Recently there is a need for QA system to answer various types of user questions. Among these questions, we focus on record questions and descriptive questions. For these questions, pre-acquired answers should be prepared, while traditional QA finds appropriate answers in real-time. In this paper, we propose enhanced QA model by combining various pre-acquired answers in encyclopedia. We defined pre-acquired answer types, 55 Record Type(RT)s and 10 Descriptive Answer Type(DAT)s, in advance. To construct answer units, we built 183 Record Answer Indexing Templates and 3,254 descriptive patterns. We discussed how our proposed model was applied to the record and descriptive questions with some experiments.
