The Research Of Automatic Question Answering System Based On Distributed Technology

With the popularization and development of Internet, online teaching has been paid more and more attention, emerged in a system with Internet large number of onlineteaching. This new approach to learning to overcome the limitation of the traditional teaching in terms of teaching resources and the teaching methods, students can notlimited by time and space, according to their own learning level and free time todevelop a learning plan and arrange the learning progress, realize personalized teaching students.However, whether the traditional teaching and network teaching, communication between teachers and students is very important. In traditional teaching, students andteachers can face to face communication, student questions can ask the teacher questions directly. While in online teaching, students and teachers generally cannotcommunicate directly, therefore, research and development of question answering system, which is an automatic answering system based on distributed becomes an important problem to solve the remote learning how to develop in network teaching.In the automatic question answering system at present numerous, mainly take the way to answer questions is fuzzy search by keyword matching or, this model has been unable to meet the needs of the people from all walks of life better, not users quickly locate the retrieval results. Using this model system interaction greatly and retrievalaccuracy. In this paper, combined with the Urumqi City nineteenth in the actual teaching, the automatic question answering system, through the analysis and Research on the advanced computer retrieval technology and computer application technology, according to the characteristics of question answering system, the naturallanguage understanding of automatic question answering system for a restricted domain support.Automatic question answering system in this thesis is a distributed informationretrieval technology based on Web, using Java language, the traditional question mode integrated into the computer application. The main research technique of thisproject includes four modules: distributed technology, Chinese word segmentation technology, based on XML 、 Ajax technology and Web application system development technology. The five major technology, complete the analysis and design of the main functions of the system. Through the computer technology will be word, full-text search in the database in a distributed retrieval technology to complete the fastestanswer questions online search, and return the exact answer.Based on the above key technology, realizes the automatic question answeringsystem based on distributed. Automatic question answering system that supportsnatural language question also has certain reference value in other areas. Keyword Database distributed technology Web application...
