Design And Implementation Of Online Question Answering System

With the rapid development of computer network technology and multimedia technology,its related technology has been widely applied to the teaching process.The online question answering system designed for teachers and students in secondary vocational schools provides students with a novel and interesting way of learning and a convenient way for teachers to answer questions.It can mobilize students' learning enthusiasm and improve the teaching effect,while reducing the workload of teachers.The main work of this paper includes:(1)This paper describes the requirement analysis,business process analysis and data process analysis of the online question answering system.Then,the overall design,module function design and database design of the system are presented.Finally,the system is implemented using ASP+MYSQL framework and the functional test are carried out on the system.(2)In view of the actual situation of the students in the secondary vocational schools where the author works,in order to mobilize the enthusiasm of students to answer questions and solve puzzles,the reward points function is designed.Asking questions or answering questions will get corresponding reward points.The functions of reward pointsranking and reward points exchange can stimulate students' learning enthusiasm and further promote the work of the question answering system.(3)In order to alleviate the pressure on teachers to answer questions,this paper studies the theoretical and technical basis of automatic question answering,and implements a similar question retrieval method based on SimHash,which achieves a good performance.
