For question answering, the multi-source approach is justifiable especially when different sources provide different types of knowledge. In this paper, a variety of question and answer types are revealed. The key point this paper addresses under the framework of extensible QA is efficient and consonant usage of a number of distinct QA techniques for improving the answer confidence. To prove the extensibility of the proposed model, we started with four QA modules first and added two specialty modules to the system one by one. As a result, both effectiveness and efficiency are improved as we employ more specialized QA modules.
