Abstract

In view of the lack of immediate question answering system for curriculums in current Chinese MOOC environment, an intelligent curriculum question answering system was designed and applied to MOOC platform in this paper by combining FAQ database and Web. In the stage of question analysis, the user's questions were reasonably standardized using domain dictionaries and N-gram model to effectively detect the errors in terms. Furthermore, web search engine, web crawler and automatic summarization technology were adopted to provide users with recommended answers for the questions which are not logged in the local FAQ database. The test results show that the correction rate of the text proofreading function of the question sentence is 85.3%; the accuracy rate of the answer summary based on web multi-document generation is 78.8%; the accuracy rate of the system is 87.3% and the recall rate is 89.3%.
