In this paper, we propose an approach of constructing the knowledge base for “Analects of Confucius”, which aims to help the correct understanding of “Analects of Confucius”. The content of “Analects of Confucius” has the characteristics that it has not been categorized by topics and always has comprehensive meanings. Thus it is necessary to build an framework to manage and build the knowledge base for it. The construction of knowledge base in the past work has been focusing on the research of the words and the shallow meaning and explicitly communicated meaning of the passages which can not be used for deeper meaning and implicitly communicated meaning. The present paper sets up an categorization system for “Analects of Confucius”, then based on it, the knowledge base is built by using pragmatics information with reference to utterance interpretation method in pragmatics. The question answering system adopts the knowledge base of “Analects of Confucius” and gives an assessment of it. The results show that the combined answer with pragmatics information and modern text interpretation outperforms the answers which are extracted only from modern text by 32.2%.
