Study And Application Of Intelligent Generating Test Papet Based On Set At Bandom Algorithm

At present, most of the universities of China has established various campus network system, but the basic applications focus on web sites and the BBS and more in-depth intelligent application is less. For example, the application through the campus network to achieve online paperless office, the sharing of teaching resources, online measurement, online learning and online examinations generally lagged behind. And today's computer online education become more and more widespread which application is more in-depth, so improving the utilization of campus, establishment of an efficient, practical set of teaching management, online tests and online examinations management platform for online education has become a an urgent demand.Principles of Computer Organization Course in the practical teaching requirements, I designed and implemented a web-based J2EE architecture test system which will achieve test database construction and maintenance, paper management (manual and intelligent test paper test paper), online examinations, online testing, automatic grading and scoring, personnel management and many other features.Analysis of the existing algorithms in several test paper, combined with the teaching platform in the test database structure and the number of examination questions is not a huge feature, the system uses a collection of random test paper-based algorithms to achieve the automatic test paper test database. The system uses the current popular B/S structure, using the client, web server and database server three-tier architecture. The system is developed by JSP technology.Analysis of the shortcomings of the traditional algorithm for random generation of paper,introduced the concept of the collection, reduce the scope of matching search,and the parameters definition and design of the algorithm is given.And Algorithm implementation process is described in detail. The concept of question stored was introduced which overcome the problems which can not find question number and repeatedly search the database.The algorithm is based on a collection of test paper and the title number pre-existing ideas. The algorithms overcome the defects of traditional algorithm for the random test paper back repeatedly matched. The algorithm also is simple and practical and speed and quality can meet the actual online exam system demand.
