STUDY ON BATCH MULTIMEDIA QUESTIONS IMPORTING BASED ON LEXICAL ANALYSIS AND XML TECHNOLOGY
摘要
Abstract
Question importing is a nodus facing by current online education.Traditional online question importing is characterised by low efficiency and high error ratio.At present,some researches on question importing based on lexical and syntax analysis focus on the plain text-oriented questions importing.However,through analysing the item bank of China Unicom internal training platform,it is found that the multimedia questions including pictures and videos appear frequently.In order to address this problem,in the paper we put forward a batch importing method for multimedia questions,it is based on lexical analysis and XML technology.First,the method pre-treatments the paper to get a standard test paper model.Secondly,by questions analysing it gets a test paper in HTML format and disassembles the questions and answers according to HTML tag information.Finally,it stores the“questions-answers”to database in XML format and completes the question importing.This method has been successfully applied to China Unicom internal training platform,which efficiently solves the problem of multimedia questions importing.Compared with existing questions importing methods,this one supports more question types and has higher importing efficiency and accuracy.关键词
