automatic paper-extraction system， we classifies the test questions to solve the problems， including the examination-related personnel management， question types， curriculum matters and safety factors. And also the paper notices the repeatability， the difficult level and the distribution of the test paper; and illustrates the science， rationality and standardization features of the automatic paper-extraction system by means of the appropriate factors.
