The Research And Implementation Of Exam Intelligent Extraction Technology

With the development of computer application technology and online education,the combination of the relevant educational theories and methods of on-line examination,the computer has become the important tool for modern education.Examination is a very important part in the teaching process,the test paper is the key of the exam.Previous examinations with offline paper-based test,edit test question content mainly use software such as Word,thus there are a large number of test paper document file in.doc format.As online examination gradually developed,a lot of examination using the computer as a way to have a test.If test papers still use the traditional way of manual typing,it will be difficult to meet the development speed of question bank system.Therefore how to make best use of the computer technology to recognize and import the existing questions content from the test paper documents to the question bank system accurately of online exam system,it is an important research subject.This research paper's content focused on exploring the way to recognize the exam text intelligently in the test paper of the Word document and import the question content into the question bank system automatic.Firstly,this paper introduces the structure of test question in the test paper documents,and then introduce the way in which the technologies associated with Java technology to obtain the test paper document content.According to the structure characteristics of paper documents,uses the rules engine named Drools as an exam content structure analysis,extract different item part of the test question content,and then make the extracted content into the XML file which meet the QTI standards.Using Drools rules engine,the complex questions parsing rules can be separated from the coding business logic,so as to realize the test question content more intelligent and reduce human input work when try to import a lot of test paper documents.Finally,the function was applied to the original examination system of J2EE framework.Through the practical tests and verifications,the paper documents intelligence import system has received the good effect.
