Research And Implementation Of Intelligent Answering System For Massive Online Learning

President Xi Jinping pointed out that build the learning society that "everyone to learn,everywhere to learn,anytime to learn",with the development of information technology,promote education reform and innovation by letter of the International Education Information Conference.With the development of modern information technology,more and more online education has been developed.Massive open online course(MOOC)learning system is a new system for meet people education require in recent years.It is not enough to solve the students' problems in the asynchronous way,because of the huge number of learners of massive open online course and thousands of students who are enrolled has in a course of massive open online course,so it need an intelligent,automatic and synchronous answering system which helps teachers to solve the problem of students.The paper analyzes the advantages and insufficient of Intelligent question-answering system at home and abroad based on domestic and foreign existing question answering system,research on the theory of intelligent question-answering System,analysis of the influence factors of the learning effect of MOOC learner,research on text mining technology and its application in Intelligent Question Answering System,introduction the feature item extraction algorithm and improve the TF-IDF algorithm,improve the accuracy of feature selection by experimental verification.Study on the Chinese word segmentation algorithm and full-text retrieval theory,analysis and comparison of the existing Chinese word segmentation system and set up a custom dictionary and thesaurus to improve the answering system accuracy.On the basis of the characteristics of massive open online course learning education,the establishment of intelligent question answering system is proposed,which is suitable for MOOC.The intelligent question answering system is developed based on the related technology.The intelligent question answering system is developed for Massive open online course of the military learners,which is based on the educational technology of the dream by related technology.In question answering mode,the paper use of a multi-mode,which makes the intelligent question answering mode is more than just a text,It can be realized in a video mode.On the question answer by txt,which not only realizes the content of the knowledge base,but also extends to the teaching aids.It is reduce the pressure on teachers to build the knowledge base,teachers can only provide teaching aids to help students answer questions,without the need to build a huge knowledge base.The research and development of the Intelligent Question Answering System Based on the massive online course makes the development of massive online open education,improve the quality of teaching in massive online education,and guarantee the teaching activity of teachers and learners.
