Design And Implementation Of Intelligent Question Answering System In Distance Education

With the popularization of the distance education on Internet, answering questions of distance learning becomes one of the focuses that people pay close attention to. The distance education is a kind of education by learning courses. The question that students meet in learning process may be the doubt of focal point and difficult point of courses. Intelligent Question Answering System sets up the knowledge base of courses through teachers'understanding of courses. Answering to students'question is the process of searching the knowledge base for the matched answer. On the base of comparing the method and technology of implementation of domestic and overseas Intelligent Question Answering System, the application of Latent Semantic Indexing to set up course semantic selected, the solution of Intelligent Question Answering System based on Latent Semantic Indexing is put forward under the environment of distance education. The system is designed, and the information retrieval theory is researched for the system design. Xidian Wang Yuan Intelligent Question Answering System, which is the implementation and application in School of Network Education, Xidian University, is a implementation, which WEB program is developed by JSP. Finally, the system appraised, the intelligence of the system and the places needing further perfectness are pointed out.
