Abstract:A semantic pattern based user-interactive question answering system was proposed. The semantic pattern can sketch out the relationships among different elements in the sentence. The application of this semantic pattern in question parser improves the analysis of the relationships among sentence elements. Therefore,the accuracy of question analysis increase.It can be used for both English and Chinese question analysis. The knowledge base,which consisted of the pairs of question and correct answer selected by user,can be constructed during the running process of the system. The system can answer questions automatically by using the knowledge base.
Keywords:semantic pattern  question answering  pattern matching  semantic similarity  user interactive  question/answer pair
