Research And Realization On Intelligent Question Answering System Of Distance Education

Under the development of scientists and technology, driven by the social needs, distance education as a new model came into being, and growing stronger. Compared with tradition teaching, on the one hand, it breaks through the traditional education in the teaching resources and teaching environment constraints, across the education space and time constraints, so that the universal sharing of educational resources has become possibility. On the other hand, distance learning because of technical characteristics of the learning process so that students self-learning become a reality. However, due to distance education teachers and students in the geographic separation, the learner has not had a teacher making an explanation face to face and deducing the study about being in progress is obliged to acting on self s own. So how timely resolution of such a large number of students the difficult issue is the implementation of distance education must be considered.This paper discusses intelligent question answering system to study the background and significance of analysis of the current system for answering questions at home and abroad of the status quo, in a comprehensive study of the question-answering system used in the technology and theory based on the design of an intelligent question answering system. Established covering the professional knowledge of information and answers to frequently asked questions and answers material library as the source material, the system issues raised by the students intelligent word, keyword weight calculation then full-text retrieval in the Q & A material library, Will students questions and answering the questions in material database similarity calculation. Find students to question the similarity of the problem, and the answer back to the student, realize the Q & A system's intelligence...
