Abstract Taking huge amounts of QA records as study objects, the paper proposes a question classification method combining theme and categorization to form a basic framework for QA knowledge base. In this framework, knowledge records are divided into frequently used ones and non-frequently used ones, and an automatic question answering system is constructed. Experiments show that the new classification method can balance the distribution of QA knowledge, and help to improve the efficiency of the QA system.
